Zinc Oxide is fluffy, white powder with an exceptional variety of properties, it is produced by oxidation of metallic zinc vapor at elevated temperatures. By using French Process to produce our Zinc Oxide, the quality is a high degree of chemical purity and extreme whiteness and brightness.
/Application/
◣Rubber : Zinc Oxide occupies a unique position in rubber processing as it is outstanding in its effectiveness as an activitor of accelerators in the vulcanization process.
◣ Paint : As a pigment in linseed oil exterior house paints, Zinc Oxide shields the vehicle by absorbing the ultraviolet rays of the sun, toughen the film by formation of zinc soaps, and inhibits mold and mildew formation by its fungistatic properties. In metal priming paints the oxide aids suspension and improves water resistance through soap formation.
◣ Agricalture and Animal feed : Zinc is now regarded as an important nutrient in fertilizers and animal feed.
◣ Ceremics : Zinc Oxide reduces the coefficient of thermal expansion, imparts high brilliance and luster and high stability against deformation under stress. Such as glass systems, glazes, frits and thermoelements.
◣ Cosmetics : The optical and biochemical properties of Zinc Oxide and derivatives imparts special features to a variety of cosmetics. Preparation for cure of the hair and skin. in powders and creams it protects the skin by absorbing the ultraviolet sunburn rays, in burn ointment it aids healing.
◣ Ferrites : In many types of electronic devices, Zinc Oxide continues as an essential ingredient in the soft type of ferromagnetic materials for TV, radio, and tele-communication applications.
◣ Prepaint phosphate coatings : Zinc phosphate coatings applied to metal surfaces prior to painting have proven so effective in corrision resistance and paint holding properties, that they are widely used on new automobiles and refrigerators, etc.
◣ Plastics : The properties of plastic compositions can be improved by Zinc Oxide and its derivatives, such as aerylics, epoxides, nylons, polyesters, PVC, styrenes and urethanes.
◣ Photocoping : Zinc Oxide is increased in photoconductivity and semiconductor by special heat or doping treatments. Zinc Oxide also is greatly modified in optical properties to increase its absorption of light rays in the visible regions.
