ABSTRACT
A similar elaboration process is used for the two materials. Firstly, the uncured unfilled silicone RTV 141A (or RTV 3428A for the filled silicone) and 10/1 phr in weight of the curing agent RTV 141B for the unfilled silicone (or RTV 3428B for the filled silicone) are blended, and then degassed for 30 minutes in a vacuum chamber. The degassed liquid is injected by the way of a medical syringe in a closed mold to guarantee a constant thickness (2 mm) of the specimen. Finally, the material is cured by putting the mold in an oven at a temperature of 70°C during 4 hours.
