Epoxy powder coating is made from epoxy resin with different properties and Chelsea curing agent. It is characterized by energy saving, low pollution and high efficiency. Not only can be a film, coating efficiency is high, and the surface coating anti-corrosion performance is good, high mechanical strength.
The powder coating is mainly used in construction, decoration, household appliances, metal furniture, instruments, highway guardrail, auto parts, fitness sports equipment coating and other industries.
Polyester resin powder coating is made of carboxyl polyester resin, pigment filler and TGL as curing agent, with super weather resistance and UV resistance. Good mechanical properties, high hardness, scratch resistance, corrosion resistance; Good leveling property, the film is basically free of pinholes, shrinkage holes and other defects; It can be used for outdoor metal products such as air conditioner, outdoor lamps and lanterns.
Notes:
1.The above tests used 0.8mm thick cold-rolled steel plates with a coating thickness of 60-80 microns.
2.The performance index of the above coating may change with the change of color and gloss.
Average coverage:
8-11 sq.m./kg; film thickness 70 microns (calculated with 100% powder coating utilization rate
