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.
