Adhesives
Edging specialist, Ostermann, supplies a high-quality selection of hotmelt adhesives for mechanical edging processing. But how do customers go about finding the right product? Here, the Ostermann experts inform on important basics and provide useful tips ...
Filled EVA adhesive is a ‘classic’ in furnituremaking and interior design. It is distinguished by its easy handling, a fine bondline and a lower tendency for stringing.
With unfilled EVA hotmelt adhesive, joints become thinner – you need less glue but higher feed speeds. To find the right hotmelt adhesive, use the filter function in the Ostermann online shop. This way, you can quickly narrow down the type of adhesive, colour, filler, manufacturer, feed speed of your machine or the type of container, and reach the best product for your individual requirements.
Waterproof? Choose PUR!
PUR adhesives are suited for rather difficult bonding tasks, for example in kitchen and bathroom furniture. The chemical cross-linking induces particularly high heat and water resistance. Moreover, the adhesive’s bonding strength and the chemical resistance of the joint are higher than with EVA adhesives. Glue consumption is lower and you can achieve a very thin joint, equalling a visually flawless bondline. If the machine is perfectly adjusted, you can even achieve the often sought ‘invisible bondline’ with PUR.
No fear of PUR
Many processors have considered changing to PUR for a while, but the need to clean their edgebanding machine after an application of PUR adhesive makes them hesitate. There is a video tutorial on this exact topic on the Ostermann website, www.ostermann.eu. It shows in detail the necessary steps to change from EVA to PUR hotmelt adhesive and back.
PUR hotmelt adhesives from Ostermann’s own brand, REDOCOL, are particularly attractive – there is a large selection of high-quality products at economical prices. In addition, Ostermann supplies matching products to clean the

If resistance to heat and water is needed, PUR hotmelt adhesive is the product of choice
The knottec system from Power Adhesives is the fastest way to repair knot defects and other forms of deep wood damage.
Knots and deep scratches in wood can be fi lled quickly and easily using a special knot-fi lling adhesive that is applied with a 12mm tec hotmelt glue gun. The system also includes a pair of handy heat-sink blocks that can be used to create a ‘form’ around any knot holes that go through, or are on the edge of, areas of wood that need repair.
Once the damaged area has been fi lled, the knottec knot-fi lling adhesive takes just minutes to cool before the excess can be trimmed with a fl ush plane tool, such as the Mouseplane. The repaired area can then be sanded, painted or treated as normal, achieving a high-quality fi nish to the restored wood.
Ideal for repairing furniture
Because it is so tough, knottec is suitable for making repairs to wood fl ooring, doors, window frames, furniture and more. This knotfi lling adhesive is also available in 15 different colours to help users achieve the best colour match possible.
This unique repair process for knot defects and other forms of deep wood damage can now be used with the fully portable b-tec 308 and 808 glue guns.
The compact b-tec 308, and the larger, higher output b-tec 808 battery-powered glue guns both feature an eco-mode setting that will signifi cantly extend the battery life for any given battery size.
B-tec 308 users can work for up to five hours, uninterrupted, while b-tec 808 users can work for up to 3.5 hours.
The b-tec cordless glue guns have been designed to use the widely available Ryobi 18V ONE+ range of lithium+ batteries and chargers.
When used with a Badaptor battery adaptor, customers can use their 18V DeWalt, Makita, Milwaukee, Bosch Professional, Ridgid or AEG battery with their b-tec cordless glue gun, or in any tool that takes a Ryobi 18V battery.
Power Adhesives offers a choice of two additional mains-powered 12mm glue guns for use with the knottec system – the light industrial tec 305 and the professional tec 820 – as well as the Mouseplane tool for trimming away excess glue. Cost-effective knottec kits, containing everything users need to get started in a practical carry case, are also available.
Power Adhesives manufactures its expansive range of industrial glue guns and high-performance shaped hotmelt adhesives at its Basildon plant in the UK. Its products are sold through a network of specialist distributors around the world.
A continuous programme of research and development ensures that the company continues to meet the ever-changing needs of industry, with innovative solutions like the knottec system.

The Kenyon Group supplies some of the best hotmelt adhesives on the market, especially when it come to edgebanding, which has been the company’s focus point for many years.
