Low temperature curing colorful electrophoresis paint
Product Introduction :
OHT-825 Ultra Low temperature color 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
This product features shown below :
Good stability of bath can adaptable for a longer updating cycle.
| High penetration and good uniformity of internal and external |
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.

Bath on site management project :
Good bath data and coating quality, from the strict parameters
management and maintenance of equipment, production line according
to its own reality time situation, can have different management
project and specifications, recommend the construction parameters
