Process for preparing a laminated composite of condensation type silicone rubber and polyurethane by induce surface reconstruction
Induced surface reconstruction of silicone rubber by blending silicone gel reactants with a modified and curing with a mold having high critical surface tension was used to improve the adhesion of chemically inert silicone rubber to polyurethane. The modifier has the following formula wherein m=25&#732;50; R1, R2, R3, R4, R11 and R12 independently are alkyl; R&#8242; is R or OR, wherein R is a polymer backbone having a molecular weight of 1000&#732;20000. The mold is formed with a material having a critical surface tension greater than that of a polymer having a repeating unit of said R.
