Abstract:
A release composition comprising(A) the reaction product of: 1) REhSi(ORA)4-h; 2) RviiSi(ORB)4-i; 3) a condensation catalyst; and 4) water where RE is an oxirane or epoxide containing radical having from two to forty carbon atoms, Rvi is selected from the group consisting of two to forty carbon atom terminal olefinic monovalent hydrocarbon radicals, RA is selected from the group consisting of one to forty carbon monovalent hydrocarbon radicals; RB is selected from the group consisting of one to forty carbon monovalent hydrocarbon radicals, where h varies from 1 to 3 and where i varies from 1 to 3 and(B) a curable alkenyl silicone having the formula MviaTbDcMd â€ƒwhere Mvi=R3-pR1pSiO1/2, where R is selected from the group consisting of one to forty carbon monovalent hydrocarbon radicals and R1 is selected from the group consisting of two to forty carbon atom terminal olefinic monovalent hydrocarbon radicals, where p ranges from 1 to 3; T=R2SiO3/2 where R2 is selected from the group consisting of R and R1; D=R3R4SiO2/2 where R3 and R4 are each independently selected from the group consisting of R and R1; and M=R3SiO1/2 where each R is as previously defined and is independently selected; wherein a and b have values ranging from 2 to 5, c is an integer ranging from about 50 to about 1,000 and d has a value ranging from 0 to about 0.5.
