Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
01/31/2002Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Cleaning: Manually hand wiped coupons at ~ room temp of 68 F with paper towel, 3-4 times
Rinsing: 1/2 min, manual, with tap water @ 120 F
Drying: 1 min with heat gun at 500F
Contaminant: Aroset PS 8078, Ashlan Chemical (Lot# 071901). Very thick adhesive
Trial Results:
VG 151 Very effective. Gel consistency. Dissolved adhesive well.
RST 5 Removed a good portion of the adhesive but it would have taken considerable manual work to remove the rest or another application to finish the removal.
1050 Magic removed some of adhesive. Would require considerable manual labor to remove the rest of the adhesive or another application of the cleaner with a longer soaking time.
Westech CT 1550 Same is for RST 5 & 1050 Magic
Fingerlakes Chemicals Same as previous 3 cleaners
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
VG-151 was very effective. Used 5 cleaners that specifically stated they would work on adhesives and resins. The coupons used were from trial 159, 161 & 165 that were not able to be cleaned by immersion, ultrasonics or media blasting.
