Carboxyl-Modified Vinyl Chloride Vinyl Acetate resin (VMCH)

Equivalent to VMCH ex Dow

Property: 

It is carboxyl modified ternary copolymer of vinyl chloride, vinyl Acetate ester & maleic acid. Its high molecular resin. Molecular weight: 27000. It is soluble in correspondingly strong solvent & thinner composition, for example, 50% ketone 50% aromatic hydrocarbon, produce 25 28% (solid count) resin solution. As there is carboxyl -COOH in its molecule, VMCH has perfect adhesion power with the surface of metal, paper, carpentry, treated PE, PP, PET & PVC. It has very good chemical resistance, can resist acid, alkali, oil under normal temperature.

Application:

VMCH is mainly used for air-dry finishing paint, for example, repair paint, vessel paint, metal / can / beer paint, wood & glass coating, aluminum foil varnish, etc. Also can be used for making ink, adhesive (metal with metal, metal with PVC/PET), heat-seal packing paint (medicine packing, cigarette packing), glue for vitamine C packing, etc. It is complying with the standard of food & medical contact......
