Summary: | PURPOSE:To prevent the blocking of a halogen-containing rubber molded article to the contacting object by coating the article with a reactive silicone liquid composed of a specific composition and drying the applied liquid. CONSTITUTION:A molded article of a halogen-containing rubber (e.g. chloroprene rubber or epichlorohydrin rubber) is coated with a reactive silicone liquid composed of (A) 100 pts.wt. of an organic polysiloxane, (B) 80-120 pts.wt. of a silane coupling agent and (C) 5-15 pts.wt. of an organic metal salt and the coating layer is dried by heating at 80-120 deg.C for 5-20min to form a coating film having an average thickness of 1-20mum, preferably 5-10mum. |
