- Application Details
- 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 FC 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 RubberProcessing”
- Pigmentation:
- POWERSIL® GEL FC A/B can be pigmented by adding 1 - 4 % of an ELASTOSIL® FL pigment paste.
- Curing:
- Curing time of addition curing silicone rubber is highly dependent on temperature, size and heat sink properties of the component being potted.
