The quality inspection of paint can generally be divided into: performance inspection of the paint itself, such as transparency, color, specific gravity, non-volatile matter, fineness, viscosity, rheology, skinning, storage stability, etc. Performance inspection during operation, such as leveling, sanding, hiding power, usage amount, drying time, etc.; paint film quality inspection after film formation. Such as: paint film thickness, gloss, color, hardness, impact strength, flexibility, adhesion, abrasion resistance, scrub resistance, yellowing resistance, etc.
In addition to general quality checks, some specialized performance tests are also required. Such as atmospheric exposure and artificial accelerated aging test for weather resistance, three-proof performance test for tropical paint, chemical resistance test for anti-corrosion paint, etc.
