Trial Number 2

(Client Number 41, Project Number 1)

Trial Purpose: Additional cleaners to remove adhesive

Date Run: 03/23/98

Experiment Procedure:
The purpose of this experiment was to find additional cleaners that could be used to remove the adhesive from the plastic laminate. Several chemistries were selected from the laboratory?s database of in-house cleaners. The cleaners were selected on one of two categories: substrate compatibility and contaminant removal. A paper towel was saturated with a cleaner at full strength. The towel was applied to the coupon in a circular motion with minimal pressure for about a minute. The effectiveness of the chemist was determined visually.
SUBSTRATE MATERIAL: Plastic coupons (2" x 4")
CONTAMINANTS: 3M contact cement--30NF

Trial Results
Of the fourteen chemistries tested, only four showed signs of removing the adhesive from the surface.  These chemistries were: Fisan Versaclean,
Safety Prep, D-Greeze 500, and  Bio-T MAX.  Since only one of the four cleaners came from the substrate compatibility category, an additional test
will be performed to determine if there will be any problems with the cleaners and the plastic substrate.


Success Rating
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion
Four cleaners were shown to be effective in removing the adhesive from the plastic surface. Three of the chemistries will undergo a compatibility study. All four will then be tested quantitatively for removal of the adhesive.
