Powder Coating Gloss

Powder coating gloss refers to the ability of the coating surface to reflect light, measured by a gloss meter as the reflectance of light at a specific angle of incidence. The principle is based on the specular reflection of light on smooth surfaces, while rough surfaces cause scattering. Its role lies in evaluating the uniformity of the coating's appearance and is applied in quality control to assess the stability of spraying processes, such as checking surface consistency in household appliances and building materials.
Selection
Consider the measurement angle when selecting: use a 20° angle for high gloss, 60° for medium gloss, and 85° for low gloss. Determine the gloss range based on product standards, and compare the numerical deviation between the sample and the standard plate. The environment should avoid strong light, and the instrument must be regularly calibrated using a standard plate. For dark-colored samples, multi-angle measurement is preferred.

Sand Falling Test Apparatus for Measuring the Wear Resistance of Powder Coatings
The sand falling test instrument determines the wear resistance of powder coatings by simulating sand particle impact. During the test, abrasive material falls vertically from a specified height, continuously scouring the coating until the substrate is exposed. The wear resistance is evaluated based on the mass of abrasive material consumed.

Pendulum hardness tester measures the damping hardness of powder coatings.
This article introduces the method of testing the damping hardness of powder coatings using a pendulum hardness tester. The test is based on the principle of energy attenuation, where the hardness is reflected by the time it takes for the amplitude of the pendulum to decay as it swings on the coating surface, with a longer time indicating a harder coating.
Haze meter detects haze on high-gloss coating surfaces
Haze is the phenomenon where a high-gloss coating surface causes a blurring of reflected images due to light scattering, which reduces visual clarity. A haze meter quantifies the haze value by measuring the intensity ratio between the specularly reflected light and the scattered light at specific small angles. The lower the value, the clearer the surface.
