Hydroxyl Modified Terpolymer Resin
Of vinyl chloride vinyl acetate and vinyl alcohol
V A H (similar to VAGH of Dow Chemical)

Description: It is a high molecular weight, hydroxyl-functional, partially-hydrolyzed vinyl chloride/vinyl acetate resin, it is powder form. It is a hydroxyl modified terpolymer of vinyl chloride, vinyl acetate and vinyl alcohol.

Introduction: It is a crosslinkable with amino resins and polyisocyanates and is also compatible with a wide variety of resins including alkyds and acrylics. This resin has good adhesion to vinyl, cellulosic and treated polyester and PE substrates. It imparts good sandability in vinyl/alkyd/urea wood sealers. It is cited in FDA regulations for use in food contact applications and is also heat-sealable.

Application: It was widely be used in the industries of paint, coating, industrial repair paint, marine paint, wooden surface paint, paper paint, metal decorate paint, container paint, adhesive for PVC/ armor plate, adhesive for tape etc.

Typical applications:
Flexible packaging and binder in Magnetic Tape
General Metal and Container Coatings
Wood Finishes and Paper Coatings
Industrial Maintenance
Marine and Maintenance Coatings

Features:
Crosslinkable with amino resins or polyisocyanates;
Compatible with many other generic resins;
