PRODUCT DESCRIPTION

WE MAKE THE WORLD LOOK PRITTY

SILVER WHITE

Silver White is the world’s most popular pearlescent pigment. The technology used to create the original silver white effect (Titanium Dioxide on Natural Mica) is the basis for the wide variety of colours and effects available today.

Silver White pearlescent pigment characteristics are the result of three main determinants:

SILVER WHITE

1) Substrate Colour and Smoothness 2) Particle Size Distribution 3) Metal Oxide type and Thickness

SUBSTRATE The most common class of pearlescent pigments consist of flakes or platelets of a material (“Substrate”) which differs in refractive index from the thin uniform layers of metal oxides deposited onto its surface. Different substrates define the final effect of pearlescent pigments. Pritty Silver White pearlescent pigments are based on 3 different substrates:

•Natural mica •Synthetic mica (fluorphlogopite) •Borosilicate (glass) Wet ground Natural Mica is the most commonly used substrate for pearlescent pigments; being a naturally occurring mineral, it has inherent variations in composition (colour), thickness, and smoothness, resulting in a more variable final product. The platelets of Synthetic Mica however, are significantly more uniform in composition, have a smoother surface, and a more uniform thickness. These properties result in both a cleaner (whiter white) bulk colour, as well as higher chroma interference colours. Borosilicate (glass) improves upon these properties one step further, being even more transparent, and having a similarly smooth surface in comparison to Synthetic Mica, resulting in an even more transparent, brilliant glitter effect (reflectivity), which adds great visual depth and dimension to the matrix into which they are incorporated.

SILVER WHITE

PARTICLE SIZE Based on the particle size of the substrate used, a variety of appearance effects can be achieved ranging from a soft glow to a brilliant sparkle. This variation in appearance (reflectivity) is used to create different effects depending on the desired result in the final application. Particle size also has an effect on apparent opacity. Smaller particles having a greater total surface area appear more opaque compared to larger flakes.

• The substrate quality • Calcination temperature • Deposition uniformity and thickness M < 15µm F 5-25µm N 10-60µm S 30-100µm L 50-250µm

Low gloss, very good hiding power, mostly used for shampoo, body lotion, personal care packaging and plastics. Silky gloss, good hiding power, the 2nd most popular particle size, it is suitable mostly for printing ink and plastics Pearlescent, hiding, the most popular particle size, it is suitable for most applications Shimmering, low hiding power, used for decorative paint, plastic or any application demanding a sparkle effect Glittering , non hiding, used for cosmetics, as well as the decorative paint market mainly in Middle East

Particle size distribution consistency is a very important factor used to define pearlescent pigment quality. Pritty provides particle size distribution report from laser tester on each batch.

ANATASE AND RUTILE FORMS OF TITANIUM DIOXIDE (TIO2)

SILVER WHITE’S MAJOR QUALITY CONCERNS

Titanium Dioxide exists in three mineral forms: Anatase, Rutile and Brookite. Only Anatase and Rutile are used in the production of pearlescent pigments. Rutile has among the highest refractive indices, at visible wavelengths of any known crystal, and also exhibits a particularly large birefringence and high dispersion. Therefore Rutile pearlescent pigments are brighter, whiter, with better coverage and UV resistance than Anatase pearlescent pigments.

Whiteness and Brightness

To make Rutile pearlescent pigments, Pritty uses Tin(IV) chloride (SnCl4, tin tetrachloride or stannic chloride) to catalyse the phase transformation from the Anatase to the Rutile (TiO2) crystal structure. Therefore, due to the additional processing Rutile pearlescent pigments are about $0.2/kg more expensive than Anatase. Pritty however offers a choice of either Anatase or Rutile Silver White pigment. All odd numbered Sliver White colour codes are Rutile, and all even numbered Silver White colour codes are Anatase. Although Rutile pearlescent pigments are characteristically more weather resistant than Anatase, they are still not completely suitable for high performance and long term durability. In some regions however, clients choose to use Rutile pearlescent pigments for exterior applications in cost sensitive markets, with the understanding that its durability is different from Pritty Nacreium line which is certified by Atlas USA as a high performance pigment.

