• The above tests all use 0.8mm degreased and derusted cold-rolled steel plates, with a coating thickness of 60~80um. The performance indicators of the coating will vary slightly with different gloss.

Environmental requirements: This product does not contain heavy metals such as tin, selenium, lead, hexavalent tantalum, mercury, zinc, cadmium, etc., and fully complies with RoHS 2.0 environmental protection requirements.

Note: We will provide complete powder coating consultation and customized application solutions according to the actual needs of each customer. The test indicators mentioned in this report are the data obtained by laboratory testing and are for reference only, not as performance commitments for product applications. The results will vary with environmental factors and electrical stacking.
