Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A laminate comprising two surfaces spaced apart by an adhesive composition and held in that relationship by a bond between said surfaces and said adhesive, which comprises a mixture on a weight basis of an acrylic adhesive composition, 1 to 10 percent of an organic tin compound and 1 to 10 percent of an organic silicone of the formula ##STR2## where R 1 and R are alkyl, cycloalkyl and aryl groups with the proviso that R 1 and R groups can be the same or different and N has a value of about 10 to 10,000.
Claim 2
Dependent Claim
96 words
A laminate comprising two surfaces spaced apart by an adhesive composition and held in that relationship by a bond between said surfaces and said adhesive, which comprises a mixture on a weight basis of an acrylic adhesive composition, 1 to 10 percent of an organic tin compound and 1 to 10 percent of an organic silicone of the formula ##STR2## where R 1 and R are alkyl, cycloalkyl and aryl groups with the proviso that R 1 and R groups can be the same or different and N has a value of about 10 to 10,000.
Claim 3
Dependent Claim
13 words
The laminate of claim 1 wherein the adhesive is a pressure sensitive adhesive.
Claim 4
Dependent Claim
15 words
The laminate of claim 1 wherein the R 1 group of the silicone is methyl.
Claim 5
Dependent Claim
20 words
The laminate of claim 1 where the two surfaces are faces of a slit in a cellular foamed insulation member.
Claim 6
Dependent Claim
23 words
The laminate of claim 4 wherein the adhesives are on each face of the slit and held apart by a removable release member.
Claim 7
Dependent Claim
57 words
The laminate of claim 1 wherein the two surfaces containing the adhesive are initially positioned on each side of a slit in an insulation member and the adhesive is brought into contact by moving one surface with its adhesive across said slit to rest said adhesive on said surface in juxtaposition on adhesive on the other surface.
