SILICONE RELEASE COMPOSITIONS |
摘要 |
A release modifier for silicone release compositions comprising a MQ resin consisting essentially of units of the formulae SiO2 (Q) and R3SiO1/2 (M) wherein R denotes a monovalent hydrocarbon group having up to 3 carbon atoms, a hydrogen atom, an alkenyl group of the formula -R1CH=CH2 or an oxyalkenyl group of the formula -OR'CH=CH2, wherein R' denotes an alkylene group of from 4 to 12 carbon atoms, provided there is at least one group -R'CH=CH2 or one group -OR'CH=CH2 present per MQ molecule and that no more than 50% of all M units have such groups. Also claimed is a solventless release composition based on siloxanes having SiH groups and a catalyst in addition to the release modifier. |
