Vinyl Chloride and Vinyl Acetate Copolymers MLC-14-62
New grade MLC-14-62:It is white powder,ester soluble with colorless,transparent solution, and it has very good dissoluvability,film-formation ,solvent release property ,chemical resistance ,color contrast property and after-tack resistance.And it has lasting flexibility,abrasive resistance,low expansion rate and low water and gas permeability, therefore, Vinyl Chloride and Vinyl Acetate Copolymers can be oil resistivity,grease resistance,dilute acid resistance,alkali resistance,salt resistance and alcohol resistance.It also is binders with physical property drying with the film formation after the solvent volatilization in the system.
.
MLC-14-62 Vinyl Resin Quality standard (XHQB-6).
