Engineering mechanical grey electrophoretic paint
Product Introduction:
HS-6060LB/HS-2516G Gray 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. | Good stability of bath can adaptable for a longer updating cycle. |
| Coating fullness of good, better substrate hiding . | Excellent leveling coating,good bonding force and compatibility
with plastic powder. |
The main component Matrix resin:
Matrix resin:polyurethane modified epoxy resin
Curing agent:totally enclosed multi-isocyanates
Additives: surface active agent, prevent shrinkage cavity agent

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.
