Electrophoretic coating for automobile skylight industry
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:
Coating fullness of good, better substrate hiding .
Ideal for high demand for salt spray industry, such as pipe trench, auto chassis parts, castings etc.
Neutralizing agent: organic acid
The main component Matrix resin:
| Additives:surface active agent, prevent shrinkage cavity agent |
| Pigment:Titanium pigment, carbon black, kaolin, antirust pigment |
| Matrix resin:polyurethane modified epoxy resin |
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:
