High weatherability colorful electrophoretic paint with Uv
radiation resiistance
Product Introduction :
HR-4000BLB Epoxy acrylic Color Cationic Electrocoat is HLS Paint
(Shanghai) Co., Ltd., the eighth generation of independent research
and development of electrophoretic coating. This coating by epoxy
acrylate modified, the film also has excellent corrosion resistance
and weatherability, smooth appearance and full, suitable as a base
topcoat system. In addition, the lead, cadmium, chromium, mercury
and other heavy metals, two-component, water dispersible resin, at
the same time, previous generations of the product characteristics,
have good adaptability to the galvanized steel, almost can be
applied to all metal coating, such as: cold hot rolled steel,
galvanized steel, aluminum, zinc Aluminum Alloy plate, stainless
steel plate.
This product features shown below :
The appearance of the coating is flat, delicate, smooth.
Good stability of bath can adaptable for a longer updating cycle.
The bath has strong anti-shrinkage and anti-pollution ability.
High penetration and good uniformity of internal and external.
Have excellent corrosion resistance and weathering resistance,
especially suitable for the bottom surface of a painting system.
