SternVantage® Putty

1. What is the composition?
Addition curing polyvinyl siloxanes, silicon dioxide, food pigments, additives, platinum catalyst.

2. What is the shelf life?
The shelf life is 3 years from the date of manufacture.

3. What is the difference between the SternVantage ® Putty Regular and Putty Soft?
The SternVantage® Putty Regular has a Shore A hardness of 73 while the Putty Soft has Shore A hardness of 65. We recommend that the Putty Regular be used for the double impression technique and the Putty Soft be used for the single impression technique.

4. A "platinum catalyst" is a component of the Putty. What is its purpose?
The presence of this component increases the stability of the material and increases the accuracy of the material. It is found in all SternVantage® impression materials. The platinum catalyst is the reaction partner for the base material. Its purpose is to induce the reaction kinetics. The final, set impression material is highly stable.
