Starbond CoS Powder
Starbond CoS Powder is based on the proven dental bonding alloy Starbond CoS. The user can thus continue to work in a system with the same alloy components and the same composition, as well as the same positive processing characteristics.
The manufacturing process of the powder ensures the best possible flowability.
- No cooling phase required, depending on ceramics
- Excellent veneering
- A CTE of 14.4 permits great flexibility in ceramic selection
- Biocompatible
- Extremely corrosion resistance
- CE certfied
