Package and transport

20KG/carton,the cartons lined with polyethylene plastic bag, not dangerous goods, can use different way to transport, should avoid direct sunlight, avoid sweating and heating, avoid contact with chemicals

Storage requirements

• Store under 30°C, wet, clean indoor, can’t be close to fire and heating, avoid direct sunlight prohibit putting it out of door. Under this condition, the powder coating can be stored 6 months stably. Once over the storage time, it can be used after the new test results can meet your requirements. All of storage container should be re-sealed after using, and returned to the original package.

Health security

The container keeps seal. Shall not be close to the fire and heating, Avoid breathing powder. Storage areas ban smoking and eating, The operator need to wear anti-static shoes, keep grounded
