Product details

Product description

This series of products is based on saturated hydroxyl polyester resin and TGIC curing agent as the main base materials, and is a thermosetting powder coating with excellent weather resistance designed for outdoor materials used in construction.

Product characteristics

High weather resistance, strong mechanical properties;

Excellent water boiling resistance, excellent corrosion resistance;

Good polishing, good construction adaptability and high powder coating rate;

Excellent resistance to excessive baking.

Special effects

Various textures, thermal transfer, metal, pearlescent effects and mixed colors, etc.

Application areas

Specially used for spraying of architectural aluminum alloy profiles.

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 gravity1.2~1.8g/cm³ (depending on the formula and color)
Particle sizeDepending on the purpose, the standard type has an average particle size of 20~45 microns, less than 10 microns powder <8%, greater than 70 microns powder <20%
Volatile matter<1%
Softening point60~95℃ varies depending on the color and gloss
Storage stabilityPolyester/TGIC powder coatings should be stored in a dry and ventilated room below 35℃, 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 stored stably for 12 months. If it exceeds the period, it must be re-tested. If the result meets the requirements, it can still be used. Note: For low-temperature curing types and powders with a gloss of less than 40% (60°), the storage temperature should be below 30℃.
