Processing
The platinum catalyst is contained in component B.
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.
Pigmentation
If so desired, 1-4 wt % ELASTOSIL® Pigment Pastes FL can be added, preferably to Component A.

- Properties
- Easy to process because of low viscosity
- Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat.
- Cures in closed systems
- Low Shore A hardness
- High elongation, outstanding tensile strength
- Excellent tear strength
- Cured rubber is translucent and colorless.
- Can be pigmented with 1-4 % ELASTOSIL® Pigment Pastes FL.
- Note
Compression molded 10 min at 100 °C for cured properties.

Safety & Health
- Safety Note
Components A and B of the addition-curing grade ELASTOSIL® RT 625 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.
