Description
SA-28 solid acrylic resin is a copolymer of methacrylates, which
has the characteristics of high adhesion, good flexibility, low
shrinkage and good durability. It is widely used in aluminum heat
sealing varnish, cardboard ink, metallic paint, etc.
SA-28 copolymer of methacrylates is soluble in alcohols and other
ketones, esters, aromatics, chlorinated solvents and other organic
