  • URETHANE (METH) ACRYLATE COMPOSITION AND SEAL MEMBER
    Publication number: 20110021695
    Abstract: A urethane (meth)acrylate composition includes a product of a reaction of a polyester polyol made from a polycarboxylic acid and a polyhydric alcohol, a polyisocyanate, and an active hydrogen-containing (meth)acrylate. Part of the polyhydric alcohol is a diol having a straight chain of 3 to 7 carbon atoms and a side chain on the straight chain. The polyisocyanate includes at least one of hexamethylene diisocyanate, diphenylmethane diisocyanate, hydrogenated diphenylmethane diisocyanate, and tetramethylene diisocyanate.
