Trial Report



Trial Number 1

(Client Number 41, Project Number 1)

Trial Purpose: Acetone baseline to compare alternatives

Date Run: 08/11/97

Experiment Procedure:
Seven chemistries were selected for testing. In addition to the chemistries, Acetone was used to give a baseline level to compare the alternatives to. The chemistries selected were:
Company Tradename Concentration
Brulin & Company Compliance 50%
AW Chesterton 803 100%, 50%
MacDermid ND-17 50%
Isopropyl Alcohol ISP 100%
Polychem P.X.P. 100%
Easter Color Eccobrite Cleaner AK 100%
Tarksol Corp HTF 85B 100%

The cleaners were applied to the sample using a saturated paper towel. The time and effort required to clean the contaminant were observed and noted. These two factors were then used to construct a table of cleaning effectiveness.
SUBSTRATE MATERIAL: Plastic
CONTAMINANTS: 3M contact cement--30NF

From the results obtained in the previous trial and from this trial, there were five possible alternatives for acetone.  These cleaners were:  Loctite
7360, Brulin Compliance 100%, Terpene Technology HTF 85B, Eastern Color & Chemical Company Eccobrite Cleaner AK and Isopropyl Alcohol.  A table with
more information on each cleaner was constructed to aid in the selection process.

It should also be noted that Isopropyl alcohol is flammable.  In using IPA as a replacement, the current hazard may be eliminated; However, a
different hazard comes into existence.


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

Conclusion
After trying several chemicals, five cleaners showed excellent removal of the contaminant. Additional information on these chemistries were provided to help aid the client in the selection of an appropriate substitution for Acetone.