3 main determinants define the whiteness and brightness of pearlescent pigments: With Natural Mica, the whiteness and brightness of the pearlescent pigments will be determined significantly by the quality of the Natural Mica platelets. Some low end pearl producers in China use very low quality mica to control the cost. Larger producers have the flexibility to use different qualities of mica for different clients depending on the price point. Pritty however, sources only high quality mica for all products. The crude mica flake preparation prior to coating is important for the mica milling process. Pritty uses a high calcination temperature (750-800oC) prior to milling, resulting in a pearlescent pigment that is brighter (smoother surface, better reflectivity), with improved hiding power. Lower temperature calcination (400450oC) used by some manufacturers results in pearlescent pigments with less brightness (lower reflectivity), and are lower in opacity, but whiter due to increased scattering of the light. Other producers chose not to calcinate the mica at all, to produce the whitest silver pearl. However, this type of pearl not only has limited brightness and hiding power, but also has very poor oxide adhesion to the surface of the mica. Pre-calcination of the mica

SILVER WHITE

prior to coating helps the oxides bind to the surface. Without prior calcination, the probability is greatly increased for stripping the oxide layer off the mica surface when exposed to sheer forces, resulting in the development of a grey appearance during incorporation into a coating or plastic matrix, for example. The quantity of the Titanium Dioxide coating deposited onto mica is another very important determinant affecting pearlescent pigment brightness and whiteness. The process of depositing the oxide layer (TiO2) on the mica substrate is the most critical stage in the production of pearlescent pigments. TiO2 is whiter than mica therefore the more TiO2 coated onto the mica substrate, the whiter the pearl will be. However as an upper limit, if more than 25% TiO2, based on total volume is used, the pearlescent pigments will begin to have a yellowish hue. For example; Pritty’s Silver White Iridesium 100 is made with 2527% TiO2. This percentage of TiO2 allows the pearl to be brighter with better hiding power, but it has a more yellow cast when compared to products using 21-25% TiO2 from other producers. When 39% TiO2 is used, the pearl is not white any more, it turns into Interference Gold. Colour differences can be seen in two ways: 1-Bulk colour, often seen at the diffuse angle, or over the white portion of a Lennetta card. 2-Reflection colour, seen over the black portion of the Lennetta colour card. Pritty Silver White’s yellowish hue is mainly perceived at the diffuse angle, however when observed in a drawdown, where the reflective colour can be seen (spectral angle), Pritty Silver White will not appear to have a yellowish hue, it only looks brighter. Therefore, it is often perceived as being more desirable for coatings and printing ink applications.

APPLICATIONS WHERE WHITENESS IS CRITICAL Brightness is a more important property in coloured plastics; however in white pearl plastics, whiteness is less forgiving when it comes to the perception of whiteness versus brightness, plus with plastic application it usually comes down to a cost versus effect issue. Cosmetics: Whiteness is especially important for foundation powders as the pearlescent pigments must be colour neutral.

•Oil Absorption:

Pearl’s oil absorption is defined as how much oil the pigment absorbs before turning from powder to a dough. The less oil the pigments absorb, the better a reported oil absorption value. Oil absorption could affect the viscosity of some media, especially in the printing ink industry. Pritty offers special treatments to lower the oil absorption with extra charge and a longer lead time. A typical decrease is approximately 10gr/100gr (for example from 70-80gr/100gr down to 60-70gr/100gr). It is also possible to modify the oil absorption range to be narrower upon request.

•Dispersion:

Pearlescent pigments in general are extremely easy to disperse with simple low sheer stirring, compared to organic pigments, which require energy be put into the system to develop optimum colour value. Therefore, pearlescent pigments usually do not require a pre-dispersion step. However, pearlescent pigments, if desired, for ease of handling, may be pre-dispersed by using either solvent or water, depending on the media to which they will be added. With low viscosity media such as rubber latex, pearl slowly settles due to its relatively higher specific gravity (density). If the viscosity of the media is medium to high, the tendency to settle is greatly reduced. However, for low viscosity liquid media, pearlescent pigments will undoubtedly settle over time. This is primarily a problem for rubber (balloons, gloves, toys) applications. Pritty has developed a special product to solve this problem, by post treating the pigments with special dispersion aids.

GENERAL INFORMATION FOR PRITTY SILVER WHITE •Iridesium 100(Anatase): The most popular pearl used world-

wide, extremely price sensitive.

•Iridesium 103 (Rutile): Similar to Iridesium 100. Often used

for interior and exterior coatings in certain regions and for applications in plastic where more UV resistance is needed. Iridesium 103 is further processed with humidity and temperature resistant to produce Nacreium 9103.

