It 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 adesirable balance of chemical resistance,solubility,diaphaneity,film strength,and thermoplasticity. And it has excellent interbedded adhesion.
Application:This 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.
