Product details

Product Description

This series of products uses saturated polyester resin and Primid curing agent as the main base material to make thermosetting powder coatings.

Product Features

Good adhesion and good mechanical properties;

Smooth coating film and high gloss;

Good chemical and corrosion resistance;

Higher storage stability and shelf life than TGIC type.

Special effects

Various wrinkles, metal, pearlescent effects and mixed colors, etc.

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 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.

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 application, the standard type has an average particle size of 35~40 microns, less than 10 microns powder <10%, greater than 100 microns powder <0.5%
Storage stabilityPolyester/Primid type powder coatings should be stored in a dry, ventilated room below 35°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 more than 12 months. If it is exceeded, it must be re-tested. If the result meets the requirements, it can still be used.
