1: Aluminum pigment metallic effect: level 1-6 (level 6 is the highest)

2:Aluminum pigment whiteness, brightness, and different colors at different angles are commonly used to qualitatively describe the reflection effect of lead paint coating on light at different angles and the changing trend of the effect. The corresponding quantitative measurement can be obtained by measuring the intensity of reflected light at different angles.

3: Aluminum pigment surface smoothness: A description of the particle size and dispersion uniformity of aluminum pigments in the coating.

4: Aluminum pigment hiding power: The metallic opacity of aluminum pigments varies with the difference in particle size and shape of aluminum pigments. 5: Adhesion: the affinity of aluminum pigments and coating systems. It is related to the resins, solvents, and additives of the coating system, as well as the shape of the aluminum pigment particles, the surface and coating conditions, and the residual additives on the surface. The "silver drop" phenomenon is a manifestation of poor adhesion.

6: Aluminum pigment electrical insulation, chemical resistance, and weather resistance: Aluminum is an active amphoteric metal. After surface treatment, aluminum pigments can exhibit high-voltage insulation, inertness to acid and alkali environments, and resistance to air, humidity, and humidity. Inertness to temperature changes.
