Date Run:

03/12/2002

Experiment Procedure:

Cleaning: 5 min. immersion cleaning at 120 F with stirbar agitation.
Rinsing : 1/2 min. manual with water at 120 F
Drying : 1 min. with heat gun at 500 F.
Contaminant: gelva multipolymer resin solution.
Cas #: 50862-46-9, 141-78-6, 142-82-5, 67-63-0, 64-17-5, 108-05-4.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

None of the cleaners worked. Tarksol HTF- 60 was tested again as it left the resin solution dry even after rinsing. The coupons were soaked in the cleaner for 1 hr. and eft hanging for 2 days. Almost all the resin dripped off the coupons.
