Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.
Special features
very good flow
fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
low Shore A hardness (approx. 28)
high tear strength
excellent long-term stability of the mechanical properties of the vulcanizate
outstanding resistance to concrete
Application
Due to its outstanding resistance to concrete and superior mechanical properties, ELASTOSIL® M 4630 A/B is ideal for use in molds for making concrete reproductions of models with deep undercuts. As a low-Shore, addition-curing RTV-2 silicone rubber, which cures without dimensional shrinkage, ELASTOSIL® M 4630 A/B is also extremely suitable for casting all other common reproduction materials, especially casting resins where absolutely accurate copies of models with pronounced undercuts are required.
