Performance Testing: Appearance Color Gravity Viscosity Fine Degree Acid Value Solid Content Hiding Power Usage Consumption Drying Time Lacquer Grindability Flow Characteristics Adhesion Film hardness Flexibility Impact strength Wear resistance Viscoelasticity Glossiness.

1, aging test: salt fog aging, high and low temperature cycle, photo-aging, ozone aging, artificial aging and other aging items.

2. Physical Properties: Container Appearance, Appearance, Transparency, Whiteness, Color, Adhesion, Viscosity, Fineness, Ash, PH, Flash Point, Density, Hardness, Volume Solids, Nonvolatile Content, Storage Stability , Contrast ratio, outflow time, back to sticky and so on.

3, chemical properties: weatherability, abrasion resistance, acid and alkali resistance, gasoline resistance, impact resistance, bleed, water resistance, heat and humidity resistance, volatile oil resistance, stain resistance, salt spray resistance, Layer temperature resistance, stain resistance, washability, boiling resistance, detergent resistance, solvent wiping and so on.

4, the construction performance: hiding power, consumption, consumption, drying time (table dry, hard work), paint the grinding, leveling, sagging, the thickness of the film (wet film thickness, dry film thickness), paint Film heating test, cross-hatch test.

5, harmful substances: VOC, benzene content, toluene, ethylbenzene, total xylene, free formaldehyde, total TDI and HDI content, glycol ethers, heavy metal content (lead, mercury, chromium, cadmium).

6, electrical properties of paint: electrical conductivity, breakdown voltage or breakdown strength, insulation resistance, dielectric constant, dielectric loss.
