Electrophoretic coating for domestic microwave oven
Product Introduction :
HS-6060ALB/HS-6600 White 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.
This product features shown below:
Excellent leveling coating,good bonding force and compatibility with plastic powder.
Strong anti-corrosion properties, good salt spray resistance workpiece edge.
Good stability of bath can adaptable for a longer updating cycl
Main ingredients:
| Pigment: titanium dioxide, kaolin,antirust pigment | Neutralizing agent: organic acid |
