71-11 is a low viscosity addition cure silicone that may be used to make molds for soap, candles, and delicate resin parts. Because of the low viscosity of 71-11 it does not have to be degassed. If you are making molds for resin that will require pressure casting the silicone will need to be degassed, otherwise micro bubbles will occur in the rubber causing small imperfections in the pressure cast resin.
