High weatherability Black electrophoretic paint with Uv radiation
resiistance
Product Introduction :
HR-4000BLB/HR-6000 the bottom of one black cathode electrophoretic
coating, 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:
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 |
