Solution for electrophoresis paint for grader
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.
1,Strong anti-corrosion properties, good salt spray resistance workpiece edge.
2,Good stability of bath can adaptable for a longer updating cycle.
3,Excellent leveling coating,good bonding force and compatibility with plastic powder
|
Matrix resin: polyurethane modified epoxy resin
|
Curing agent: totally enclosed multi-isocyanates |
|
Neutralizing agent: organic acid
|
Additives: surface active agent, prevent shrinkage cavity agent |
Bath on site management project :
Good bath data and coating quality, from the strict parameters management and maintenance of equipment, production line according to its own reality time situation, can have different management project and specifications, recommend the construction parameters see the table below for reference:
