Notes:
1. Powder coatings have a high standard for the working environment. The environment should have excellent ventilation and a temperature of less than 35°C.
2. The smooth finish powder coating should be stored in a cool, dry place, avoiding powder caking or solidification while spraying.
3. Our coating is 100% solid powder. Workers must take protective measures and wear protective clothing and avoid skin contact with the powder coating. If the skin does come into contact, was immediately with soap and water.
4. After the spraying process, the powder will be exposed to static electricity and create a coating layer on the workpiece in order to achieve the desired effect. The spraying device should be grounded, eliminating the static electricity from touching the device. By doing so, users ensure the entire coating and spraying process won’t be affected by static electricity.
