SC-454M-6 is designed for potting and encapsulation of electrical/electronics components that require the dissipation of heat and the high temperature properties and low stress of a silicone compound. The cured material may be knife-cut for replacement of components and new compound may be poured in place and cured to re-form tight seal. Thermally conductive silicone potting compound used to encapsulate power supplies and heat sinks for LED lighting.
Applications & Uses
- Applications
- Cure Method
- Instruction for Use
Some filler settlement may occur during shipping and storage. Mix well the contents every time before removing material.
- To use, mix, at room temperature, 100 grams of SC- 454M-6 (A) with 3 to 5 grams of SC-454M-6 (B).
- Mix well until uniform in consistency and vacuum degasses.
- Cure as recommended achieving the desired properties.
- Typical cured properties were determined using recommended cure schedule. Some difference in properties may occur with other cure schedules.
