The relationship between film with light, semi-light and no light and actual use

The glossiness of the coating film refers to the reflective ability of the surface of the coating film, which is generally divided into three types: glossy, semi-glossy and matte. The glossiness of the coating film has the following relationship to the actual use:

1. Aesthetics: The glossiness of the coating film is one of the important indicators of the surface aesthetics. Glossy coatings have bright and bright surface gloss, and are generally used in occasions that require high decoration; semi-gloss coatings have moderate surface gloss, and are suitable for occasions that do not require high decoration; matte coatings have low surface gloss, Suitable for occasions where gloss suppression is required.

2. Durability: Gloss coatings are generally more prone to surface defects such as scratches and stains than matte coatings, affecting surface gloss and aesthetics, and therefore require more frequent cleaning and maintenance. The surface of the matt coating is relatively smooth and easier to clean, and is suitable for occasions that require long service life and easy maintenance.

3. Anti-fouling: The glossy coating has a high surface gloss, which is easy to absorb dust, grease and other pollutants, reducing the surface gloss and aesthetics; while the matte coating has a relatively smooth surface and is not easy to absorb pollutants, so it has better anti-fouling properties. Pollution performance.

4. Anti-corrosion: Glossy coatings are usually tighter than matte coatings and have better anti-corrosion properties, and are suitable for occasions requiring higher anti-corrosion protection.

Therefore, the glossiness of the coating film should be selected according to the specific use requirements and environment, and the appropriate paint and coating method should be selected to achieve better use effect and service life.

In addition, the glossiness of the coating film is also related to factors such as the type, quality, composition and additives of the coating. In general, coatings with high solid content are easier to form high-gloss coatings; at the same time, adding some special ingredients and additives, such as hardeners, thinners, leveling agents, etc., can also improve the gloss of coatings and surface smoothness. Low-gloss paints generally add some matting agents, fillers and other ingredients to suppress surface gloss.

Finally, in the actual coating process, the glossiness of the coating film is not only related to the coating itself, but also related to the coating process and conditions. Factors such as spraying pressure, nozzle aperture, spraying distance, coating film thickness, coating environment temperature and humidity will affect the gloss of the coating film. Therefore, when painting, it is necessary to adjust the painting process and conditions according to the characteristics of the paint and the specific painting requirements to obtain the desired glossiness of the paint film.
