Solution for application of electrophoresis paint of fertilizer machine
Product Introduction :
HLS-1701BLB/HLS-1701B Black 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 and stainless steel sheet etc.
This product features shown below :
1, Good stability of bath can adaptable for a longer updating cycle.
2, Coating fullness of good, better substrate hiding .
3, Strong anti-corrosion properties, good salt spray resistance workpiece edge.
