Starbond CoS Powder

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.