As new products come onto the market, one adhesive range has remained unchanged, standing the test of time and for good reasons. Offering both EVA and PUR technologies, Henkel’s Technomelt Dorus HKP range of hotmelt adhesive cartridges provides exceptional gluing performance and an easy-to-use option for HolzHer edgebanders. Having been specifically designed for Holz-Her edgebanders, they are compatible for use on all of the machines with feed-rates from 10m/min.
PUR/EVA cartridge adhesives for Holz-Her edgebanders
With more and more companies choosing PURHM adhesives for the many performance benefits they provide, Technomelt Dorus HKP27 PUR has quickly become a key choice for Holz-Her edgebanders, making it the go-to adhesive for kitchen, door, cubicle and bathroom furniture manufacture, allowing a high degree of moisture and heat resistance to be achieved. Technomelt Dorus HKP27 PUR also provides many additional benefits such as cold flexibility resistance, high initial strength and very tight joints, which can achieve invisible glue lines.
Technomelt Dorus HKP 20 and 25
Where high moisture or heat resistance is not required, for example bedroom furniture, EVA adhesives are the ideal choice for companies. The Technomelt Dorus HKP range has an exceptional offering with Technomelt Dorus HKP20 and Technomelt Dorus HKP25 – between these two all the bases are covered, helping achieve the production line finishes that are expected in today’s competitive markets.
Technomelt Dorus HKP 20 – Unfilled, transparent, EVA edgebanding hotmelt for Holz-Her equipment allows for thinner coat weights and high glue mileage, making this a premium EVA grade.
Technomelt Dorus HKP 25 – Filled EVA edgebanding hotmelt for Holz-Her equipment, is available in a range of colours (natural, white, brown and black), so no matter what edging colour is decided on, the user be assured that the adhesive options available will have it covered.
Technomelt Cleaner 2 – Blue
cleaning agent is suitable for all polyurethane (PUR) hotmelts in the uncured state.
Holz-Her edgebanders are not just limited to cartridge adhesives. With clever additions such as the hopper system which can be attached to the machines, it allows for the use of both EVA and PUR granules. This clever and innovative addition provides companies access to other high-performance grades from the range, such as Technomelt Dorus KS 351 unfilled edgebanding or Technomelt PUR 270/7 G (granules), both of which are recognised for their clean running and outstanding gluing performance. The Henkel name is quite rightly associated with quality and market leading technologies, and this does not purely apply to their adhesives, but also to their extensive range of hot melt cleaners, which cover everything from surface cleaning through to thorough system/application equipment cleaning.
Given that an effective cleaning process can make all the difference to meeting deadlines, maximising output and achieving daily goals, Kenyon Group is here to help set businesses on the right path and ensure they are getting the most out of their day.
Henkel Technomelt 270/7 PUR Granules
Having recognised the gap in the market, Henkel made the decision to manufacture its Premium PUR grade – the tried, tested and proven Technomelt 270/7 – in a granular form, allowing companies to run the PUR adhesive on their existing edgebanding lines without the outlay and hassle of purchasing new equipment.
This has proved very successful and provided easy access to PUR technology for every company, opening the door to what can be achieved with PUR and increasing the quality of the finished goods.
Henkel PUR granules make gluing easy, with their ability to be used on customers’ existing edgebanding lines, convenient, flexible and costsaving advantages.
Technomelt PUR 270/7 is supplied in 12kg cartons, with each carton containing 16 x 750g individual foil packs of PUR granules.
This provides a cost-effective option for middle- to low-volume users, by allowing them to control the amount of adhesive being used against their scheduled volume of work.
Foil packs that have been opened can be wrapped and taped and will be good for around 48 hours, reducing wastage and saving money.
PUR adhesives and good housekeeping
When it comes to cleaning, as with any PUR adhesive, a waxbased cleaner such as Technomelt Cleaner 2) is required to prevent the adhesive from cross-linking and curing within the machine. With the larger 2kg blocks, normally one or two cleaning slugs will have to be purged through the system, to clean it down of any remaining PUR within it.
Henkel’s PUR granules offer the ability to gauge the adhesive level within the glue pot throughout the day and run it down towards the end of the shift, meaning there is very little PUR adhesive left in the glue pot prior to cleaning.
Use the recommended cleaner for Henkel PUR granules (Technomelt Cleaner 4), which is supplied in a blue granule form, and can be put directly into the glue pot. Normally half to a full cup will be sufficient. This reduces cleaning times and allows for a quick start-up the following morning.
