This is our classic 1:1 silicone. This auto-curing putty with a shore hardness of 70 has excellent dimensional stability, accurate detail reproduction, and no distortion in the anaxFORM flask. Even high temperatures (200 0C) cannot harm this silicone. Accuracy and high performance! It was developed for the counter technique in the anaxFORM flask, for rims of temporary restorations, mock-ups, fixation, damming, exact transfer keys, and for checking rims for planning.
