Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
A method for controlling the release properties of an organic pressure-sensitive adhesive comprising: adding to the adhesive an additive comprising (i) a silicone pressure-sensitive adhesive, (ii) a silicone cross-linking agent, and (iii) a compatibilizing agent selected from the group consisting of an emulsifying agent compatible with both the silicone pressure-sensitive adhesive and the organic pressure-sensitive adhesive and a solvent capable of dissolving both the silicone pressure-sensitive adhesive and the organic pressure-sensitive adhesive.
Claim 2
Independent Claim
72 words
A method for controlling the release properties of an organic pressure-sensitive adhesive comprising: adding to the adhesive an additive comprising (i) a silicone pressure-sensitive adhesive, (ii) a silicone cross-linking agent, and (iii) a compatibilizing agent selected from the group consisting of an emulsifying agent compatible with both the silicone pressure-sensitive adhesive and the organic pressure-sensitive adhesive and a solvent capable of dissolving both the silicone pressure-sensitive adhesive and the organic pressure-sensitive adhesive.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein said silicone pressure-sensitive adhesive is a mixture of silicone resin and silicone fluid.
Claim 4
Dependent Claim
16 words
The method of claim 1 wherein said silicone cross-linking agent is selected from peroxide cross-linking agents.
Claim 5
Dependent Claim
31 words
The method of claim 3 wherein said silicone cross-linking agent is selected from the group consisting of diaroyl peroxides, dialkyl peroxides, alkyl aralkyl peroxides, alkyl aroyl peroxide and alkyl acyl peroxide.
Claim 6
Dependent Claim
30 words
The method of claim 3 wherein said peroxide cross-linking agent is present in an amount ranging from about 0.1 to about 3% by weight based on silicone pressure-sensitive adhesive content.
Claim 7
Dependent Claim
21 words
The method of claim 1 wherein said silicone cross-linking agent is selected from alkoxy silane cross-linking agents with a cross-linking catalyst.
Claim 8
Dependent Claim
24 words
The method of claim 6 wherein said silicone cross-linking agent is selected from the group consisting of methyltrimethoxy silane, gamma-aminopropyltrimethoxy silane and triethoxy silane.
Claim 9
Dependent Claim
31 words
The method of claim 6 wherein said alkoxy silane cross-linking agent is present in an amount ranging about about 1 to about 10% by weight based on silicone pressure-sensitive adhesive content.
Claim 10
Dependent Claim
47 words
The method of claim 1 wherein said organic pressure-sensitive adhesive is selected from the group consisting of milled natural rubber, styrene-butadiene rubber, butyl rubber, butadiene-acrylonitrile rubber, polyvinyl ether rubber, polyacrylate ester rubber and said emulsifying agent is a primary or secondary amine salt of an organic acid.
Claim 11
Dependent Claim
23 words
The method of claim 9 wherein said primary or secondary amine salt of an organic acid is the morpholine salt of undecylenic acid.
Claim 12
Dependent Claim
21 words
The method of claim 1 wherein said organic pressure-sensitive adhesive is an acrylic rubber and said emulsifying agent is an ethoxylate.
Claim 13
Dependent Claim
12 words
The method of claim 11 wherein said ethoxylate is an aryl ethoxylate.
Claim 14
Dependent Claim
12 words
The method of claim 1 wherein the compatibilizing agent is a solvent.
Claim 15
Dependent Claim
13 words
The method of claim 1 further comprising applying the adhesive to a substrate.
Claim 16
Dependent Claim
10 words
The method of claim 14 further comprising drying the adhesive.
