customize your products VINNOL® is the brandname for a system of vinyl chloride co- and terpolymers that are used as surface coating resins in various applications such as: • Heat-sealable and heat-seal-resistant coatings for aluminum foil • Printing inks • Industrial coatings WACKER offers a sophisticated portfolio of VINNOL® resins in order to meet customers’ needs. With a range of different polymer resins that are fully compatible with each other, it is possible to tailor the relevant properties of heat-sealing lacquers, inks and coatings.
VINNOL® is a registered trademark of Wacker Chemie AG.
By choosing the right combination of VINNOL® grades, our customers are able to adjust the viscosity of a coating or ink according to the individual application requirements. At the same time, it is possible to modify the pigment-wetting property or the resin-dispersion time. Heat-sealing lacquers can be customized by adapting the sealing temperature, seal-bond strength or the adhesion to a specific substrate.
Key Advantages of VINNOL® •H igh toughness and permanent flexibility • Superior abrasion resistance • Outstanding water and chemical resistance • Inherent flame retardance • Excellent solubility and ease of processing • Wide formulation range • Odorless and tasteless
In addition to its comprehensive portfolio, WACKER offers you extensive services, ranging from product recommendations and formulation guidelines to assistance in producing and applying surface coatings with VINNOL®. Just contact us! We will be glad to support you.

Discover a unique Portfolio VINNOL® resins are available in three major product categories: VINNOL® Surface Coating Resins without Functional Groups VINNOL® resins without functional groups are copolymers of vinyl chloride and vinyl acetate. They are available in different molar compositions and a broad molecular weight range.
VINNOL® Surface Coating Resins with Hydroxyl Groups VINNOL® resins with hydroxyl groups are available in two different product types. VINNOL® E/A grades are copolymers and terpolymers of vinyl chloride, hydroxy acrylate and, in the case of VINNOL® E 22/48 A, dicarboxylic acid ester. The other product type, VINNOL® H 5/50 A, is a terpolymer of vinyl chloride, vinyl acetate and vinyl alcohol.
VINNOL® Surface Coating Resins with Carboxyl Groups VINNOL® surface coating resins with carboxyl groups are terpolymers of vinyl chloride, vinyl acetate and dicarboxylic acids. These grades can be identified by an "M" in the product name. They provide excellent adhesion, particularly to metal substrates. Adhesion to mineral substrates is also enhanced.
VINNOL® Non-Functional Grades

The hydroxyl groups provide strong adhesion to various plastic substrates as well as to metal and wood. Hydroxy-modified VINNOL® resins are particularly compatible with other coating resin classes such as alkyd, epoxy, urea, ketone, melamine, phenolic, acrylic and isocyanate resins. Additionally, the hydroxy functionality permits crosslinking reactions for coating systems with outstanding chemical and thermo-mechanical resistance as well as improved surface hardness and abrasion resistance.

WACKER uses two different types of polymerization processes for VINNOL® resins. Suspension Polymerization VINNOL® H resins are produced by a suspension process and are best used in transparent coatings. Furthermore, they offer very high water and chemical resistance. Emulsion Polymerization VINNOL® E resins are produced by an emulsion process and are unique to the market. They exhibit excellent pigmentwetting properties, which renders them ideal for pigmented systems. VINNOL® grades are available in different molar compositions and molecular weights, which affects the solubility and the physicochemical properties of the coatings.
Influence of the Molecular Weight As the molecular weight (K value, degree of polymerization) rises, the solution viscosity increases. So do the mechanical strength and softening range of the coating. Influence of the Vinyl Acetate Content The polymer’s vinyl acetate content increases the flexibility and lowers the softening temperature of VINNOL®-based coatings. Increasing the vinyl acetate content leads to higher solubility in various solvents and lower solution viscosities. Vinyl chloride-vinyl acetate copolymers, with a very high vinyl acetate content, such as the unique VINNOL® H 40 series, are frequently used to enhance the flexibility of coating systems. For heat sealing applications, VINNOL® H 40 resins enable customers to significantly lower the sealing temperature.
How to Read the Product Names Vinyl Acetate Functional Content Group
VINNOL ® H 15/45 M Polymerization K Value Process
Vinyl Acetate Content: A higher vinyl acetate content reduces solution viscosity and the coating-softening range while increasing coating flexibility.
Functional Group: No letter = No functional group M = Carboxyl group A = Hydroxyl group
Polymerization Process: H = Suspension polymerization E = Emulsion polymerization
K Value: Molecular weight / viscosity. A higher K value increases solution viscosity, mechanical strength and the coatingsoftening range.
