Product description: VINNOL® H 30/48 M is a carboxylate-containing terpolymer of approx. 70 wt. % vinyl chloride (VC), approx. 29 wt. % vinyl acetate (VAc) and approx. 1 wt.% dicarboxylic acid. Its main use is as a binder for surface coating compounds and printing inks.

Properties: VINNOL® H 30/48 M is a thermoplastic, physically drying binder that forms a film when the solvent contained in the formulation has evaporated. Like all VC copolymers, VINNOL® H 30/48 M isextremely tough, showing permanent flexibility, abrasion resistance, little tendency to swell in the presence of water and low gas permeability. It is also highly resistant to oil, grease, dilute aqueous acids, alkalis and saline solutions, as well as to aliphatic hydrocarbons, such as white spirit, and alcohols.

Special features: Because of its content of carboxyl groups, VINNOL® H 30/48 M adheres excellently to metal surfaces. VINNOL® H 30/48 M is a high vinyl acetate containing copolymer. It is therefore especially suitable as a cobinder for formulating flexible VINNOL®-paint and printing ink formulations. It is also highly recommended to reduce the sealing temperature in VINNOL®-based heat sealing lacquers. The solubility in various monomers enables to use VINNOL® H 30/48 M as an additive in solvent-free 100% systems to improve adhesion and pigment wetting or to reduce shrinking. It can also be used as a reactant or co-binder in two pack systems. For example, it may be crosslinked with isocyanates, epoxy or melamine resins.

Application: Typical applications for VINNOL® H 30/48 M:

• Heat-sealable lacquers
• Metallic paints
• Paper and film coatings
• Printing inks
• Masonry paints
