This product does not contain arsenic, selenium, lead, hexavalent chromium, mercury, antimony, cadmium, and other heavy metals, and complies with RoHS requirements.

Storage conditions: Store in a dry and ventilated room at around 25C, avoid direct sunlight. Under this condition, the powder can be stored for 6-12 months. If it is overdue, it can be re-tested. If the results meet the requirements, it can still be used.

Exceptional Durability and Protection

This Primid-based powder coating offers remarkable durability, making it suitable for surfaces exposed to harsh weather and UV light. Its industry-standard formulation ensures excellent resistance to fading, chipping, and corrosion, extending the lifespan of coated metal components in demanding environments.


Versatile Application Methods

Apply the coating using either electrostatic spray or fluidized bed application for an even, high-quality finish. These methods ensure optimal powder adhesion to metal surfaces, resulting in superior coverage, minimal waste, and a consistent appearance.
