International ClassC09J 147/00AbstractA pressure-sensitive adhesive that can adhere aggressively to both polar and nonpolar substrates and has good internal strength at high temperatures is provided by heat or radiation curing a blend of an ethylenically-unsaturated -olefin polymer, a crosslinker having at least 2 hydrosilyl groups, and a hydrosilation catalyst. A preferred hydrosilane crosslinker has the formula ##STR1## wherein R is an alkyl group having 1-6 carbon atoms, and n' is a number in the range of 2 to 35.Other References
