Special refrigerator white electrophoresis paint
Product Introduction :
HS-5300LB/HS-5300 White epoxy acrylic cathodic electrophoretic coating 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,and get the national invention patent and the Shanghai science and technology commission of high-tech transformation project.
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. The coating that does not contain tin element meet the latest environ-mental regulations of European Union, North America, Japan and other requirements in advance, which is the inevitable trend of future environ-mental coating and low cost; 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.
Main ingredients:
Additives:surface active agent, prevent shrinkage cavity agent
Curing agent: totally enclosed multi-isocyanates
Pigment: carbon black, kaolin, antirust pigment
This product features shown below:
