Series 800



They are putty poly-addition silicone rubber which cures at room temperature with a low shrinkage (linear shrinkage about 0.1%). The high final hardness gives excellent dimensional stability, details reproduction, resistance to deformation. They are used for the production of masks for the manufacture of skeletally and temporary prosthetics.

How to use

Make sure that the model to duplicate is perfectly clean and dry. 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 the mass energetically with your fingertips for about 30” until a homogeneous colour is obtained, without stripes. Then model the mass as required. You have about 2’ to work with the mass, including mixing time, at room temperature. It takes 5’ for the demoulding. 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 18 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 caps after use. Do not reverse the caps. Put always the counter-caps in their packaging.
