Kulzer Xantopren condensation silicone, 140 ml tube

Low-viscosity relining material – 1 x 140 ml tube.

Optosil Comfort/Xantopren: condensation silicone (silicone paste + activator) that marks the historical beginning of precision impressions. It was created to allow recording beyond the preparation and to extend the period of dimensional stability. Optosil/Xantopren introduced the concept of elastic memory, whereby the material displays its elasticity by deforming during tray removal, but quickly (30 min.) regains its original shape.

Over the decades, Optosil Comfort and Xantopren have been, and still are, a benchmark for clinicians. Optosil Comfort and Xantopren introduced the double impression technique; the balance between the final consistency of Optosil Comfort and the high flowability of Xantopren VL made it easy to record excellent detail. With both Optosil Comfort and Xantopren, clinicians can modify the setting time according to the amount of activator used. This implies that if, in particular cases, more activator than indicated in the instructions has been used, dimensional stability is compromised, so the model must be poured immediately after full recovery of elastic memory (30 minutes).

Over the past year Kulzer has updated its Optosil/xantopren Activator Universal Plus, modifying some components in anticipation of a European regulation aimed at reducing the possibility of certain chemical components coming into contact with the human body.
