Product name: Low temperature curing powder coating
General introduction:
This product is made of special formula and production process for medium density fiberboard substrate (MDF) coating powder coating, the coating has excellent mechanical properties and performance of indoor decoration, can be widely used in coating industry. Modern furniture is generally not recommended directly used for surface coating of various outdoor supplies.
Product Series:
Can be made into a variety of colors and with a metallic flash effect of sand or hammer coating.
Physical properties:
proportion(g/cm3, 25℃):1.2-1.8
Distribution of particle size: 100% less than 100 microns(can be adjusted according to special requirements of coating)
Construction process:
Can be used for electrostatic spray gun coating, film thickness is suitable for control in the 70-90um. (MDF substrate in advance with an infrared oven to heat up the preheating treatment, the specific heating temperature according to MDF substrate heat capacity to determine the size.)
Curing conditions:
120 ℃ (refers to the MDF plate surface temperature), 20 minutes. Oven can be used ordinary hot air circulation oven or bake Road, the conditions allowed to use the first infrared oven on the spray just a good coating of the rapid heating leveling, and then into the ordinary oven bake curing.
Coating performance:

Salt spray test | GB 1771-1991 | >500 hours |
Hot and humid test | GB 1740-1989 | >1000 hours |
Note | 1. The above test uses 0.8 mm thick cold-rolled steel sheet with standard treatment, and the coating thickness is 60-80 um. | |
2. The performance of the above coating may change with gloss and art effects. |
Average coverage:
About 8-9 m2/kg, The film thickness is about 70um (calculated with 100% powder coating usage)
