Abstract
A primer composition that resists peeling and cracking is provided that includes an acrylic copolymer having a Tg of between −15 and −35° C.
Claims15
A paint primer composition for preparing a substrate to receive a paint layer, the paint primer composition comprising
- a pressure sensitive elastomeric resin, said resin comprising an acrylic-alkenyl copolymer comprising between 40 and 60% by weight acrylic monomer and between 40 and 60% by weight substituted-alkenyl monomer,
- wherein said acrylic-alkenyl copolymer is formed by a free radical copolymerization technique that randomly links the acrylic monomer and the substituted-alkenyl monomer,
- wherein said acrylic-alkenyl copolymer is a random copolymer having a Tg of between −10 and −45° C., and
- wherein the paint primer composition comprises greater than 75% and less than or equal to 85% by weight of the acrylic-alkenyl copolymer, a water content of at least 15%, and a VOC content of no greater than 75 g/l.
