The intent of the experiment was to find a cleaning solution that could remove the adhesive bond between the two substrates.
Two solutions were selected from the Laboratory’s database based on substrate compatibility and the cleaner's ability to remove adhesives. Full strength solutions were used in a beaker. The solutions were heated to 130 F and placed into a Crest 40 kHz ultrasonic tank. The sample was placed into the cleaning solutions and observed every five minutes up. After each interval, the sample’s position in the beaker was changed to aid the ultrasonic cleaning. At the end of 15 minutes, the part was removed from the cleaning solution and rinsed in tap water at 120 F for 30 seconds. The part was dried using air blow off and a Master Heat Gun Model HG 301A with a temp range of 300-500 F for 30 seconds. The part was observed to determine if separation was achieved.
