Cautions

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

2. The storage stability of powder coatings formulated with VTL-508 is good, but still need to avoid high-temperature environment.

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