Thermosetting Low-Temperature Curing Powder Coating

Thermosetting Low-Temperature Curing Powder Coating About

1. Product Overview

Low-temperature curing powder coating is a newly developed product designed specifically for applications where high-temperature baking is unsuitable.

It not only retains the characteristics of conventional powder coatings but also reduces the curing temperature to 140160, significantly expanding the application fields of powder coating technology.

4. Safety and Hygiene

This product is non-toxic, environmentally friendly, and non-flammable. However, appropriate protective measures should be taken to prevent excessive inhalation during construction and application.

5. Packaging, Storage and Transportation

The product is packed in cardboard cartons with polyethylene inner bags.

Net weight: 25 kg per package.

Store in a dry, ventilated, and clean environment below 30 for up to 12 months. Keep away from fire sources and heating equipment.

After opening, any unused powder must be resealed properly to prevent moisture absorption from the air.

Protect from direct sunlight and rain. When the ambient temperature exceeds 35, appropriate insulation measures should be taken during storage and transportation.

Efficient Low-Temperature Curing

Our powder coating offers significant energy savings by curing at temperatures as low as 120C to 140C, making it ideal for both newly manufactured and sensitive substrates. Its rapid curing feature reduces overall production time without compromising coating performance or durability.


Durable Protection and Versatile Appearance

Built for industrial environments, this coating excels in resisting corrosion, chemicals, and physical impacts. It is available in various finishes-matte, semi-gloss, and glossy-providing both protective qualities and the option for a wide spectrum of vibrant, customizable colors.


User-Friendly Application and Reliable Storage

This thermosetting powder is supplied as a fine powder (30-40 microns average size), ensuring smooth application via electrostatic spray or gun. Proper storage below 25C in a cool, dry setting guarantees product integrity and maintains a 12-month shelf life.
