Electrophoretic coating for hardware tool industry
Product Introduction
HL-1607LB/HL-1500G 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,
This product features shown below:
The appearance of the coating is flat, delicate, smooth, uniform high gloss. |
Stronganti-corrosionproperties,goodsaltsprayresistanceworkpieceedge. |
Coatingfullness ofgood,bettersubstratehiding |
Excellent leveling coating,good bonding for ceand compatibility with plastic powder. |
.
The main component Matrix resin:
Neutralizing agent: organic acid
Solvent: alcohol ether
Pigment: carbon black, kaolin, antirust pigment
Curing agent: Fully enclosed multi isocyanate
