① The air has high relative humidity and high temperature, and the solvent evaporates quickly.
②Water in the solvent or diluent.
③The coating surface is contaminated by moisture.
④ The air compressor is malfunctioning, and moisture is brought into the paint.
⑤The dissolving power of the thinner is not enough, which makes the resin of the paint precipitate and turn white.
⑥ Hand sweat contaminates the workpiece.
⑦The moisture content of the base material is relatively high.
① Adjust the temperature of the construction environment and reduce the relative humidity.
② Pay attention to choosing better quality paint.
③Strengthen the temperature control of the coating room.
④Repair the oil-water separator to prevent moisture from entering the coating.
⑤Choose a suitable diluent.
