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
