How to avoid color difference in powder coating

Powder coating, we should know what it is used to do, mainly used to spray it on the object, because the powder coating processing technology and materials are different, so its role is not the same, but in the spraying are similar, but we want to spray powder coating on the object, we often encounter the problem of color difference, now In the iron and steel electrostatic powder coating, this paper introduces the causes and solutions of color difference problems in powder coating spraying.

There are three reasons for this situation, one is that the furnace temperature is too high or too low, the second is that the curing time is too long or too short, and the third is that the exhaust gas of the curing furnace is insufficient. All of these three situations will cause color difference when we spray powder coatings on objects.

The solutions are as follows: 1. For the first case, we need to adjust the furnace temperature to a suitable temperature. 2. For the second case, we need to adjust the chain speed. 3. For the third case, we need to check the exhaust system or increase the exhaust vent. Hope to help you in the case of color difference in powder coating spraying.
