High anticorrosive performance electrophoretic paint for
engineering machinery
Product Introduction :
HLS-1701BLB/HLS-1701B 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 :
The bath has strong anti-shrinkage and anti-pollution ability.
Strong anti-corrosion properties, good salt spray resistance
workpiece edge.
Ideal for high demand for salt spray industry, such as pipe trench,
auto chassis parts, castings
Coating fullness of good, better substrate hiding .

Construction equipment :
Cathodic electrophoretic coating construction in the
electrophoresis tank, so need to have the following equipment:
Electrophoresis tank
Circulation devices (including filter, fill the paint device)
DI water equipment
DC power supply and the power supply unit
Anode box (tube) and circulation device
Ultrafiltration device
Cleaning devices
Heat exchanging equipment
Curing device
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.
