Product Introduction
HLS-1701ELB/HLS-1701EG 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, zinc-aluminum
alloy sheet and stainless steel sheet etc.
This product features shown below:
The bath has strong anti-shrinkage and anti-pollution ability.
|
Strong anti-corrosion properties, good salt spray resistance
workpiece edge. |
The main component Matrix resin:
Neutralizing agent: organic acid
Solvent: alcohol ether
Matrix resin: polyurethane modified epoxy resin

Storage, packaging and transportation
This product is a water-borne industrial coatings, non-hazardous,
non-inflammable and explosive products; transportation to prevent
direct sunlight, avoid freezing (>5℃ ); Packaging for 50/60/200L
Plastic barrel; in the transport and storage of drums should be
maintained clean, avoid charging the dirt brought in on drums
during filling tank, again checked and confirmed that the quality
of products, including paste resin, emulsions and additives should
be indoor storage, good ventilation, dry, protect against freezing
and overheating, the storage temperature should be controlled at
5～35℃, products from the date of production, over shelf,
experimentation is required to determine whether can continue to
use.
