Terpolymer of vinyl chloride and vinyl acetate and vinyl alcohol.

Vinyl resin terpolymer is similar with VAGH of Dow chemical

Vinyl resin terpolymer ---Copolymer resin B-VAGH

Description: It is a high molecular weight, hydroxyl-functional, partially-hydrolyzed B-VAGH resin. It is a hydroxyl modified Terpolymer of vinyl chloride and vinyl acetate and vinyl alcohol.

Introduction: It is a cross linkable 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, 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 ink, 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:

Cross linkable with amino resins or polyisocyanates;       Compatible with many other generic resins;

Resistance to water, alcohols and aliphatic hydrocarbons;  FDA approved for food contact applications;

High glass transition temperature ( Tg) for blocking resistance and sandability in wood sealers;

Adhesion to vinyl, cellulosics, PVC, ABS and properly treated PET and PE;

Recommendation for Resin Dissolving Procedure:

Add weak solvent such as ethyl acetate or toluene into the blending tank first with agitation. Slowly put terpolymer resin such as B-VAGH into the above solvents with agitation. Put strong solvents last, such as MEK or MIPK  If possible, heating and keeping temperature at 60-70 degree C, which will help the dissolving process, otherwise, takes longer time. Resin concentration may vary with client's formulation