•Iridesium 120 (Anatase): Most popular for plastic. •Iridesium 123 (Rutile): Similar to Iridesium 120. Usually used

for printing ink, due to its hiding power, brightness and small particle size.

•Iridesium 123M: Is based on Iridesium 123. It has been specif-

ically developed for the printing industry. Compare to Iridesium 123, Iridesium 123M is whiter, it has better hiding power due to a narrower particle size range, and more importantly, it has reduced oil absorption for better viscosity control. The normal oil absorption of Iridesium 123 is 70-80gr/100gr, for Iridesium 123M, the oil absorption decreases to 65-75gr/100gr. Upon special request Pritty can make it even further down to 60-70gr/100gr, with an extra charge.

•Iridesium 100T and Iridesium 120T: Are processed from

Iridesium 100 and Iridesium 120 for better dispersion and are specially designed for rubber applications. Both pearlescent pigments have better dispersion properties and a decrease in their tendency to settle, or hard pack, compared to normal Iridesium 100 and

SILVER WHITE

Iridesium 120. With Iridesium 100T and Iridesium 120T they can be easily re-dispersed without losing any lustre.

•Iridesium 100W: Based on Natural Mica is either uncalcined or calcined at a low temperature so the mica is whiter. This product is specially produced for plastic and cosmetic applications.

•Iridesium 110 YR & Iridesium 120 YR (Yellow Resistant):

Are especially designed for use in polycarbonate plastic applications, where due to a chemical reaction with the polycarbonate the pearl plastic matrix has shown a tendency to yellow. Pritty has developed a special anti-yellowing pigment version to prevent such a defect.

COMMERCIAL INFORMATION Considered as a “Commodity”, Silver white is a basic product with low profit and large volume. For both producers and distributors, it is a strategic raw material in terms of product turnover and brand positioning. Pearlescent Pigment’s special characteristic is its lustre effect (brightness). Stronger lustre effect requires a more advanced technology and defines better quality pigments, however it results a slight higher production cost. Pritty chooses lustre effect over whiteness for better pearl effect finishes. Pritty provides 60% of its Silver White to the Coatings Industry which prefers a brighter pearlescent effect.

INTERFERENCE

INTERFERENCE The colours created by pearlescent pigments are from thin coatings of Titanium Dioxide (TiO2) onto a platelet substrate. The thickness of the Titanium Dioxide layers is strictly controlled to create what are called interference colours. Interference colours can achieve all the colours of the rainbow, with each individual pigment having a characteristic single reflection colour at the spectral angle. It is the result of an optical effect caused by constructive or destructive light interference. In producing Silver White pigments 25% of total mass is TiO2. However, when a higher percentage of TiO2 is coated on the substrate, the colour changes from white to gold, to red, to purple, to blue, and finally to green. Therefore, the interference colour depends on the TiO2 coating thickness. For this reason, the control of colour consistency is very demanding, between one colour and another such as gold and red for example. In this case the difference in the TiO2 thickness is on the order of a few hundred nanometres. While there are many hues and saturations in between, there are only 5 standard colours (gold, red, purple, blue, green) that can be achieved with TiO2 and mica.

High Performance Interference Colours:

When producing Interference colours, gold has the thinnest layer of TiO2, and green has the thickest. However if more TiO2 is applied, green will change to gold and the process will continue again through all the colours until green is reached a second time (Second Order Colours). To continue the process of adding more TiO2 beyond green requires more advanced technology. Prittyâ&#x20AC;&#x2122;s new colour Iridesium 7235 is developed with this special coating technology where the colour must have its own defined layer thickness to reach the maximum colour value.

Colour test:

The optimum way to test and compare interference colours is in a drawdown over black and white, not in bulk powder form. Interference colours with very different quality show little difference in their powder forms. Interference colours are essentially light wavelength separators. They separate the wavelengths of light based on the changing refractive indices between the oxide and substrate layer interfaces. Thus they separate white light into its individual components through constructive and destructive interference resulting in a transmission and reflection colour. Over white, the transmission or complimentary colour to the reflection colour is seen; over black, the transmission colour is absorbed and only the pure reflection colour is perceived. This allows for the hue, chroma and value to be perceived visually and is normally used as the preferred quality control method to measure batch to batch consistency.

