vinyl resin solbin A

similar to VAGH, Solbin A
hydroxyl modified
terpolymer resin
of vinyl chloride
vinyl acetate and vinyl alcohol

solbin A
polyvinyl chloride polymer resin
TECHNICAL DATA SHEET Of
V A H vinyl resin
( 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 copolymer of vinyl chloride and vinyl acetate

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;
High glass transition temperature ( Tg) for blocking resistance and sandability
in wood sealers;
Resistance to water, alcohols and aliphatic hydrocarbons;
Adhesion to vinyl, cellulosics, PVC, ABS and properly treated PET and PE;
Heat-sealable;
FDA approved for food contact applications;
