RTV Silicone Rubbers

RTV silicone rubber is a two-part liquid silicone which can be used to create flexible silicone molds for casting, or for making flexible silicone components themselves.

Our CS25 Condensation Cure Silicone Rubber is an easy-to-use and cost effective tin-cure silicone is ideal for making basic silicone molds for fast-cast polyurethane (such as our Xencast P2), especially if a degassing chamber is not available. Our AS40 Addition Cure Silicone Rubber is a higher performance platinum-cure silicone rubber recommended when making molds for clear casting resins or making silicone components themselves.

Both types of silicone can be pigmented using our silicone colour pigments. AS40 can be turned into a brushable silicone, suitable for glove molding, with the addition of a thixotropic additive.
