Product Description
Product Details
Introduction
① Coating additives: Smoke suppressants and flame retardants used in flame-retardant coatings. Used in transparent conductive oxides, used in the manufacture of thin films for solar cells, touch screens, and energy-saving glass.
② Polymer additives: Smoke suppressants and flame retardants, acting synergistically with co-flame retardants. Added as a synergistic additive to polymer formulations containing phosphate flame retardants, it promotes char formation and provides a flame retardant effect. Zinc hydroxystannate is used for polymer processing at temperatures below 180°C. Zinc stannate has no restrictions.
③ Process chemicals: Solid lubricant additive in friction materials.
