Premium Grade Zinc Oxide

CHEMETAL (M) SDN BHD is one of the few manufacturers of premium grade Zinc Oxide(ZnO) in ASEAN.

Our premium grade zinc oxide is called Platinum Seal which has purity level of 99.9% and above, and is used in various applications and industries that need high purity zinc oxide such as pharmaceuticals, cosmetics, ferrite, dispersions, wet latex, zinc strearate manufacturing and more.

Apart from premium grade zinc oxide, other grades are also available namely, White seal (99.8%) and Red Seal (99.5%), which are widely used in paints and coatings, ceramics, glassware, animal feed, tyres and many other applications.
