Coating raw material Vinyl Resin VAGH

1.Property:

It is hydroxyl modified ternary copolymer of vinyl chloride, vinyl acetate & vinyl alcohol. Molecular weight: 27000. It is soluble in correspondingly strong solvent & thinner composition, for example, 50% ketone & 50% aromatic hydrocarbon, producing 20% (solid count) resin solution. VAH has very good mutual solubility with other filmforming matter, for example, alkyd resin, polyurethane elastomer, carbimide acetate resin, epoxy polymer, melamine resin, urea – formaldehyde resin, etc. It is often used with other filmforming matter, to improve paint performance, reinforce the adhesive power, flexibility, tenacity, hardness & chemical resistance of paint.

2.Application:

VAGH is widely used for paint, industrial repair paint, vessel paint, top paint of wood, paper coating, metal, can and container paint, PVC / steel board adhesive, aluminizer varnish, magnetic tape adhesive, etc. It has good adhesive power with PET paper, PVC, ABS, treated PE & OPP. It is complying with the standard of food & medical contact.
