摘要

The composition which predominantly consists of heat-curable, polyol-modified polysiloxane A and. based on polysiloxane A, 0.05 to 4% by weight of a linear siloxane B which is reactive with said siloxane A, the modified polysiloxane A being obtainable by reacting a polysiloxane A1 of the general formula …… (OR<1> = alkoxy group derived from primary or secondary alcohol having 1 to 4 carbon atoms,… R<2> = alkyl and/or phenyl radical,… a = 1 to 1.5,… b = 0.1 to 0.3… with a polyhydric alcohol A2, characterised in that the polyhydric alcohol A2 used is a polyol containing ester groups and of the general formula …… obtainable by esterifying 1 mol of a dicarboxylic acid HOOC-R<7>-COOH with 2 mol of an alcohol of the formula R<6>OH, in which the R<6> radicals in the molecule are identical or different and denote the group …… in which R<7> is an alkylene, cycloalkylene or phenylene group, and the polyol containing ester groups must have at least three hydroxyl groups.
