DUR-LAB-Sil® & Hardener®

DUR-LAB-Sil is an extra tough silicone (putty), specially designed for the use in the dental laboratory.

Dur-Lab-Sil is based on condensation-curing silicones. Thanks to the very high temperature-stability it is particularly suitable for the replica denture technique. An easy handling is guaranteed because Dur-Lab-Sil is non-sticky, dimensionally stable and heat-resistant.

DUR-LAB-Sil has to be mixed with DUR-LAB-Sil Hardener liquid or with DUR-LAB-Sil Hardener paste.
