摘要:
Disclosed herein are coating compositions that may include at least one urethane (meth)acrylate oligomer having a molecular weight between about 2,000 g/mol and about 50,000 g/mol and at least one cycloaliphatic (meth)acrylate. The coating compositions may also optionally include at least one photo-initiator, adhesion promoter, pigment, dye and/or plasticizer. The coating compositions may be hardened, after application, by curing by exposure to radiant energy, by exposure to electron beam radiation, by exposure to heat, by exposure to chemicals and combinations thereof. Upon hardening, the coating composition typically has two phases, a soft phase which has a Tg between −50° C. and 0° C. and a hard phase which has a Tg between 60° C. and 120° C. Methods of using the coating compositions are also described.
