ELASTOSIL® M 4130 US A/B
Pourable, addition-curing, 1:1 two-component silicone rubber that vulcanizes at room temperature.
- Very good flow
- Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
- Medium hardness (Shore A approx. 30)
- High tear strength with unique knotty tear characteristics
- Excellent long-term stability of the mechanical properties of the vulcanizate
- Great resistance to common casting resins
Due to the outstanding resistance to casting resins as well as the superior mechanical properties, ELASTOSIL® M 4130 US 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 medium hardness, which facilitates demolding,ELASTOSIL® M 4130 US A/B has the advantages of low viscosity, knotty tear, and relatively high specific gravity, making it an advanced molding compound suitable to many applications. As a medium-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4130 US 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.
The platinum catalyst is contained in component A.
Only components A and B with the same lot number may be processed together!
To ensure optimum flow of the material, the components must be stirred thoroughly before they are removed or processed in their containers.
The tables below indicate the pot lives and curing times at various temperatures.
The pot life figures indicate the time required for the mix to reach a viscosity of 60 000 mPa s.
The curing times apply to a layer thickness of 0.40”.
