Patent ID: 7144937

Claim:
A sealant composition comprising a sealant; and an adhesion promoter containing (1) an adhesive resin in an amount of about 0.1% to about 15% by weight, based on the weight of the sealant in the sealant composition; and (2) an ester having formula II, III, IV or a combination of any two or more of said esters in an amount of about 0.1% to about 15% by weight, based on the weight of the sealant in the sealant composition: wherein n=3–24, and R 3 and R 4 , same or different, are a C 6 –C 24 alkyl radical, straight chain or branched, saturated or unsaturated containing 1 to 3 carbon-to-carbon double bonds; wherein R 5 and R 7 , same or different, are a C 3 –C 24 hydrocarbon chain, straight chain or branched, either saturated or having 1 to 6 carbon-to-carbon double bonds; R 6 and R 8 , same or different, are C 3 –C 24 alkyl radical, straight chain or branched, saturated or unsaturated containing 1 to 3 carbon-to-carbon double bonds; and R 10 and R 11 , same or different, are a C 3 –C 24 , saturated hydrocarbon chain, straight chain or branched; or an unsaturated C 3 –C 24 , hydrocarbon chain, straight chain or branched, having 1 to 6, carbon-to-carbon double bonds; wherein R 12 , R 14 and R 18 , same or different, are a C 3 –C 24 hydrocarbon chain, straight chain or branched, either saturated or having 1 to 6 carbon-to-carbon double bonds; R 13 , R 15 and R 19 , same or different, are a C 3 –C 24 alkyl, straight chain or branched, saturated or unsaturated containing 1 to 3 carbon-to-carbon double bonds; and R 16 , R 17 and R 20 , same or different, are a C 3 –C 24 saturated hydrocarbon chain, straight chain or branched; or unsaturated C 3 –C 24 hydrocarbon chain, straight chain or branched, containing 1 to 6 carbon-to-carbon double bonds.
