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. 20)
good transparency
high tear strength
excellent long-term stability of the mechanical properties of the cured rubber
outstanding resistance to common casting resins
Application
Due to the outstanding resistance to casting resins as well as the superior mechanical properties, ELASTOSIL® M 4600 A/B is especially suitable for all molds of models with extensive undercuts that are to be reproduced in casting resins. In addition to the low hardness, which facilitates demolding, ELASTOSIL® M 4600 A/B has the advantage of being transparent. This makes it possible to cut onepart molds under visual control along a parting line which has been established before or is determined by the shape of the model, a method which often saves making a two- or multi-part mold. As a low-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4600 A/B is also extremely suitable for casting all other common reproduction materials, particularly if absolutely accurate copies of models with pronounced undercuts are required.
