Zinc oxide is Mainly used in the production of high-grade paints, coatings and other products and coating intermediates and a commonly used chemical additive widely used in the production of plastics, silicate products, synthetic rubber, lubricating oils, paints, ointments, adhesives, foods, batteries, flame retardants and other products. Zinc oxide has large band gap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is used in liquid crystal displays, thin film transistors, light-emitting diodes and other products in the semiconductor field.
2. Major Features of Product:
•Small particle size, large surface area, strong adhesion and hiding power, greatly improving the efficacy of the coating
•The coating grade zinc oxide has a small specific gravity and is not easily precipitated in use or in the final product.
•The coating grade zinc oxide also has a certain role of shielding ultraviolet rays, and can play an anti-aging effect in the coating..
• Plastic & Rubber Industry
