COATING COMPOSITION FOR SURFACE TREATMENT OF ELASTIC POLYMER MATERIAL

摘要

PURPOSE: To obtain a surface treatment coating compsn. suitable for surface treatment of a weatherstrip with an improvement in the durability of a coating compsn. for surface treatment of an elastic polymer material and with low noises being hardly generated during friction. CONSTITUTION: The coating compsn. for surface treatment of an elastic polymer material comprises 100 pts.wt. curable polyurethane and 0.5-100 pts.wt. diorganopolysiloxane having an average degree of polymn. of 6,000 to 10,000. This compsn. is pref. formed into a predetermined shape and used as a weatherstrip.
