FIELD: antiadhesive coatings on mold surfaces intended for molding products made of polymeric materials. SUBSTANCE: composition comprises, %: low-molecular weight polydimethylsiloxane rubber with symmetric end hydroxy groups or mixture thereof with polydimethylsiloxane liquid with trimethylsilyl groups, 0.8-8.5; combined cross-linking agent based on oligoorganohydride siloxane liquid, 1.0-10.7; tetrabutoxy titanium, 0.3-4.9; aminoorganotriethoxy silane, 0.1-0.5; and organic solvent, 85.0-95.0. Combined cross-linking agent is mixture of 0.6-9.7% of oligoorganohydride siloxane liquid with tetraethoxysilane, oligoethoxy siloxane or polyphenylethoxy siloxane. Oligoorganohydride siloxane liquid is essentially branched oligodimethylmethylhydride siloxane, oligodiethylethylhydride siloxane, oligodimethylmethylhydride ethoxy siloxane containing 10-55% of ethoxy groups, oligoethoxyhydride-2-ethylhexyloxyhydride siloxane or cyclic oligomethylhydride siloxane or cyclic oligomethylhydride siloxane. EFFECT: improved quality. 3 cl, 1 tbl
