Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
A method of bonding a silicone rubber to a non-silicone pressure sensitive adhesive comprising the steps of treating the surface of the silicone rubber to be bonded with a silicone adhesive, and thereafter applying a layer of the non-silicone pressure sensitive adhesive to the treated silicone rubber surface so as to obtain an immediate bond between said layer and said surface.
Claim 2
Independent Claim
61 words
A method of bonding a silicone rubber to a non-silicone pressure sensitive adhesive comprising the steps of treating the surface of the silicone rubber to be bonded with a silicone adhesive, and thereafter applying a layer of the non-silicone pressure sensitive adhesive to the treated silicone rubber surface so as to obtain an immediate bond between said layer and said surface.
Claim 3
Dependent Claim
27 words
A method according to claim 1 wherein the silicone adhesive is not cured with a curing agent prior to the application of the non-silicone pressure sensitive adhesive.
Claim 4
Dependent Claim
38 words
A method according to claim 2 wherein the non-silicone pressure sensitive adhesive is applied to the treated silicone rubber surface in the form of a carrier sheet having non-silicone pressure sensitive adhesive on both sides of said sheet.
Claim 5
Independent Claim
23 words
A method according to claims 1, 2 or 3 wherein the silicone adhesive is diluted prior to being applied to the silicone rubber.
Claim 6
Dependent Claim
14 words
A method according to claim 4 wherein the silicone adhesive is diluted with toluene.
Claim 7
Dependent Claim
26 words
A method according to claim 5 wherein the toluene solvent is dried from the treated silicone rubber surface prior to the application of the non-silicone adhesive.
Claim 8
Dependent Claim
20 words
A method according to claim 6 wherein the silicone adhesive is formulated to yield a high resin to gum ratio.
Claim 9
Independent Claim
88 words
A method of bonding a non-silicone pressure sensitive adhesive to silicone rubber weather stripping comprising the steps of treating the surface of the weather stripping with a solution of silicone adhesive dissolved in toluene, drying the toluene from the treated surface so as to yield a low tack or tack-free surface, and thereafter applying to the treated surface a carrying tape or strip having on both sides thereof a non-silicone pressure sensitive adhesive so as to obtain an immediate bond between said tape or strip and said surface.
Claim 10
Independent Claim
88 words
A method of bonding a non-silicone pressure sensitive adhesive to silicone rubber weather stripping comprising the steps of treating the surface of the weather stripping with a solution of silicone adhesive dissolved in toluene, drying the toluene from the treated surface so as to yield a low tack or tack-free surface, and thereafter applying to the treated surface a carrying tape or strip having on both sides thereof a non-silicone pressure sensitive adhesive so as to obtain an immediate bond between said tape or strip and said surface.
