Series 700

Fluid poly-addition silicone rubber with high precision (linear shrinkage < 0.1%) are used in laboratory models duplication in the dental industry. They have high fluidity, easy degassing, fast cure, excellent details reproduction, excellent dimensional stability in the time, excellent compatibility with phosphate coatings, polyurethane resins and plasters.

Make sure that the model to duplicate is perfectly clean and dry. Before using shake well the bottles of part A and part B. Mix exactly the same quantity of part A and part B. If the proportions are not exactly, the curing times and the final properties can be different. Mix about a minute until a homogeneous colour is obtained. Strain from 20/30 cm in height at the side of the model to remove any air bubbles. After about 30’ demould the model using a jet of compressed air. The curing speed is influenced by the temperature. We recommend to work in an isothermal place at 23°C. Higher temperatures accelerate the curing times, lower temperatures reduce them. Some inhibitions to vulcanization process may occur when the silicone rubber get in contact with amines, plasticines, metal salts, sulphur, tin catalyst and poly-condensation silicone rubbers. To avoid any inhibition problems, we recommend a preliminary test for the compatibility of the silicone on the material to duplicate. The products, when stored under appropriate conditions, are stable and usable for 12 months. We suggest to keep the products in their original packaging, well-closed at a temperature between +7°C and +27°C, in well-aired places. Close always the bottles after use. Do not reverse the cap.
