Low temperature curing polyester powder coating

Low temperature curing polyester powder coating About

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.

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 gravity	1.41.8g/cm (depending on the formula and color)
Particle size	Depending on the application, the standard type has an average particle size of 3540 microns, less than 10 microns powder <10%, greater than 100 microns powder <0.5%
Storage stability	Polyester/Primid type powder coatings should be stored in a dry, ventilated room below 35C, 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.

Curing conditions	180/10 minutes is recommended, and it can also be designed according to user needs: 160C/15 minutes, 170/12 minutes, 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.

Efficient Low Temperature Curing

This polyester powder coating is specifically engineered for low temperature curing, requiring just 140C to 160C to achieve a fully crosslinked, durable surface. It helps reduce energy consumption and is suitable for heat-sensitive substrates. The consistent curing results in robust films with excellent adhesion properties.


Vivid Color and Finish Options

Choose from multiple RAL shades or request custom colors to fit your specific project. The powder is available in low, semi, or high gloss finishes, ensuring flexibility in aesthetic and functional design for industrial applications.


Exceptional Performance Outdoors

Engineered for superior weatherability and corrosion resistance, this coating excels in outdoor and harsh industrial settings. It forms a protective barrier that safeguards metal surfaces from environmental challenges, maintaining visual appeal and structural integrity over time.
