COMPOSITION FOR COATING FILM FORMATION PURPOSES

摘要

The surface of a base is treated with a composition for coating film formation purposes, wherein the composition comprises (A) a silicone resin containing an alkenyl group, (B) a silicon-atom-bound and hydrogen-atom-containing organopolysiloxane containing 10-160 siloxane units on average, and (C) a condensation reaction catalyst. The composition enables the formation of a water-repellent coating film that exhibits high hydrophobicity after being washed with a solvent and has sufficient water-skiing performance, and also enables the provision of a base, e.g., a heat-releasing plate, having high hydrophobicity.
