Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an aluminum coating material which attains extremely excellent moldability effectively by preventing generation of cracks, wrinkles, peeling off and the like of a hardened film formed on a surface in molding mainly including pressing work such as draw forming and bending work, and which displays excellent water repellent properties even after such molding. SOLUTION: The water repellent aluminum coating material of excellent moldability is constituted by applying a composition to a surface of an aluminum material and hardening it. The composition includes a specific organopolysiloxane having a silanol group at a rate of 3 to 70 pts.wt. to a specific organopolysiloxane of 100 pts.wt. |
