Test performance and test method of gloss finish
Test performance and test method of gloss finish
Cover finish paint is a kind of decorative paint, which is characterized by the formation of a smooth, uniform, shiny surface coating. Cover finish paint is widely used in automobile, furniture, construction and other fields to improve the decorative effect and appearance quality of products. Gloss finishes are available in different glossiness, color, coating quality and durability according to different requirements and application scenarios.
Performance of detection
The following is a brief description of the performance parameters to be tested for the cover finish, as shown in the following table:
| Parameters of performance | Method of test |
|---|---|
| Degree of gloss | Glossometer measurement |
| Difference of color | Color comparator measurement |
| Hardness of hardness | Pencil hardness measurement |
| Degree of viscosity | Viscometer measurement |
| Drying time | Oven method measurement |
| Resistance to weather | Artificial accelerated aging test |
| Resistance to chemicals | Chemical resistance test |
| Resistance to abrasion | Wear out test |
| Force of adhesion | Cross grid method of measurement |

Method of detection
The following is a detailed description of the test method for the performance parameters to be tested:
Gloss: Use a gloss meter to measure the gloss of the cover finish to evaluate the gloss effect and gloss stability of the surface.
Color difference: Use a color comparator to measure the color difference of the mask finish to evaluate its color consistency and accuracy.
Hardness: Using the pencil hardness measurement method, a scratch test with a pencil is performed to evaluate the hardness and wear resistance of the finish.
Viscosity: The viscosity of the finish is measured using a viscometer to assess the brushing performance and quality of the coating.
Drying time: The drying time of the cover finish was measured using the oven method to evaluate its construction efficiency and coating quality.
Weather resistance: The weather resistance of the finish was evaluated using an artificial accelerated aging test to evaluate its oxidation resistance, UV resistance and other properties under different climatic conditions.
Test performance and test method of gloss finish
Chemical resistance: Chemical resistance tests are used to evaluate the chemical resistance of the finish to assess its resistance to exposure to chemicals.
Wear resistance: Wear tests are used to evaluate the wear resistance of the finish to assess its resistance to wear.
Adhesion: The adhesion of the finish was measured using the cross scratch method to assess the firmness of the coating.
We remind you: different performance parameters may require different test methods and equipment, and there may be some industry standards and specifications, for the performance test of cover finish paint, you should also select the corresponding test methods and standards according to the actual needs.
