Uncover the formation process and material properties of powder coating matte coating
In the coating process, matte coating is used as a special surface treatment to give products a unique texture and appearance.
- Powder spraying is a common method for preparing matte coatings. In this paper, we will discuss in depth the preparation process of matte coatings formed by powder spraying and the characteristics of different materials.

Matte coating formation process
The process of preparing matte coatings by powder spraying consists of the following steps:
- Substrate preparation: First, the surface of the object to be coated needs to be treated, such as removing oil, rust and corrosion, etc., and proper cleaning and pre-treatment is carried out to ensure good adhesion between the coating and the substrate.
- Powder Coating: After the surface treatment, use a spray gun to evenly spray the matte powder coating onto the surface to be coated. Matte powder coatings are usually made up of pigments, resins, additives, etc., to which matting agents are added to achieve a matte finish.
- Curing and baking: After spraying, the object to be coated needs to be cured in an oven. At high temperatures, the powder coating melts, flows and reacts with the substrate to form a solid coating. At the same time, the matting agent will give the coating surface a matte finish during the curing process.
- Cooling and Inspection: After curing and baking, the object to be coated needs to be cooled and the quality of the coating inspected to ensure that the quality of the coating meets the requirements.

Differences in material properties
The matte coating formed by powder spraying may have some differences in material properties compared to ordinary coatings:
- Particle size: The addition of matting agents to matte coatings usually affects the particle size, making them slightly different from ordinary coatings. This may affect the surface texture and feel of the coating. 2. Composition ratio
- Composition ratio: The composition ratio in a matte coating may differ slightly from that of a conventional coating to meet the requirements for a matte effect. This may affect the gloss and durability of the coating.
- Coating Thickness: Since matte coatings usually have a certain graininess and texture, their coating thickness may be slightly thicker than normal coatings to ensure that the surface effect is achieved.
- Surface effect: The surface effect of matte coatings is significantly different from that of conventional coatings, presenting a matte texture, which is usually more understated and softer.
Despite some differences in material properties, the preparation process of matte coatings is basically the same as that of ordinary coatings, which is realized by powder spraying and curing. Therefore, in practical applications, matte coatings still have good durability and aesthetic effects, and can meet a variety of special coating needs.

Reveal why matte coating shows matte effect
As a special coating effect, matte coating presents a soft and low-profile appearance and is widely used in the surface treatment of various products. But why does matte coating present a matte effect? In this article, we will discuss in depth the reasons why matte coatings form a matte effect.
-
Addition of matting agent
The matting effect of a matte coating is mainly due to the addition of a matting agent to the coating. Matting agents are special additives that reduce the gloss on the surface of the coating, giving it a matte appearance. These matting agents will form tiny concave and convex structures after the coating has cured, causing light to be scattered from the surface of the coating, resulting in a matte effect.
-
Increased surface roughness
Matte coatings usually have a high surface roughness, which is closely related to their matte effect. During the curing process, the matting agent causes tiny bumps and particles to form on the surface of the coating, increasing the surface roughness. These tiny bumps and particles cause light to be reflected and refracted many times on the surface, thus reducing the reflectivity of the surface and giving it a matte appearance.
-
Scattering of light
The increased surface roughness of a matte coating results in multiple reflections and refractions of light on the surface, causing light to scatter evenly in all directions. Unlike smooth surfaces, the surface of a matte coating does not create visible reflections, but scatters light evenly into the surrounding space, giving a matte appearance.
-
Choice of pigments
Matte coatings are usually formulated with special pigments to achieve a matte effect. These pigments usually have high light absorption and scattering properties and can absorb and scatter light more effectively, thus presenting a matte appearance. By reasonably selecting pigment formulations, different degrees of matte effects can be realized to meet the needs of different products.
Conclusion
In summary, the main reasons for the matte effect of matte coatings include the addition of matting agents, increased surface roughness, light scattering and pigment selection. These factors interact with each other and together make the matte coating have a soft, low-profile appearance, giving the product a unique texture and aesthetic effect.
Through the introduction of the above, I believe the reader has a better understanding of the preparation process and material properties of the matte coating formed by powder spraying.
