Solution for the washing machine electrophoresis paint
Product Introduction :
HS-6060LB/HS-2568G Gray Cationic Epoxy Electrocoat for auto is a new generation electrophoretic coating researched and developed by HLS Paint (Shanghai) Co., Ltd.
It represents modern technology of cathodic electrophoretic coating that is environment-friendly with high property and low cost. Such coating does not contain heavy metal like lead, tin, cadmium and mercury etc. It is a two-component, water-dispersed resin,meanwhile, it took in features of previous products, and can adapt galvanized steel sheet perfectly, almost can be applied to foundation coating of all metal,
such as: cold and hot rolled steel sheet, galvanized steel sheet, aluminum products, zinc-aluminum alloy sheet and stainless steel sheet etc.
