Vinnol H 15/45 M Terpolymer of vinyl chloride, vinyl acetate and dicarboxylic acid Wacker Polyvinyl chloride (PVC) Polyvinyl acetate emulsions & derivatives (PVAc…) >> PVAc homopolymers Vinnol® H 15/45 M is a terpolymer of vinyl chloride (VC), vinyl acetate (VAc) and a dicarboxylic acid. Its main use is as a binder for surface coating com-pounds and printing inks. Vinnol® H 15/45 M is a physically drying binder that forms a film when the solvent contained in the formu- lation has evaporated. Like all VC copolymers, Vinnol® H 15/45 M is char- acterized by excellent toughness, permanent flexibil- ity, abrasion resistance, low swelling in the presence of water, and low gas permeability. On account of its carboxyl-group content, Vinnol® H 15/45 M adheres excellently to smooth substrates such as metals, particularly aluminium. The films also adhere well to glass and PVC, and to absorbent, po- rous substrates such as paper, cardboard, textiles and concrete. Films of Vinnol® H 15/45 M are highly resistant to water. They also show excellent resistance to oil, grease, dilute aqueous acids, alkalis and saline solu- tions. Aromatic hydrocarbons and chlorinated hydro- carbons cause them to swell to varying extents. Vin- nol® H 15/45 M is resistant to aliphatic hydrocarbons, such as white spirit, and to alcohols. Typical applications for Vinnol® H 15/45 M are: Metallic paints Paper and film coatings Heat-sealable lacquers Printing inks Masonry paints Terpolymer of vinyl chloride, vinyl acetate and a dicarboxylic acid. Provides very good toughness, permanent flexibility, abrasion resistance, low swelling in the presence of water, and low gas permeability. Offers very good adhesion to smooth substrates such as metals, particularly aluminium, to glass and PVC, and to absorbent, po-rous substrates such as paper, cardboard, textiles and concrete. Gives high resistance to water, oil, grease, dilute aqueous acids, alkalis and saline solutions, aliphatic hydrocarbons such as white spirit, and to alcohols.
