TRANSPARENT FLUOROPLASTIC COATED STAINLESS STEEL PANEL EXCELLENT IN ABRASION RESISTANCE AND SCRATCH RESISTANCE

摘要

PROBLEM TO BE SOLVED: To enhance abrasion resistance and scratch resistance in a coated stainless steel panel wherein a transparent fluoroplastic coating film containing a polytetrafluoroethylene powder is formed on the chromate film with a total Cr content of 5-40 mg/m2 formed on the surface of a stainless steel panel. SOLUTION: A transparent fluoroplastic coating film comprises an acrylic resin-compounded polyvinylidene fluoride resin and contains 1-20 wt.% of a polytetrafluoroethylene powder with a particle size of 3-40μm and wax is added to this coating film. As wax, paraffin wax and microcrystalline wax is pref. The thickness of the transparent fluoroplastic coating film is pref. set to 10-30μm.
