UCA LANKA PVT LTD

A distinguished manufacturer and exporter of quality Zinc Oxides. UCA Lanka Pvt. Ltd uses the most advanced manufacturing technology for the production of zinc oxides. We have developed our core competence in the field of exporting & importing of zinc oxide and zinc dross. These technologies have been developed from years of experience in zinc oxide production and from improvements in response to the progressive changes in requirements from the customers.

- Zinc oxide is used to manufacture glazes and acts as an opacifier or whitener.

- Zinc oxide's low coefficient of thermal expansion improves resistance to thermal and mechanical shock, most notably in glass.

- In the frit industry, zinc oxide enhances colour and clarity.

- Zinc oxide's high refractive index makes it an excellent raw material for manufacturing optical glass.

- Zinc oxide is used in the varistor and ferrite industries to manufacture ceramic components which protect against lightning and voltage surges.
