Product Introduction
HL-1605LB/HL-1530G 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 coatingthat isenvironment-friendly withhigh propertyandlow cost. Such coatingdoesnot 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, andcan adapt galvanized steel sheet perfectly,almost canbe applied to foundation coating of all metal
suchas: cold and hot rolled steel sheet, galvanized steel sheet, aluminum products, zinc-aluminum alloy sheet and stainless steel sheetetc
This product features shown below :
|
The appearance of the coating is flat,delicate,smooth.
|
|
The bath has strong anti-shrink age and anti-pollution ability
|
|
Coating fullness of good,better substrate hiding.
|
The main component Matrix resin :
|
Neutralizing agent: organic acid
|
Solvent: alcohol ether |
|
Pigment: carbon black, kaolin, antirust pigment
|
Curing agent: Fully enclosed multi isocyanate |
