Vinyl Chloride and Vinyl Acetate Copolymers MLC-14-55
New grade Vinyl Chloride and Vinyl Acetate Copolymers MLC-14-55:It is white powder,ester soluble with colorless,transparent solution, and it has perfect balance on film-formation ,solvent release property ,high chemical resistance ,dissoluvability,color contrast property,paint film intensity and thermoplasticity.etc.And it has lasting flexibility,abrasive resistance,low expansion rate and low water and gas permeability, therefore, it can be oil resistivity,grease resistance,dilute acid resistance,alkali resistance,salt resistance and alcohol resistance. It is the binders with physical property drying with the film formation after the solvent volatilization in the system.
MLC-14-55 Vinyl Resin Quality standard (XHQB-6).
