Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature.
Properties
- Medium Shore A hardness (approx. 43)
- Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
- Very good flow properties
- Good transparency of the cured rubber
- High tear strength
- Outstanding resistance to casting resins, particularly polyurethanes and epoxies, for long service life of the molds
Data sheets
High-performance silicone mold-making compound which is particularly suitable for reproducing models with undercuts in polyurethane or epoxy resins.
Main field of application: Vacuum casting for rapid prototyping especially suitable if crystal-clear casting resins are used.
Important
The platinum catalyst is contained in component A.
Caution
Only components A and B that have 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 to the right 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 150,000 mPa s.
The curing times apply to a layer thickness of 1 cm.
Storage
The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis 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.
