Low temperature curing Black electrophoresis paint for shock absorber and Compressor
Product Introduction :
OHT-825/OHT-825 Ultra Low temperature Black Cationic Epoxy Electrocoat, is HLS Paint (Shanghai) Co., Ltd. the ninth generation of independent research and development of electrophoretic coating. The lead, cadmium, chromium, mercury and other heavy metals, two-component aqueous dispersion resin. At the same time, inherited the characteristics of several generations of product quality, OHT-825 on galvanized steel sheet has good adaptability, almost at the bottom of all the metal material coating, such as: cold rolled steel, galvanized steel, aluminum, stainless steel plate, rubber parts, zinc and aluminum alloy plate, such as applicable.
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. |
| The ability of corrosion resistance is strong, and the edge of the workpiece is good in salt spray resistance |
Main ingredients:
| Curing agent: Modified low temperature curing agent |
| Matrix resin: Acrylic modified epoxy resin |
| Solvent: alcohol ether |
| Pigment: carbon black, kaolin, antirust pigment |
