T20 by Neill’s Materials is a translucent silicone elastomer which cures at room temperature by a polyaddition reaction. This is a two component, 1:1 mix ratio silicone. T20 is one of the lowest viscosity silicone on the market.
It is super fast curing and can be demoulded in 10-15 minutes. T20 exhibits extremely high strength and is fantastic for quick mould making. If 10 minutes is too quick for your application, you can slow with Retarder.
