Appendix C. Sensor material
properties
The sensor consists of 6061 aluminum (hard anodized), RTD, 3M F9473PC adhesive, and
Santoprene® jacketed cable.
C.1 3M F9473PC adhesive
UV resistance: Excellent UV resistance through outdoor weathering tests.
Temperature resistance: Relatively unaffected by long-term exposure to elevated temperatures.
Adhesive can tolerate periodic short-term exposures to temperatures up to 260 °C. The adhesive
softens as temperature increases and gets firmer as temperature decreases. As the adhesive
becomes firmer, the bond strength generally increases. However, at very low temperatures
(<-40 °C), the bond strength decreases.
Solvent resistance: No apparent degradation when exposed to splash testing of many common
solvents and fluids including gasoline, JP-4 fuel, mineral spirits, motor oil, ammonia cleaner,
acetone and methyl ethyl ketone. Three-splash testing cycles were 20 seconds submersion and 20
seconds air dry.
Storage and shelf life: Humidity controlled storage: 16 to 27 °C (60 to 80 °F) and 40 to 60%
relative humidity. If stored properly, product retains its performance and properties for 24 months
from date of manufacture. If the products have been exposed to severe weather conditions, we
suggest to precondition the products at the above storage conditions for at least 24 hours before
using them.
