Can powder coating be matte finish?

Time:2025-10-28 views:

Yes, powder coatings can achieve a matte finish by adding a matting agent. Matting agents modify the microstructure of the coating surface, reducing light reflection and creating a soft, non-reflective effect. Of course, matte powder coating can also be used directly to achieve a matte finish, which is more convenient. Let's learn more about matte powder coating.

1. Matte Powder Coating Technology and Characteristics

1.1 Advantages of Matte Powder Coating

• VOC-free and recyclable

• Increases the brightness of lamps

• Reduces the use of light sources for the same wattage

• Easier processing and can be used in conjunction with regular powder coatings

• Lower cost

1.2 Smooth and Matte Powder Coatings

Depending on the matting method used, matte powder coatings can produce a smooth, silky finish or a slightly rough, but overall smooth, matte finish.

1.2.1 Smooth and Delicate Matte Coating

This type of coating has a silky, smooth finish. This surface effect is often achieved through chemical matting, which inevitably sacrifices some of the product's weather resistance and is relatively expensive.

This type of matte powder coating often uses a matting agent, which is quite delicate and less resistant to weathering stresses such as wind, sun, and rain, resulting in reduced weather resistance.

1.2.2 Smooth, Matte Coating

This type of outdoor matte powder coating can achieve a gloss of 10 Gs or less. While it doesn't have a perfectly smooth, delicate microscopic surface, its smooth, matte-like effect is unique—and it lacks the bumpy texture of grained powders! Much like outdoor water-reflective powder coatings, this product has always been a favorite, and there are always those who love it!

This smooth, matte-like matte powder has become a cult favorite in the market, with a loyal following! Companies that utilize this powder coating design and manufacturing technology typically treasure it like a treasure. Their products are remarkably stable both in production and spray application (though some consider them unstable and uncontrollable, resulting in poor surface finish). They also offer exceptional weather resistance, achieving color stability for up to 15 years outdoors.

With a wide gloss adjustment range of 10 to 30 gs and a stable gloss range, the current minimum gloss is 10 to 15 gs. Companies that master this matte powder gloss adjustment technology generally possess considerable technical expertise.

1.3 Matting Techniques

The matting methods used for liquid coatings like oil-based and water-based paints are often ineffective for matte powder coatings. These coatings often require specialized matting methods.

1.4 Two-Part Matte Powder Coatings

Matte powder coatings have long been a favorite among many customers. However, in today's fiercely competitive market, the high cost and price of matte powder coatings make them prohibitively expensive. Two-component matting technology is used to reduce powder coating costs, making the product more economical. This technology utilizes carefully selected raw materials and refined formulas, eliminating the expensive use of matting agents. This reduces powder coating costs to levels comparable to those of outdoor flat powder coatings. This technology significantly reduces powder coating costs, passing on the resulting price savings to customers, making two-component matting powder coatings more economical.

1.4.1 Excellent Weatherability

Using two-component matting technology, which eliminates the traditional matting agent-based matting technology, allows for even better weather resistance in outdoor matte powder coatings. Designed weatherability ranges from 3-5 years for standard outdoor products, to 7-8 years for standard weatherability, 10 years for high weatherability, and even up to 15 years for super weatherability.

1.4.2 Excellent Product Stability

Two-component matting technology eliminates the need for matting agents in product formulation design, improving product storage stability and spray stability. This significantly extends the shelf life of powder coatings to over two years.

1.4.3 Lower Gloss

Outdoor matte powders using two-component matting technology achieve a gloss reduction of 10-40 gs (measured at 60 degrees), a similar gloss range to fluorocarbon coatings, resulting in a soft, optically smooth finish.

1.4.4 Faster Curing Speed ​​Improves Powder Coating Spraying Efficiency

Using two-component rapid curing technology, compared to two-component TGIC matting technology, the slower-curing component fully cures within 15 minutes at 200°C. This helps achieve the "200°C 15-minute" baking cure standard for two-component matte powder coatings, improving spraying efficiency. However, two-component TGIC matting technology reduces matte powder coating application efficiency because the slow-reacting component requires at least 15 or 20 minutes to cure at 200°C. Furthermore, without full cure, it is difficult to ensure the coating's weather resistance and salt spray resistance, making it difficult to achieve an extended service life.

1.4.5 Thin Coating Achieves

Using "two-component matting" technology, powder coatings can be applied at normal film thicknesses (60-80 microns) or less, while still maintaining an excellent film appearance, helping to reduce powder coating costs.

1.4.6 Excellent Environmental Performance

Henan Chuangqi Paint Co., Ltd. uses "non-TGIC" curing technology, resulting in matte powder coatings that are TGIC-free. Therefore, this type of powder coating is more environmentally friendly and beneficial to the health of production workers.

1.4.7 Excellent Economical Efficiency

Two-component matting technology eliminates the traditional matting agent-based matting technology. This eliminates the high cost associated with matting agents, making the product more economical. Ultimately, the cost and selling price of two-component matte powder coatings are close to or lower than those of conventional glossy powder coatings. This makes the product more affordable and eliminates the need to pass on higher product costs to downstream customers. Therefore, two-component matte powder coatings are more economical.

1.4.8 Appearance

Powder coatings produced using two-component matting technology exhibit excellent smoothness, a microscopically matte (no bumps) feel and visual experience, and a soft, elegant sheen.

2. Advantages and Disadvantages of Matte Powder Coatings

2.1 Comfort and Environmental Protection

For large public buildings, glare has always been a problem. Researchers are constantly striving to create a more comfortable environment, using new materials to soften the light in spaces. The key is transforming specular reflection into diffuse reflection. Diffuse reflection refers to the uniform reflection of light within a semicircular area above the coating surface, with the same amount of reflection at all angles. This light effectively enhances the coating's surface brightness. Under the same lighting power, this improves lighting efficiency, reduces energy consumption, and protects the environment, contributing to improved productivity, work efficiency, quality of life, and overall health.

Matte powder coatings typically refer to flat powder coatings with a glossiness range of 10 to 40 gs (gloss units). Powder coatings with a glossiness below 10 gs are considered matte, while those above 40 gs are considered soft or glossy. Matte powder coatings in the 10-40 gs range offer exceptionally good overall performance and a wide gloss range, making them popular with the public.

2.2 Outdoors Absorb High Heat

Matte powder coatings applied to furniture easily absorb heat and UV rays from the sun. Since sunlight doesn't reflect off the paint, it can cause the paint to heat up. Matte black paint, in particular, can cause the car body to heat up abnormally in the summer heat. However, the lack of strong glare protects the delicate eyesight of children. It's also impervious to scratches, marks, and minor abrasions, making it easy to maintain.

2.3 Excellent Weathering Resistance

Overall, outdoor matte powder coatings offer excellent weathering resistance, with a guaranteed gloss and color retention of up to 15 years. The coating film integrity can last for over 20 years.

2.4 Average Corrosion Resistance

Average, it's not suitable for high-corrosion applications.

3. Product Applications

Matte powder coatings offer excellent weathering resistance and can be used in applications requiring a low gloss finish, such as aluminum curtain walls, aluminum profiles, aluminum gussets, outdoor leisure furniture, automobiles, and subways. They keep the surface looking like new for up to 15 years! Matte coatings can effectively reduce or prevent reflected glare, reducing the discomfort it causes to the naked eye and softening the light within a space.

4. Summary

Matte has gradually permeated every corner of our lives! It's also a fashion statement. Unlike the dazzling luxury of bright light, matte, in a subtle and restrained way, conveys a unique sense of luxury, adding a sense of maturity and stability, adding a touch of simplicity and elegance to this vibrant world.
