Our clear RTV silicone rubbers are now powered by the TOMPS Viscolo Addition Cure Range. Although this rubber appears un-branded, it is in fact manufactured by one of the world's leading RTV Formulators and Manufacturers.

This RTV has fantastic elongation to break and tear resistance. Its incredibly low viscosity allows efficient home production casts in rigid moulds or add cure silicone moulds with release agents.

We supply our Coloured RTV as a clear with seperate pigment. This is due to an automatic thixotroping effect caused by the pigment. Simply add the pigment to your mixes as you make them @ up to 10%. Some colours need more than others to provide opacity. At less than 1% you wil find quite a translucent mix can be achieved. We now offer other colours. See the option list.

We include 50g pigment for the 500g kit and 50g pigment per 500g of base rubber total.

Please see our main items of Addition cure 13, 33, 45A for datasheets however the MSDS is a family datasheet covering all shores.
