To identify a suitable, non- or less-toxic substitute cleaner for toluene and toluene-based solvents for this industry sector.
In an effort to obtain consistent results, this experiment is a re-test of Trial 5. The test is identical to Trial 5, with a notable modification: following the abrasion testing, and final coupon weighing, the coupons were hand-wiped clean using the corresponding cleaner that was used in the abrasion test. Hand-wiping was timed to obtain a quantitative means of analysis.
SUBSTRATE MATERIAL: SS (202-410 B85) and SS (302-B86)
a. AC-059 adhesive (108-883),
b. Morton 717 adhesive (108-883, 108-05-4, 110-54-3, 142-82-5, 67-63-0)
There were very few consistent findings in this experiment. For instance, the Dynamold DS 104 cleaner performed almost identically on both adhesives, about 65%. But acted very differently on each substrate during the hand wipe test. It took less than one minute to clean one adhesive but took over 3 minutes for the other adhesive.
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
It is important to note the poor performance of D-Greeze on Solutial, where as it cleaned 20% in trial 6. Toluene worked the best.
