Appendix A. Probe Material Properties
The probe consists of 6061 aluminum (clear anodized), thermistor, 3M9485PC
adhesive, and Santoprene jacketed cable.
A.1 3M 9485PC Adhesive
Humidity Resistance: High humidity has a minimal effect on adhesive
performance. Bond strengths are generally higher after exposure for 7 days at 90°F
(32°C) and 90% relative humidity.
U.V. Resistance: When properly applied, nameplates and decorative trim parts are
not adversely affected by outdoor exposure.
Water Resistance: Immersion in water has no appreciable effect on the bond
strength. After 100 hours in room temperature water the bond actually shows an
increase in strength.
Temperature Cycling Resistance: Bond strength generally increases after cycling
four times through:
• 4 hours at 158°F (70°C)
• 4 hours at -20°F (-29°C)
• 16 hours at room temperature
Chemical Resistance: When properly applied, adhesive will hold securely after
exposure to numerous chemicals including gasoline, oil, Freon™ TF, sodium
chloride solution, mild acids and alkalis.
Heat Resistance: Adhesive 350 is usable for short periods (minutes, hours) at
temperatures up to 350°F (177°C) and for intermittent longer periods (days, weeks)
up to 250°F (121°C).
Low Temperature Service: -40°F (-40°C). Parts should be tested for low
temperature shock service.
