Carboxyl-Modified Vinyl Chloride Vinyl Acetate Terpolymer

Carboxyl-Modified Vinyl ChlorideVinyl Acetate Terpolymer EMP-VMA02 is white powder,ketone soluble with  colorless,transparent solution,and because of the carboxyl functional group,it   has excellent adhesion on  metal,especially on aluminum foil,the resin foil also  has a good adhesion on PVC, ABS, paper, textiles, beton,etc.Moreover, it offers a   desirable balance of chemical   resistance, solubility, diaphaneity, film strength, and   thermoplasticity. And it has excellent interbedded adhesion.

Competitor’s grades: DOW’s VMCA

Application:

EMP-VMA02 yields the good balance of solubility and   viscosity properties needed for high-build, air-dry maintenance finishes,and it  is often used to make  coatings and adhesives applications where higher solids  are desirable. It can be used in air-dry finishes, such as maintenance, marine, and  metal coatings, interbedded adhesive,aluminum foli varnish,UV surface  treatment,UV primer,thermal transfer adhesive, shoe adhesive, ink-jet and metal   inks,etc.

Package, storage and transportation:
