In the design of coating formulations, zinc oxide can provide designers with many high-performance coating formulations. Zinc oxide is an alkaline compound that can react with trace amounts of free fatty acids to form zinc soap, which has a tendency to thicken the paint and will dissolve when it encounters inorganic acids or acetic acid. Mainly used in the production of high-end paints, coatings and other products and coating intermediates.
Characteristics and functions:
.Small particle size, large specific surface area, strong adhesion and hiding power, greatly improving the efficacy of the paint.
.The specific gravity is small and it is not easy to form precipitation during use or in the final product.
.It also has a certain effect of shielding ultraviolet rays and can play an anti-aging role in coatings. This product is also a traditional metal preservative.
Packaging and transportation:
, double-layer packaging with inner plastic and outer weaving
, standard package weight:
, can also be packaged according to user needs
, during transportation and storage Pay attention to moisture-proof
Zinc oxide has excellent mildew resistance and the effect of controlling microbial fungi.
Zinc oxide has a high refractive index and the ability to absorb ultraviolet light. Its tinting power and hiding power are second only to zinc barium white and zinc oxide. However, if the color is pure white and not pink, it has good light resistance and heat resistance: it can be combined with paints. The carboxylate ions in the zinc oxide form a coordination compound, which can reduce the sensitivity of water in the coating film. Therefore, zinc oxide can improve the weather resistance and powdering resistance of the coating film and is suitable for exterior wall coatings. Zinc oxide makes the product coating flexible, strong, and impermeable, thereby preventing metal corrosion.
Zinc oxide used as if or in ship pictures can form lethal iron-zinc compounds that reduce the rate of further penetration of corrosive media. Mainly plays the role of rust prevention.
Generally speaking, ceramics and can coatings use indirect method zinc oxide with small particle size and high purity; indoor coatings and latex coatings use needle-shaped direct method zinc oxide. The oil absorption value of the index finger has been taught to improve the suspension performance.
When zinc oxide is used in latex paint, if the amount is too large, the viscosity of the paint will be greatly increased and the stability of the paint will be reduced. Stability can be achieved by selecting the appropriate dispersant quality, base material quality, value, original viscosity, etc. coating formula.
