A thin layer of Colténe adhesive ensures adhesion of tray material to the tray sides.

Coltène Adhesive is an autoclavable adhesive for all AFFINIS impression materials and serves as an adhesive bonding agent between this material and the PRESIDENT disposable impression trays AC. Separation of the impression material during removal from the mouth can therefore be prevented. The special spray nozzle provides application with a uniform, thin layer without becoming clogged. Coltène Adhesive AC was specially developed for the autoclavable system (AFFINIS impression materials, PRESIDENT disposable impression trays AC).
