Zinc Stannate

• CAS: 12036-37-2
• Catalog Number: ACM12036372
• Category: Other Products
• Molecular Weight: 232.06
• Molecular Formula: ZnSnO3
• Description: Zinc Hydroxystannate and Zinc Stannate are active smoke suppressants as well as flameretardants. Their superior performance is because of their dual phase mechanism. In addition to exhibiting vapor phase action, similar to Antimony Trioxide, they also exhibit condensed phase action during which they act as excellent char promoters. The condensed phase action of Zinc Hydroxystannate and Zinc Stannate enhances the formation of a thermally stable carbonaceous layer at the expense of aromatic, volatile and flammable products. These products exhibit synergy with Zinc Borate, Ammonium Octamolybdate and Antimony Trioxide.
• Synonyms: ZnSnO3
• Density: g/cm³
