METHOD FOR REDUCING SURFACE-TACKING PROPERTY OF CURED PRODUCT OF SILICONE RUBBER, LIQUID SILICONE RUBBER COMPOSITION FOR SEALING SEMICONDUCTOR, SILICONE RUBBER-SEALED SEMICONDUCTOR DEVICE AND METHOD FOR PRODUCING THE SEMICONDUCTOR DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a method for reducing surface-tacking property while stabilizing the characteristics of a cured product of a silicone rubber in a flexible rubber type as an elastomer with time. PSOLUTION: The method for reducing the surface-tacking property of the cured product of the silicone rubber comprises covering the surface of the cured product of a curable silicone rubber composition having 1.0 molar ratio of a hydrogen atom bound with a silicon atom to an alkenyl group bound with the silicon atom in the composition, and providing the cured product having 20 type A hardness provided by JIS K6253, with a curable silicone resin providing a cured product having 30 type D hardness provided by JIS K6253, and curing the silicone resin to provide a cured resin layer having 0.5 mm thickness.
