Wont silicone become brittle with high temperatures? This will be exposed to the high temperature multiple times and needs to remain flexible for thermal expansion.
I am looking for a sealant that fits the following requirements:
- Withstand 1400 F for 10 seconds
- Withstand 400 F for 90 min
- Flexible (due to thermal expansion), watertight
- Must fill ¼” gap
- Adhere to steel
- Exposed to weather (UV degradation, rain/sea water, fuel/oil)
Is there...
