ELASTOSIL® M 4600 A/B
Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.
Main application: Making shrink-free molds with excellent reproduction accuracy, food contact (FDA/ BfR compliant).
- 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
ELASTOSIL® M 4600 A/B的特殊性能
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
The platinum catalyst is in component B.
A and B components may only be used together if they have the same batch number.

The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
