Product details

Product description

This series of products is made of saturated polyester resin and isocyanate curing agent as the main base material.

Product characteristics

Good adhesion and good mechanical properties;The coating is full and smooth with high gloss;Excellent weather resistance.

Application areas

Suitable for coating of various products exposed outdoors for a long time: such as household appliances, architectural aluminum profiles, transportation facilities, stadium facilities, courtyard facilities, etc.

Transportation packaging

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

Health 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 gravity1.4~1.8g/cm’ (depending on the formula and color)
Particle sizeDepending 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 stabilityPolyurethane 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 not 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 more than 12 months. If it is exceeded, it must be re-tested. If the result meets the requirements, it can still be used.
