Abstract
A method of reducing surface tackiness of a silicone rubber cured product is provided. The method includes coating the surface of a cured product of a curable silicone rubber composition, which has a molar ratio within the composition of hydrogen atoms bonded to silicon atoms relative to alkenyl groups bonded to silicon atoms of 1.0 or greater, and which, following curing, exhibits a type A hardness prescribed in JIS K6253 of no more than 20, with a curable silicone resin layer which, following curing, exhibits a type D hardness prescribed in JIS K6253 of 30 or greater; and subsequently curing the silicone resin to form a cured resin layer with a thickness of no more than 0.5 mm. Adhesion of dirt to the surface can be prevented.
