Matte powder coatings are not defined by temperature; a gloss level between 10-40 GU falls into the matte category.
1. Definition of Matte Finish
The key indicator for determining whether a powder coating is matte is the surface gloss level. When the gloss level is between 10 GU and 40 GU, it can be classified as matte. Its surface can exhibit a smooth or finely textured frosted feel. This characteristic is not directly related to high or low processing temperature.
2. Visual Effects of Matte Finish
The most significant characteristic of matte finish (also known as matte or desmear) is low reflectivity, specifically manifested as:
No obvious specular reflection under light, avoiding glare;
Soft and understated colors, less prone to light pollution when used over large areas;
A frosted, textured feel on the surface, enhancing the product's premium and artistic appearance.
3. Practical Application Advantages of Matte Coatings
In industrial and residential settings, matte powder coatings are commonly used for:
Metal components and furniture surfaces, reducing visual interference from metallic reflections;
Electronic device casings, improving grip and reducing fingerprint residue;
Building exterior wall decoration, creating a low-key and elegant style through a soft texture.
