Quick Information

  • Brand Name: HAOLISEN
  • Place of Origin: China
  • Model Number : HL-1607LB/HLS-1701A

Description

Passenger cars and commercial vehicles seat Black electrophoresis paint

 

Product Introduction:

 

 HL-1607LB/HLS-1701A 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 and stainless steel sheet etc.

 

This product features shown below:

 

The appearance of the coating is flat, delicate, smooth, uniform high gloss.

 

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

 

The bath has strong anti-shrinkage and anti-pollution ability.

 

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

Coating fullness of good, better substrate hiding .

 

 

The main component Matrix resin:

 

polyurethane modified epoxy resin

 

Curing agent: totally enclosed multi-isocyanates

 

Neutralizing agent: organic acid

 

Solvent: alcohol ether

 

Additives: surface active agent, prevent shrinkage cavity agent

 

Pigment: Titanium pigment, carbon black, kaolin, antirust pigment
