All Color Texture Wrinkle Sand Crocodile Olyester Powder Coating for Metal

When customers use our powder coating, due to the poor sanitation and cleanness of key parts such as powder spraying room, spray gun, fluidizing barrel, etc., the new powder is interfered in the use process, resulting in the phenomenon of light loss. Powder coating in the oven over the specified time and temperature, there will be surface loss of light. Between each batch and batch, when the new powder and the recycled powder are mixed, the surface loss of light is easy to occur. The storage tim

In the process of using matte powder coating, when it is mixed with other planes, the gloss of the coating will be increased easily due to the high gloss powder. If the curing temperature of the powder coating is too low or the time is not enough, the gloss of the coating will change. In case of any of the above problems, it is recommended that the customer do a good job of cleaning before production. If it is the reason of baking temperature, it is recommended that the customer test the furnace

There is residual pretreatment liquid on the surface of the coating If the baking time is too long, or the baking temperature is too high, the coating will turn yellow, especially the indoor powder coating. Other powder coatings are mixed in the spraying process The pigment of powder coating itself is not resistant to high temperature or the resin is prone to yellowing. For the above problems, we can The customer improves the pre-treatment process and completes the pre-treatment. Strictly follow

The pre-treatment of the workpiece is not in place, and there is oil residue. The compressed air contains oil, water, etc., resulting in powder pollution. Contaminated by dust or other impurities. The powder coating itself is polluted. For the above problems, we can Strengthen the pretreatment process control. Check the air tank and air compressor regularly, and discharge the oil and water in the air tank in time. Thoroughly clean the site environment and keep the drying channel clean.

There are pores on the surface of the coated workpiece The workpiece surface is not degreased and derusted thoroughly The conductive putty is too thick to dry completely The spray gun is too close to the workpiece, and the spraying voltage is too high, resulting in coating breakdown There is volatile gas in the drying channel The coating is too thick or the coating is not fully cured For the above problems, we can Strengthen the surface treatment of workpieces Improve the pretreatment process Ex
