Product description: VINNOL® E 22/48 A is a hydroxyl-containing copolymer of approx. 75 wt.% vinyl chloride (VC) and approx. 25 wt.% carbon acid esters. Its main use is as a binder for surface coating compounds and printing inks.

Properties: VINNOL® E 22/48 A 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 22/48 A 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: VINNOL® E 22/48 A contains approx. 1.8 wt. % free hydroxyl groups and can therefore 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® E 22/48 A:

• Magnetic tape coatings
• Primers
• Intermediate coatings
• Two-pack coating systems
• Baking finishes
• Adhesives
• Printing inks
