EMULSION-BASED HIGH RELEASE ADDITIVE FOR RELEASE SHEET, EMULSION COMPOSITION FOR RELEASE SHEET, AND MOLD RELEASE SHEET

摘要

It solves the problems, such as: lotion base weight release additives, release sheet is used for provide, it is influenced with excellent high release and expected power of releasing again can be ensured by adding on a small quantity and its in curable silicone compositions for release sheet, peeling force with less time deterioration, and used after solidifying with emulsion compositions release sheet and thin slice. ;SOLUTION: it is 100-300 that emulsion base, which re-releases its average degree of polymerization of (A-1) by dehydration polydiorganosiloxanepolyurea that generation condensation reaction obtains between condensation product (one) obtained from additive release sheet is dispersed in water,000, and there is at least one hydroxyl or hydrolyzable group per molecule; Mainly by (SiO4/2) unit (R3SiO1/2) unit, (wherein R independently indicates 1-12C or 2-6C alkenyl monovalent hydrocarbon groups to (A-2) polyorganosiloxane resin, respectively whether there is or not aliphatic unsaturated bonds), have than the 0. of (R3SiO1/2) to (SiO4/2) unit cell6-1.The 2. of the hydroxyl and hydrolyzable base of 2 moles of % and total amount1 mass % is more than and less than 10.0 mass %. Therefore, additive, which is added in composition, discharges thin slice, such as paper or release film, and on a variety of substrates of application, is then solidified, thus there is silicone cure film high peeling force can be obtained. ;COPYRIGHT:(C) 2014, JPO& INPIT
