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. 

Ideal for high demand for salt spray industry, such as pipe trench, auto chassis parts, castings

The main component Matrix resin:

Neutralizing agent: organic acid

Solvent: alcohol ether

Matrix resin: polyurethane modified epoxy resin
