Black matte epoxy electrophoretic paint for 3C electronics parts
Product Introduction
HL-1607LB/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:
coldandhotrolledsteelsheet,galvanizedsteel sheetandstainless
steelsheetetc
This product features shown below:
| Good stability of bath can adaptable for a longer updating cycle |
| High throwing power, internal and external uniformity. |
| Excellent leveling coating, good bonding for ceand compatibility
with plastic powder |
Main ingredients:
Pigment: carbon black, kaolin, antirust pigment
Solvent: alcohol ether
Additives: surface active agent, prevent shrinkage cavity agent
