What is film Gloss? How does it relate to film mass?

The so-called coating gloss can be interpreted as the specular reflection ability of the surface of the coating. If the surface is rough and the reflected light is messy, the gloss of the film layer will be low. If the surface is as smooth as a mirror, reflecting uniform light, the gloss will be high. In addition to special requirements (necessary semi-gloss, matt), paint products generally require a higher gloss.

As we all know, water and dust are the subject of various corrosive media. The grade of paint film gloss is actually a reflection of the roughness of the coating. This rough state means that water and dust with corrosive media are easy to accumulate on the surface. This not only affects the appearance of the coating, but also seriously reduces the durability of the coating.

Because the higher the gloss of the film layer, the smoother the surface is, which is beneficial to the film layer’s resistance to atmospheric and other corrosion factors. In addition, the high light buoyancy and strong reflection ability to sunlight also reduce the damage factors caused by numerous external rays. Therefore, general matt and semi-gloss coatings are suitable for clean air-conditioned computer rooms and laboratories; products, equipment, and steel structures that are often exposed to the atmosphere, sunlight, and rain erosion should use high-gloss coatings to exert their full potential. The real protection of paint.
