Trial Report

Trial Number 144

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 01/15/02

Experiment Procedure:
Cleaning: 5 min Immersion cleaning with stirbar agitation @ 120 F
Rinsing: 1/2 min, manual, in 102 F water (tap)
Drying : 1 min with heatgun @ 500F
Contaminant: ITW, Dykem Corp, Ink, Steel Blue - DX - 100
CAS#'s 64175, 12386

Trial Results
None of these cleaners were effective on the dried ink contaminant. The LF 2100 was especially uneffective, it seemes to react with the ink and
deposit an oily or greasy substance onto the coupon, increasing its weight dramatically. LF:  This cleaner reacted w/ the ink, changing its color from
deep blue-green to purple greasy/oily film. After cleaning the ink never dried, it stayed tacky or wet.  Gravimetric analysis showed there was a
significant increase in weight.

Success Rating
Lab evaluation based on vendor data.
