Metal Coating CAS Number 9005 09 8 Carboxyl-Modified VC-Vac Copolymer Vinyl Resin VMCA
VMCA 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.

Application
VMCA grade 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.
