Car chassis black electrophoretic paint like Frame bridge plate spring
Product Introduction
HLS-1701ELB/HLS-1701EG Black 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:
The bath has strong anti-shrinkage and anti-pollution ability.
Strong anti-corrosion properties, good salt spray resistance workpiece edge.
etc.
The main component Matrix resin:
Neutralizing agent: organic acid
Solvent: alcohol ether
