Use 600#~800# to polish the surface of plastic parts, clean them with clear water, dry them, and then wipe them with degreasing agent. Plastic primer does not need to be mixed with other auxiliary materials, and can be directly sprayed and covered by fog spray twice. Pay attention to spraying, not too thick, which will affect the adhesion between top coat and substrate, with an interval of 3~5 minutes.

Precautions:

1, plastic products are insulators, and the surface resistance is generally around1013Ω, which is easy to generate static electricity. When charging, it is easy to absorb fine dust in the air and attach to the surface. Because it is difficult to remove electrostatically adsorbed dust by general blowing method, it is best to use high-pressure ionized airflow to remove electrostatic precipitation at the same time.

2. Spraying: The thickness of plastic coating is 15~20μm, and it usually needs 2~3 layers. Dry for15min after the first spraying, and then spray for the second time. Surfaces that need to be bright must also be sprayed with transparent paint. The coated parts have little effect on flame retardancy.

3. Drying: After coating, it can be dried at room temperature or baked at 60℃ for 30 minutes.
