Role of zinc oxide in pigment coatings

Zinc oxide has a high refractive index, has the ability to absorb ultraviolet light, and it has a strong coloring and covering power, but the appearance of pure white color, not chalked, has excellent light resistance, heat resistance effect.
Zinc oxide has a high refractive index, has the ability to absorb ultraviolet light, and it has a strong coloring and covering power, but the appearance of pure white color, not chalked, has excellent light resistance, heat resistance effect. It can form coordination compounds with carboxylate ions in paints and coatings, thus reducing the sensitivity of water in the coating. Therefore, zinc oxide can improve the weathering and chalking resistance of coatings and is suitable for exterior paints Zinc oxide has anti-mildew properties and can inhibit the growth and development of microbial strains of fungi. Usually porcelain, cans and buckets of paint coatings are used with small particle size and high content of indirect method zinc oxide; indoor paint coatings, latex paint coatings are commonly used needle-shaped direct method zinc oxide, so that the oil absorption value is higher, can improve the suspension performance.
Zinc oxide has the ability to make the product coating flexible, firm and impermeable to water, which in turn prevents rusting and corrosion of the golden hublot.However, it is not suitable for mixing with base materials that have more free acids, so as to form more zinc soap and make the paint coating sticky and not easy to brush. Zinc oxide is used in anti-corrosion or marine coatings to form a dense zinc-titanium chemical, which reduces the rate of further penetration of corrosive substances, mainly to play the effect of rust prevention.
Zinc oxide is an alkaline chemical that can form zinc soap with trace free fatty acids, which has the tendency to thicken paints and coatings, and decomposes when it meets inorganic acid or acetic acid.Paint and coating grade zinc oxide has small particle size and relatively large surface area, which has very strong adhesion and covering power, so as to enhance the efficacy of the paint pigment. Zinc oxide for paint and coating will eventually form a precipitate in the application, which has a certain effect of shielding ultraviolet light.
