Typical Quality Tests for Evaluating Powder Coating
创建于2024.07.02
Several tests are commonly used to evaluate the quality of powder coatings:
- Salt Spray Test (ASTM B117): Tests the coating's corrosion resistance in a high-salt environment.
- Impact Test (ASTM D2794): Evaluates the coating's resistance to physical impacts.
- Chemical Resistance Test (ASTM D1308): Assesses the coating's resistance to chemical solvents.
- Adhesion Test (ASTM D3359): Measures the coating's adhesion strength.
- Hardness Test (ASTM D3363): Uses pencils to measure the coating's hardness.
- Flexibility Test (ASTM D522): Assesses the coating's performance when bent.
- Gloss Test (ASTM D523): Measures the surface gloss of the coating.
These tests comprehensively evaluate the performance of powder coatings, ensuring they meet quality standards.
