Coating additives are a kind of additives in coatings, which are used to improve the performance, quality and construction characteristics of coatings. There are many kinds of coating auxiliaries, which can be divided into the following categories according to their functions and uses:
1. dispersant: used for dispersing pigments and fillers, preventing them from precipitating and agglomerating in coatings, and improving the dispersion and uniformity of pigments.
2. Thinner: Used to adjust the viscosity and fluidity of the coating so that it is easy to apply and spread, and at the same time, it can speed up the volatilization of solvents.
3. stabilizer: used to improve the stability of the coating, prevent it from delamination, caking and other phenomena in the process of storage and use.
4. drying agent: used to accelerate the drying speed of coatings, reduce construction time and improve production efficiency.
5. preservatives: used to prevent the paint from mold, deterioration and microbial attack, to extend the service life of the paint.
6. capillary protective agent: used to improve the permeability and weather resistance of coatings, preventing moisture, chemical substances, etc. from penetrating into the interior of the coating and causing peeling, cracking and other problems.
7. Discoloration agent: Used to change the color and gloss of the coating to achieve different decorative effects.
8. Hardener: Used to enhance the abrasion resistance, scratch resistance and chemical corrosion resistance of the coating, and improve the hardness and durability of the coating.
9. Thickener: used to increase the thickness and adhesion of the coating, improve the coverage and hiding power of the coating.
10. antistatic agent: used to reduce the static adsorption on the surface of the coating, prevent the adhesion of dust and dirt, and keep the coating clean and glossy.
In general, coating auxiliaries play a vital role in the production and use of coatings, which can not only improve the performance and quality of coatings, but also enhance the construction efficiency and decorative effect of coatings. Therefore, when selecting and using coating auxiliaries, it is necessary to make reasonable matching and adjustment according to the type, use and environmental requirements of the coating to ensure that the coating has good performance and
