RESIN-COATED METAL SHEET HAVING AN EXCELLENT FILM PEELING RESISTANCE DURING ROLL FORMING

摘要

ABSTRACT OF THE DISCLOSURE A resin-coated metal sheet comprising a resin film made from a surface treating composition, characterized in that Sward rocker hardness of the resin film has 35 or more and the depth of penetration of an indenter in a nanoscratch test is less than 0.3 pm. The resin-coated metal sheet according to the present invention has desirable properties of the resin-coated metal sheet such as corrosion resistance and is less likely to cause trouble to the roll forming operation.
