Environmental Compliance
The supplied product information states that the coating does not contain certain listed restricted substances, including arsenic, selenium, lead, hexavalent chromium, mercury, antimony, and cadmium, and reports compliance with RoHS requirements. Please confirm the applicable product declaration or test report before making a formal compliance claim.
Storage Conditions
Store in a dry, well-ventilated room at approximately 25°C, away from direct sunlight and heat sources. Under the stated conditions, the recommended storage period is 12 months. If the product exceeds its storage period, it may be retested and used only if the results meet the applicable requirements.
Disclaimer
The test values are laboratory results provided for reference and do not constitute a performance guarantee for every application. Actual coating performance may vary depending on substrate preparation, pretreatment, film thickness, curing conditions, gloss level, and environmental factors.
