Super-liquid-repellent coating film and curable composition for forming super-liquid-repellent coating film

Abstract

The present invention addresses the problem of providing a super-liquid-repellent coating film that has improved abrasion resistance. Provided as a means for solving the problem is a coating film that has a fluorine atom content of 1 to 60 wt %, the coating film having a surface that has an average surface roughness Ra of 0.5 to 20, a surface area ratio of 1.7 to 5, a contact angle with water of 150° or more, a contact angle with n-hexadecane of 80° or more, and a surface that has a contact angle with water of 150° or more after being rubbed 100 times with a PET film under a load of 100 g.
