Acetone
Acetone acts as a water chaser and enables a fast and secure evaporation of water, which is required for a durable and consistent bonding system.
Water is always present during cavity preparation and is also an important component in adhesives to achieving efficient etching of the tooth. After application and etching, both the water and solvent have to be optimally removed to enable efficient adhesive layer polymerisation throughout the light curing process.
Acetone as a solvent, with very high air pressure, supports this evaporation process. Therefore this acetone/water system ensures an optimal polymerisation result and thereby maximising bond strength.
