Category: Thermoset Powder Coating

Thermosett powder coating uses thermoset resin as film-forming material, adding curing agent for cross-linking reaction, and form an insoluble and infusible hard coating after heating. Since the resin used in the thermoset powder coating is a prepolymer with a lower degree of polymerization, the molecular weight is lower, the leveling of the coating is better, and it has better decoration, and the low molecular weight prepolymer can be cured after curing. The macromolecules form network cross-linked, so the coating has better corrosion resistance and mechanical properties.

Thermoset powder coating can be divided into the following categories:
1.Thermoset polyester powder coatings
2. Thermoset epoxy powder coatings
3. Thermoset polyurethane powder coatings
4. Thermoset epoxy polyester powder coating


1. Health and environmental protection.

All kinds of liquid chemical harmful additives added to achieve coating performance, such as film-forming, dispersing, wetting, leveling, anti-corrosion and mildew-proof additives, are omitted.

2. Convenient transportation and storage

Ordinary paints contain about 20-50% water or solvent, while powder coatings contain neither water nor solvent, and are completely solid, which is convenient and safe to transport. In addition, coatings containing water or solvents can be transported and stored at low temperatures. At 0°C, it tends to freeze, and powder coatings do not have this problem.

3. Paint smell

Compared with the odor residue of general traditional paint, powder coating has almost no odor.


Curing conditions have certain limitations.

What Is Acrylic Powder Coatings

Acrylic Powder Coatings

Acrylic powder coating powder have excellent decorative properties, weather resistance, and pollution resistance, and have high surface hardness. Good flexibility. But the price is high and the corrosion resistance is poor. Therefore, European countries generally use pure polyester powder (carboxyl-containing resin, cured with TGIC); (hydroxyl-containing polyester resin is cured with isocyanate) as a weather-resistant powder coating. Composition Acrylic powder coatings are composed of acrylic resins, pigments and fillers, additives and curing agents. Types Due to the different functional groups containedRead More …

The key properties of each generic type of thermosetting powder coating

thermosetting powder coating

Properties of each generic type of thermosetting powder coating Industrial finishes are custom formulated to individual and end-user requirements. Successful selection depends on a close working relationship between users and suppliers. Selection should be strictly on a demonstrated film performance basis. This is because the film performance of a thermosetting powder coating is completely dependent on the bake it receives in a particular plant, on a particular substrate, with a particular degree of cleanliness, and type of metal pretreatment. ManyRead More …

Thermosetting powder coating are much more widely used

Thermosetting powder coating are much more widely used

Thermosetting powder coating are applied by the electrostatic spray process, heated to the necessary temperatureand cured and are primarily composed of relatively high molecular weightsolid resins and a crosslinker.The formulation of thermosetting powders contain the primary resins:Epoxy,Polyester,Acrylic. These primary resins are used with different crosslinkers to produce a variety of powder materials. Many crosslinkers, or cure agents, are used in powder coatings, including amines, anhydrides, melamines, and blocked or non-blocked isocyanates.Some materials also use more than one resin in hybridRead More …

Thermosetting powder coating and thermoplastic powder coating

Polyethylene powder coating is a kind of thermoplastic powder

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”.They are applied as a dry material and they contain veryRead More …
