The above tests all use 0.8mm pure aluminum plates, and the coating thickness is 60～80um. The performance indicators of the coating will vary slightly with the gloss.
This product does not contain heavy metals such as arsenic, selenium, lead, hexavalent chromium, mercury, antimony, cadmium, etc., and complies with RoHS requirements.
Storage conditions: Store in a dry, ventilated room at around 25°C, away from direct sunlight. Under this condition, the powder can be stored for 12 months. If it exceeds the expiration date, it can be re-tested and can still be used if the results meet the requirements.
Note: The test indicators mentioned in this report are all data obtained from laboratory tests and are for reference only, not as a performance commitment for product application. The results may vary depending on environmental factors and other conditions.
