CS25 Condensation Cure Rtv Silicone Rubber is a low viscosity, two-part condensation cure silicone rubber. It is used for silicone mould making where it is mixed (with its catalyst) and then poured around a pattern to create a flexible silicone mould.
CS25 has been specially selected for its ease of use, excellent performance and great value.
Once cured the silicone rubber is very soft and flexible making it perfect for casting complicated or intricate shapes where the cast part can be easily removed from the silicone mould. The long pot-life of our silicone allows plenty of time for careful pouring and self de-gassing although forced degassing in a vacuum chamber can also be performed if required.
Easy to use - no special equipment or conditions required
High tear strength and excellent elongation (making removal of even complex shapes from the mould easy)
Good chemical resistance to styrene and polyurethane
Low viscosity - fantastic flow properties
This kit comes with a 476 gram tub of silicone and a 24 gram catalyst.
