- Application Details
- Due to the outstanding resistance to casting resins as well as the superior mechanical properties, ELASTOSIL M 4601 A/B is especially suitable for all molds of models with extensive undercuts that are to be reproduced in casting resins.
- As a low-Shore addition-curing RTV-2 silicone rubber that cures without undergoing dimensional shrinkage, ELASTOSIL® M 4601 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
- The platinum catalyst is in component B.
- A and B components may only be used together if they have the same batch number.
- Applications
- Making shrink-free molds with excellent reproduction accuracy.
- Automotive molding
- Reproduction Molding

- Properties
- Very good flow
- Low viscosity
- Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat.
- Low Shore A hardness (approx. 28)
- High tear strength
- Excellent long-term stability of the mechanical properties of the cured rubber.
- Outstanding resistance to common casting resins particularly polyurethane.
- Note
Cured properties are vulcanized after 24 h at 23 °C.
