The tray adhesives Fix and Silfix from Dentsply ensure strong retention of impression material, be it alginates or A-silicones, inside the tray. Fix Adhesive (liquid and spray) are solvent-based adhesives which increase the adhesion between alginate impression materials and the impression tray surface. Fix Solvent is a spray to remove any remaining adhesive from the impression tray after impression taking and casting.

Silfix, the tray adhesive for A-Silicone impression materials, is a polysiloxane-based adhesive. Silfix is painted on the inner surface of the impression tray prior to application of the mixed impression material, in order to increase the adhesion to the tray of conventional, quadrafunctional and hydrophilic A-silicone impression materials. Both Fix and Silfix Adhesives need to be applied in a thin layer ensuring economy due to less material wastage. This thin layer produces an extremely strong adhesion. Fix solvent is available for easy removal of the remaining adhesive.
