YJS-630 addition cure rtv2 mold making liquid silicone for artificial stone casting

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 stability 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.
