Breif description
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.30).
- high tear strength
- excellent long-term tability of the mechanical
properties of the vulcanizate
- outstanding resistance to concrete
Application:
Due to its outstanding resistance to concrete and superior mechanical properties, YJS-630 A/B is ideal for use in molds for makingconcrete reproductions of models with deep undercuts.
As a low-Shore, addition-curing RTV-2 silicone rubber, which cures without dimensional shrinkage, YJS-630 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.
