Electrophoretic coating for locomotive industry
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:
| The appearance of the coating is flat, delicate, smooth. |
| Good stability of bath can adaptable for a longer updating cycle. |
| Have excellent corrosion resistance and weathering resistance, especially suitable for the bottom surface of a painting |
Main ingredients
| Matrix resin: | Acrylic modified epoxy resin |
| Curing agent | Fully enclosed multi isocyanate |
| Additives | surface active agent, prevent shrinkage cavity agent |
