But have you ever had the phenomenon of paint mold? Gray or brown molds are often seen, which not only affects the appearance, but also easily breeds bacteria, causing adverse effects on human health. To deal with this phenomenon, Kazon fungicide is generally used.

1. What are the main components of paints and coatings? The main components of 　　 paint include the following five parts: 　　Oil: including dry oil and semi-dry oil, is one of the main film-forming substances. 　　 Resin: Including natural resin and artificial resin, it is also part of the main film-forming material. 　　 Pigments: Including coloring pigments, extender pigments and anti-rust pigments. There are quite a variety of specific types, and they are secondary film-forming substances. 　　 Thinner: Including solvents and diluents, used to dissolve the above substances and adjust the consistency, as an auxiliary film-forming substance. 　　 Accessories: including drier, curing agent, plasticizer, moisture-proof agent. It also belongs to auxiliary film-forming substances.

The upstream industries of the coating industry include the manufacturing of chemical raw materials such as resin, solvent, pigment, filler and additives, while the upstream of chemical raw materials such as resin and solvent is the petrochemical industry. The downstream of the coating industry is mainly construction, furniture, automobile, household appliances and other production enterprises and home decoration market.

Water-in-water coatings contain many components, which are prone to mildew under the influence of humidity and temperature increase. Among them, organic polymers such as cellulose (natural macromolecule) and PVA are more susceptible to mold and deterioration, so anti-corrosion is long-term stability of coatings.
