Black High throwing power (Four-box method) penetration electrophoresis paint
Product Introduction :
|
HR-7001LB/HR-7010 Gray Cationic Epoxy Electrocoat for auto is the 8th generation electrophoretic coating researched and developed by HLS Paint (Shanghai) Co., Ltd. in cooperation with Germany HS International Chemical Industry Group.
|
|
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:
|
The appearance of the coating is flat, delicate, smooth. | Good stability of bath can adaptable for a longer updating cycle. |
|
Strong anti-corrosion properties, good salt spray resistance workpiece edge. | Coating fullness of good, better substrate hiding . |
|
suitable for auto body industry, such as cars, SUV and other models
