Health and safety

This powder coating is a non-toxic product, but should avoid inhaling dust during use. It is recommended that operators wear appropriate dust masks and eyes. If possible, avoid long-term direct contact between skin and powder coatings.

Storage requirements

Store in a 28° C Celsius, ventilated, dry, clean room in hell. Keep away from fire, heating, and direct sunlight. Do not stack in the open air. Under these conditions, the powder can be stored stably for 12 months. If it exceeds the storage period, it can be re-inspected. If the test results meet the requirements, they can still be used.
