| abstract |
A debondable adhesive composition comprises (A) the hydrosilation reaction product of the reaction between the vinyl groups on 1,3,5,7-tetravinyl-1,3,5,7- tetramethylcyclotetra-siloxane and the terminal Si-H hydrogens on a silane or siloxane having terminal Si-H hydrogens, (B) a cross-linker for the hydrosilation reaction product, and (C) a metal catalyst and/or a radical initiator. In further embodiments, this invention is an assembly of a substrate and a carrier for the substrate in which the debondable adhesive composition is disposed between the substrates, and a method for fabricating that assembly. The debondable adhesive composition maintains its adhesion at temperatures of 300° C or greater, and is mechanically debondable at room temperature at a force less than 5N/25 mm. |
