ABSTRACT:
A release agent composition which manifests almost no silicone migration and a very low slickness while nevertheless having a low release value is achieved by means of a release agent composition which is based on a methylalkenylpolysiloxane, an alkylhydrogenpolysiloxane crosslinker for the methylalkenylpolysiloxane, an organopolysiloxane containing monovalent hydrocarbon groups which lacks aliphatically unsaturated bonds and which contains 6 to 18 carbon atoms which functions to lighten the releaseability of the cured film, to check silicone migration, and to reduce the slickness, and a catalytic quantity of a platinum-type catalyst.
