Zinc oxide is white powder, with good hiding power and tinting power, widely used in printing & dyeing, rubber, coating, ceramics, feeds, cosmetics, pharmacy,ink, cable, electronics, phosphor, catalysts. 1. The product has small particle size, large specific surface area, strong adhesion and hiding power, which can greatly improve the efficacy of the coating. 2. The product has a small proportion and is not easy to form precipitation in the use or final product. 3. The product also has the function of shielding ultraviolet rays, and can play an anti-aging role in the coating.
Zinc Oxide USP is mainly used in food industry as a dietary ingredient and as a nutrient. Zinc is an important antioxidant nutrient. It is necessary for protein synthesis, wound healing, for blood stability, normal tissue function, and aids in the digestion and metabolism of phosphorus. It also governs the contractility of muscles and maintains the body's alkaline balance. Zinc Oxide is also used in a variety of products like plastics, ceramics, glass, cement, rubbers, paints, pigments, lubricants, adhesives, sealants, batteries, ferrites, flame-retardant, and bandages. It is commonly used in personal care products like baby powders, diaper rash creams, calamine creams, antiseptic ointments, and anti-dandruff shampoos and sunscreens. It is used as an additive in the production of concrete, and as an additive in food products (breakfast cereals).USP, or United States Pharmacopeia, grade chemicals comply with the standards of the United States Pharmacopeia and National Formulary (USP-NF). USP Grade chemicals are fit for use in food, drugs, and medicines. They are subject to stringent testing and are typically required to have the highest level of purity.

Zinc oxide is a largely inert, white compound which is used very widely as a bulking agent or filler, and as a white pigment. It is found in some rubber, glass and ceramic products, and finds use in the chemical industry as a catalyst. It is also used in paints as a corrosion inhibitor and for mildew control.
Zinc oxide of different grades.
