- Applications
- Reproduction Molding for Foundry, Arts and Handicrafts.
- Making shrink-free molds with excellent reproduction accuracy.
- Application Details
- 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.
Processing
Important note:
- The platinum catalyst is in component B.
- A and B components may only be used together if they have the same batch number.

Safety & Health
- Safety Note
Components A and B of the addition-curing grade ELASTOSIL® M 4600 A/B contain only constituents that over many years have proved to be neither toxic nor aggressive. Special handling precautions are therefore not required, i.e., only the general industrial hygiene regulations apply.
