Cautions

1. Tested polyester resins with low film gloss under 160°C/20min curing condition: Guanghua GH-1156, Yongli YL-5075, Yochon YC-5012B, Shenjian SJ-3B.

2. Tested polyester resins with low film gloss under 170°C/15min curing condition: Sino-French P5072, Xiangrong XR-5022X, Zhengjie ZJ-5054, Shenjian SJ-3B, Yinyang YE-5050, Tiansong TS-5700.

3. It is recommended to conduct a small sample test before mass production.

4. The storage stability of powder coatings formulated with VEL-409 is good, but still need to avoid high-temperature environment.

5. The above formulations are for reference only. Since the properties are different due to different resin manufacturers, please refer to the test data.
