Flamtard T (calcium hydroxystannate) flame retardant synergist is a non-zinc containing stannate that provides tin-based chemical functionality and is ideal for applications where zinc ions are not permitted or desired. It is insoluble in water and thermally stable (no weight loss) up to 220 °C. At higher temperatures (400 °C - 600 °C) calcium and tin ions can be volatilised or liberated from their structure to exert catalytic activity. 

​

Flamtard T (calcium hydroxystannate) is ideal for use in applications such as:

 

Coating Additives

​

• Smoke suppressant and flame retardant synergist for flame retardant paints.

 

Polymer Additives

​

• Smoke suppressant and flame retardant synergist with co-flame retardants. For polymer processing at temperatures below 220 °C.

• Co-additive in phosphate flame retardant containing polymer formulations to optimise char formation.