GENERAL INFORMATION FOR PRITTY INTERFERENCE

COMMERCIAL INFORMATION The most popular applications for Interference colours are Plastics, Cosmetics and Decorative Paints. Very often they are mixed with other colours, for example, Gold 205 can be mixed with an organic yellow or it can be mixed with a complimentary colour, such as organic blue to create extreme highlights. The most popular particle size is 10-60µm which comprises approximately 80% of the market, and to a lesser extent 5-25 µm and 10-100µm.

GOLDEN LUSTRE

Gold pearlescent pigments are the second most popular pearlescent pigments in the world with a vast market share and ample variety of common applications. Gold pigments display highly intense and lustrous gold effects. Gold pearlescent pigments are produced by mica platelets coated with combinations of Titanium Dioxide and Iron Oxide. The different Golden Lustre shades are obtained by varying the ratio of Iron Oxide to Titanium Dioxide. Particle size affects the level of brilliance and lustre. Pritty produces 3 different particle sizes in the TiO2/Fe2O3 family: 10-60µm, 5-25µm and 10-100µm.

GOLDEN RUSH

•Iridesium 3305:

Similar but not an exact match to Iriodin Solar Gold 305. Its particle size is 10-60 µm. It is produced primarily from synthetic mica with a small proportion of natural mica, thus it is more sparkly but with slightly less coverage. Iridesium 3305 has a slightly reddish hue on white backgrounds compared to Iriodin 305, on black background the effect is very similar. Therefore, depending on the application, some end users would accept Iridesium 3305 as a replacement of Iriodin 305 Iridesium 3305 is significantly more economical than Iriodin 305 Applications: Usually for Decorative Paint, Industrial Paints and Wall Paper. Plastic applications are not recommended due to its reddish tone at the off angle.

•Iridesium 305M:

After years of development, Pritty has launched an offset to Iriodin Solar Gold 305, the only greenish gold pigment in the market for more than 20 years. Offsets from other Chinese companies are reddish and normally based on Synthetic Mica. Iridesium 305M is the best Iriodin 305 match from China, with particle size range of 10-60 µm, it is made of 100% Natural Mica. Because of the greenish shimmer, it has the appearance of 24K gold. It also has excellent opacity, and great colour consistency.

•305M Applications:

•As an inorganic mineral, Iridesium 305M is non-toxic and FDA compliant, thus is suitable for food and personal care packaging, as well as for toys. •When used in plastic, due to its great hiding power, just 1% in transparent plastic can create a pure gold effect. •Iridesium 305M is popular in decorative, industrial & art paints, wallpaper, leather, shoe heels/insole, and cosmetics Iridesium 305M is popular worldwide. However the most popular markets are the Middle East, Thailand, and Indonesia.

IRON

Pritty Iron family is comprised of mica coated with Iron Oxide. The different colour shades and effects are determined by the thickness of the Iron Oxide deposition. With more layers of Iron Oxide, the colour shade becomes more intense and reddish. Many unique and exciting colours are possible by combining Iron pearlescent pigments with other pearlescent pigment shades.

IRON

This product series is available in a variety of particle sizes from 5-25µm to 10-100µm. Depending on the particle size distribution the colours can vary in coverage and lustre. Technically this is a demanding product that requires precise process control in order to maintain colour consistency, especially for the colours 504, 524 and 534 which have the most layers of iron oxide.

COMMERCIAL INFORMATION •Iron is the 3rd most popular colour family, after Silver White and Gold Lustre •Iridesium 500 & Iridesium 502: Most popular for paint •Nacreium 9504, Nacreium 9502 & Nacreium 9522: very popular for Automotive OEM and refinish paint.

Pritty Iron Pricing:

Pritty’s Iron colours are in the mid-range price point compared to other Chinese producers. The quality also falls into the middle range.

Pritty Iron Strengths:

•Iridesium 500 is very similar to Iriodin 500 •Inventory of the popular items ( Iridesium 500, Iridesium 502, Nacreium 9522 & Nacreium 9500) •FDA compliant

Pritty Iron Weaknesses:

•Compare to Iriodin Iron family, Pritty Iron colours may not appear as saturated. •Pritty Iron family are not as opaque or do not have the hiding power of other colour families •Not so flexible to duplicate colour shade

COLOURED

Pritty Coloured family provides highly intense colour shades and are based on mica platelets coated with Titanium Dioxide and an additional layer of organic pigment. The combination of pearlescent pigments with organic pigments results in a more brilliant colour effect than a simple mixture of the two components.

