Zinc Oxide
The ceramic industry uses zinc oxide for many diverse applications. Ceramic tiles and frit enamels are probably the most well known. However, zinc oxide also plays an important role in ophthalmic glass. In decorative tiles, zinc oxide improves the brilliance of clear and coloured glazes. It is commonly used as a constituent in opal and alabaster glazes, improving their lighting properties and chemical resistance.
The fungicidal and mildicidal properties of zinc oxide make it an important ingredient in many paint formulations. Coatings formulated with zinc oxide provide biocidal functions, improve colour retention and the durability of the film under varying climatic conditions.
Rubber products represent the largest market for zinc oxide.From rubber tires and general rubber to latex compounds, zinc oxide is used as an activator in the vulcanization or curing process. It also adds strength to rubber compounds, improves their resistance to heat and abrasion and helps guard against ultraviolet degradation.
All of our Zinc Oxide products get produced locally via American Process (or direct) and French Process (or indirect) that entail melting and vaporizing zinc metal. American Process uses oxidised materials such as metallic zinc ash and French Process requires pure or secondary zinc metal like zinc dross and zinc ingot as the raw materials.
90% of our zinc oxide products have been already exported to the partners located in Europe, Middle East and Asia and the rest get sold to the manufacturers located in Turkiye. Main customers are ceramic, porcelain, rubber, tire, paint, fertilizer manufacturers. Our annual production capacity is around 17000 tons.
