Contax is a light-curing, self-etching and self-conditioning adhesive system that ensures a high level of protection from sensitivities – deliberately in two treatment steps.

• Secure long-term adhesion because of separate priming step
• Very technique tolerant, no postoperative sensitivities
• No additional etching

The Contax Bond penetrates the tooth structure prepared by the Primer and forms a »hybrid layer«. Solid adhesion with the subsequently applied restorative is thus achieved, ensuring a reliable and lasting bond.

Contax can be adapted to the filling material’s curing mode thanks to the Activator. That way, it can be used for light-curing restoratives on the one hand, but also for self-curing or dual-curing restoratives by adding the Activator on the other. The Activator is only needed when the material used is not light-cured.

The mixture consisting of one drop each of Activator and Bond is worked into the cavity. The Contax Activator ensures the bond in the interface between the self-curing or dual-curing material and the Bond.

Application of Contax with light-curing composites:

• Work in Contax Primer for 20 s.
• Work in Contax Bond for 20 s.
• Light curing required

Application of Contax with self- and dual-curing composites:

• Work in Contax Primer for 20 s.
• Mix Contax Activator and Contax Bond for 5 s.
• Work in the mixture of Contax Bond and Activator for 20 s.
• Light curing required
