Solution for the freezer 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:
1,The appearance of the coating is flat, delicate, smooth, uniform high gloss.
2,Excellent leveling coating,good bonding for ceand compatibility with plastic powder.
The main component Matrix resin:
①,Neutralizing agent: organic acid
②,Solvent: alcohol ether
③,Pigment: carbon black, kaolin, antirust pigment
④,Curing agent: Fully enclosed multi isocyanate
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:
