Solution for Compressor electrodeposition coating
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:
Ultra low temperature curing completely green does not contain heavy metals, in conformity with the European ROHS, the instruction of PAHs, reach, fohs, can save about 60% of the energy consumption, is the national government absolute attention and support energy-saving emission reduction requirements of the project, the state and the enterprises and the people.
Main ingredients:
Additives: surface active agent, prevent shrinkage cavity agent
Pigment: carbon black, kaolin, antirust pigment
Neutralizing agent: organic acid
Matrix resin: Acrylic modified epoxy resin
