Product description: VINNOL® E 15/45 M TF is a carboxylate-containing terpolymer of approx. 84 wt. % vinyl chloride (VC), approx. 15 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® E 15/45 M TF is a thermoplastic, physically drying binder that forms a film when the solvent contained in the formulation has evaporated. Like all VC copolymers, VINNOL® E 15/45 M TF is extremely 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: By virtue of its carboxyl content, VINNOL® E 15/45 M TF adheres excellently to metal surfaces as well as on polymeric substrates like polyester or cellophane. It can also be used as a reactant or co-binder in twopack systems. For example, it may be crosslinked with isocyanates, epoxy or melamine resins.

Application: Typical applications for VINNOL® E 15/45 M TF:

• Metallic paints
• Paper and film coatings
• Printing inks
• Masonry paints