COLO URED

Each Coloured pearlescent pigment contains of an absorption colorant deposited onto either a Mica substrate or an Interference mica platelet. When using an Interference base, the colorant is selected to reinforce the reflection colour of the Interference pigment. The result is a single dramatic reflection transmission colour.

COMMERCIAL INFORMATION Main Applications:

•Textile coatings (Main markets are Brazil, India and China). Quality control demand for this application is not high, but this application requires a bigger variety of colours with lower cost. •Cosmetic: Developing territories where there are no strict regulatory requirements. •Decorative Paint in certain regions. •Hobby and Craft Paint.

Pritty Coloured Strengths:

•Pritty’s quality control for the Coloured pigments is very good. It has no colour leaching or bleeding problems even after exposure to strong solvents.

Pritty Coloured Weaknesses:

•Not strategically important, production is based on “made to order”. •Less colour choices •All weaknesses of Organic pigments: Not FDA compliant, limited UV and temperature resistance.

MULTI-COLOUR

Pritty Multi-colour family pearlescent pigments display a special two-tone colour effect depending on the viewing angle. The multi-colour two tone effect is the result of coating an organic pigment on an interference pearl, with organic pigment mass tone differing from the reflection colour of the interference pigment.

This produces a special two-tone effect through the combination of light interference and absorption colour from the organic pigment. The interplay between background and highlight colours are very unique and cannot be duplicated by the simple combination of interference pigments and conventional colorants.

MULTICOLOUR

COMMERCIAL INFORMATION Applications:

•Decorative paint, especially in Middle East •Art and craft paint •Bicycle paint •Crayon •Nail Polish, or cosmetics in regions where FDA approval is not required •Latex rubber

Usage tips:

To achieve the maximum optically variable effect, the colour of the painted object should be a similar colour to the pearlescent pigment mass tone colour. Apply the pearlescent pigment with a clear media to the object.

Pritty Multi-Colour Strengths:

•Very strong flip-flop effect. •No colour leaching or bleeding problems even after exposure to strong solvents. •12 beautiful colours with 3 colour groups.

Pritty Multi-Colour Weaknesses:

•Not strategically important products, production is upon request, “Made to order”. •All weaknesses of Organic pigments: Not FDA compliant, limited UV and temperature resistance.

ANTIQUE

Pritty Antique family is produced with a very unique technology. It offers an intense black with a bright pearlescent/iridescence in 4 shades and 2 particle sizes.

There are two types of black pearls in the market:

•One type is made of Iron Oxide, which imparts reflectivity in a grey colour shade. •The other type is carbon black coated onto finished pearlescent pigments. It has a strong black colour however with a minimally reflective effect. Using its in-house technology, Pritty invented a perfect combination between blackness and brightness: Antique

ANTIQUE

Pritty Antique Signature colours:

Iridesium 4201 Iridesium 4211

Pritty Antique Strengths:

•Intense black with a strong sparkle effect. •Excellent for use in tint systems. It can be used to adjust the mass tone but change very little of the interference effect. •Solvent resistant, no colour leaching even after exposure to solvents. •Inventory of signature products: Iridesium 4201 & Iridesium 4211.

Pritty Antique Weaknesses:

•Limited hiding power. •Less interference effect, thus it is strongly recommended to use with other pigments in mass tone. •All weaknesses of Carbon Black: Not FDA compliant, limited UV and temperature resistance. •The density of this product is lower in comparison to other pearl pigments. Thus, when it is used in combination with other pearl pigments in water borne systems, after some time, the other pearls will settle out, while the Antique pigments will stay on the top. Therefore it is recommended that the coatings be stirred before use to ensure colour uniformity during the application process.

Caution: sometimes in waterborne formulations vigorous stirring leads

to incorporation of micro foam which can cause defects in the paint film upon cure.

CRISTAL METALLICS

•Less particle size choices. •Products with a particle size distribution of 10-60um are under development. It is expected to have large sparkle effect but with a smaller particle size. It is being developed specifically for printing ink applications.

MEGA SPARK

When the particle size is bigger than 500um, it gets difficult to deposit TiO2 on the substrate; this is previously a universal technical issue.

Pritty overcame this difficulty, and developed a new technology to coat TiO2 onto particles up to 1000um. Pritty Mega Spark comes in with 9 colours in 3 different colour families, with 2 different particle sizes: 100-700um & 2001000um
