Trial Number 235

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:

04/10/2003

Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

Cleaning: 5 min Immersion cleaning with stir-bar agitation @ 120 F
Rinsing: 1/2 min, manual, in 102 F water (tap)
Drying: 1 min with heat gun @ 500F
Contaminant: Cerdec magenta Ink CAS# 119-64-2, 65997-18-4, 1345-24-0, 20667-12-3

Success Rating:

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

Conclusion:

Many coupons look as if they would be significantly cleaned with just wipe. The ink has been softened, lifted or dissolved to enhance removal. See trial 236A for follow-up.
