Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
62 words
A method of improving the bonding of crosslinked ethylene-vinyl acetate to crosslinked silicone rubber which comprises admixing the ethylene-vinyl acetate with a silane bonding agent selected from the group consisting of gamma methacryloxypropyl trimethoxysilane, vinyl triethoxysilane, ##SPC2## and (CH 3 O) 3 Si(CH 2 ) 3 Cl prior to adhering the ethylene-vinyl acetate to the silicone rubber and crosslinking the resulting laminate.
Claim 2
Independent Claim
62 words
A method of improving the bonding of crosslinked ethylene-vinyl acetate to crosslinked silicone rubber which comprises admixing the ethylene-vinyl acetate with a silane bonding agent selected from the group consisting of gamma methacryloxypropyl trimethoxysilane, vinyl triethoxysilane, ##SPC2## and (CH 3 O) 3 Si(CH 2 ) 3 Cl prior to adhering the ethylene-vinyl acetate to the silicone rubber and crosslinking the resulting laminate.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said silane bonding agent is used in an amount of about 0.1 to 25 parts per hundred parts ethylene-vinyl acetate resin.
