Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
03/22/2002Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Cleaning: 5 min. immersion cleaning at 120 F with stir bar agitation. (all the organic cleaners were run at room temperature)
Oil - Winfield Brooks Alumtap (64742-53-6, 127-18-6, 111-63-7)
Trial Results:
Observations: The coupons cleaned with perfluorosolve PFS 1 had cleaner on them even after rinsing. This cleaner was used by spraying as there was not enough cleaner to immerse the coupons completely.
The cleaner Westech CT-4721 reacted with aluminum coupons violently and hence were removed after 30 sec.
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
