What are the factors related to the gloss of paint?

In fact, the wetting and dispersing agent has a great correlation with the gloss of the coating. The crux of the problem lies in the particle size of the pigments and fillers after dispersion. The better the dispersion effect, the smaller the particle size, the better the distribution, and the higher the gloss. On the contrary, the gloss is lower.

The better the dispersion effect of the wetting and dispersing agent in the coating system, the higher the gloss of the coating after film formation. Therefore, a good wetting and dispersing agent is very important, and it is an additive that many customers pay special attention to when applying it, especially in areas with high gloss requirements such as leather, as well as a wide range of applications in water-based coatings.
Of course, the influencing factors of gloss are not only this one, but also the color and oil absorption of resins, solvents, pigments, and the smoothness and roughness of the paint film.
The first is the resin. Different types of resins have different gloss performance. For example, the gloss of UPE and UV systems is very high, while the gloss of low-hydroxy acrylic resins is relatively much worse. However, the gloss of the same type of resin is actually different, and it needs to be tested to be able to draw specific conclusions.

The second is the influence of solvents. If the solvent volatilizes too fast or too slowly, it will affect the flatness of the coating film, thereby reducing the gloss of the paint film; and if the leveling is good, it can form a smooth, flat and uniform paint film, and it will have a high gloss. .
Then comes the color and oil absorption of the paint. Each color has a different degree of light absorption and reflection. Black has more effect on light absorption, while white is reflective, so white has a higher gloss. The greater the oil absorption of the pigment, the worse the gloss.
As for the effect of the flatness and roughness of the paint film, it is relatively simple. The main reason is the optical principle. The flatter and smoother the place, the stronger the reflection, and vice versa.

In general, there are many factors affecting gloss, from all aspects. If you want high gloss, you must improve from the above-mentioned aspects. As long as all the influencing factors are adjusted, you can get a very high gloss; if the gloss is not enough, you can use the elimination method, one factor by one factor. Troubleshoot.
