Transportation packaging

Carton packaging, lined with two layers of polyvinyl chloride plastic bags, net weight of each box is 20kg. Non-hazardous items can be transported in various ways, but should be kept away from direct sunlight, moisture and heat, and contact with chemicals.

Hygiene and safety

Operators should wear dust masks during use to avoid inhaling dust and minimize long-term contact between skin and powder coating. Paint attached to the skin can be washed with soap.

Powder properties

Specific gravity	1.4~1.8g/cm’ (depending on the formula and color)
Particle size	Depending on the purpose, the standard type has an average particle size of 35~40 microns, less than 10 microns of powder <10%, more than 100 microns of powder <0.5%.
Storage stability	Outdoor matte powder coatings should be stored in a dry, ventilated room below 30°C, and avoid direct sunlight. If stored in an air-conditioned room, the powder must be stored at room temperature or the same (temperature) as the spraying equipment before use to avoid moisture. Under this condition, the powder can be stably stored for 6 months. If it exceeds the period, it must be re-tested. If the result meets the requirements, it can still be used.
