Processing
Caution:
Only components A and B with the same lot number may be processed together.
Surface preparation:
All surfaces must be clean and free of contaminants that will inhibit the cure of ELASTOSIL® RT 601 A/B. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds - especially organotin compounds. If a substrate's ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.
Mixing:
- Component A of ELASTOSIL® RT 601 contains the platinum catalyst, component B the crosslinker. Even traces of the platinum catalyst may cause gelling of the component containing the crosslinker.
- Therefore tools (spatula, stirrers, etc.) used for handling the platinum containing component or the catalyzed compound must not come into contact with this component.
- The two components should be thoroughly mixed at a 9 : 1 ratio by weight or volume. To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.
Curing:
- Curing time of addition curing silicone rubber is highly dependent on temperature, size and heat sink properties of the component being potted.
- The reactivity can be adjusted within wide limits by adding Catalyst EP or Inhibitor PT 88 to suit the processing requirements of the particular application. Catalyst EP increases the reactivity, i.e., pot life and curing time are reduced. Inhibitor PT 88 is a pot life extender and prolongs pot life and curing time.
