Processing
- Important
- The platinum catalyst is contained in component B. 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 POWERSIL® GEL A/B. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds - especially organo-tin compounds.
- If a substrate’s ability to inhibit curing is unknown, a small scale test should be run to determine compatibility.
- Mixing :
- The two components should be thoroughly mixed at a 1 : 1 ratio by weight or volume. To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended.
- 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 of the gel with corresponding reduction or pot life and curing time. Further information is given in our leaflet “Catalyst EP/Inhibitor PT 88”. If the gel is too soft and tacky, reducing the amount of component B will result in a harder, less tacky vulcanizate.
- The hardest formulation is achieved with a mixing ratio for A : B of roughly 1.5 : 1. We recommend running preliminary tests to optimize conditions for the particular application.
- Comprehensive processing instructions are given in our leaflet “Wacker RTV-2 Silicone Rubber-Processing”.
- Curing :
- Curing time of addition curing silicone rubber is highly dependent on temperature, size and heat sink properties of the component being potted.
