- Application Details
- Important :
- The platinum catalyst is contained in component A. 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 C 670 A/B. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compoundsespecially organo-tin compounds.
- If a substrate’s ability to inhibit curing is unknown, a small scale test should be run to determine compatibility.
- Mixing :
- Components A and B must be homogenized before use, due to separation of light weight filler. 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.
- 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”.
- Curing :
- Curing time of addition curing silicone rubber is highly dependent on temperature, size and heat sink properties of the component being potted.
