High Performance Electrophoresis Paint , Electrocoating Anti Rust Coating For Car Wipers

Solution for the Car wipers electrophoresis paint.

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: 



1.Good stability of bath can adaptable for a longer updating cycle. 

2.Strong anti-corrosion properties, good salt spray resistance workpiece edge. 

The main component Matrix resin:

Solvent: alcohol ether	Additives: surface active agent, prevent shrinkage cavity agent
Pigment: Titanium pigment, carbon black, kaolin, antirust pigment
