Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.
Special features
good flow
fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
high Shore A hardness (approx. 55)
high tear strength
long-term stability of the vulcanizate’s mechanical properties
outstanding resistance to common casting resins
Application
Due to its outstanding resistance to casting resins as well as its superior mechanical properties ELASTOSIL® M 4670 A/B is perfectly suitable for all molds of models with undercuts that are to be reproduced in casting resins, and a certain inherent rigidity of the molds is required. As a medium-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4670 A/B is also extremely suitable for casting all other common reproduction materials, particularly if absolutely accurate copies of models with undercuts are required.
