Vinyl Chloride / Vinyl Acetate Copolymer

Description

BDHH solution vinyl resin is a high molecular weight copolymer comprised of vinyl chloride and vinyl acetate. It is supplied as a powder.

Applications

Applications for BDHH solution vinyl resin include inks and overlacquers for vinyl substrates, strippable coatings, and a wide variety of clear and pigmented coatings for metal, wood, paper, film, foil, and fabric. Blends of BDHH solution vinyl resin and BDCH solution vinyl resin are used in air-dry industrial maintenance and marine coatings that can be recoated, even in cold weather.

Advantages

Good balance of chemical resistance, solubility, film strength, and thermoplasticity Adhesion to PVC

Low adhesion to metals for strippable applications

High film strength

Miscible with functionalized solution vinyls

Cited in FDA regulations for use in food-contact applications
