cathodic epoxy electrocoat
Solution for radiator electrodeposition coating
Product Introduction :
HS-5500LB/HS-5500 White epoxy acrylic cathodic electrophoretic coating for auto is the 8th generation electrophoretic coating researched and developed by HLS Paint (Shanghai) Co., Ltd. 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.
This product features shown below:
High throwing power, good internal and external uniformity.
Simple control of bath and wide operation range is suitable for the operation specification and site equipment for different customers.
Low curing temperature, coating yellow degeneration resistance is good, suitable for electrodeposition primer, and then to spray or paint coating process, such as: oil heater, radiator, heater, lamps and lanterns, machinery, home appliances and hardware products and other industries.
|Pigment: titanium dioxide, kaolin,antirust pigment|
|Neutralizing agent: organic acid|
|Additives: surface active agent, prevent shrinkage cavity agent,resistance to yellowing 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:
