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.
