Pressure-sensitive adhesive based on ethylenically-unsaturated alpha-olefin polymer cured with hydrosilane

摘要

A 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 alpha -olefin polymer, a crosslinker having at least 2 hydrosilyl groups, and a hydrosilation catalyst. A preferred hydrosilane crosslinker has the formula wherein R is an alkyl group having 1-6 carbon atoms, and n' is a number in the range of 2 to 35.
