Trial Number 1

Trial Purpose:

To evaluate client supplied cleaning solution on all listed contaminants and one substrate.

Date Run:

08/12/1999

Experiment Procedure:

The cleaning solution was used at full strength in a 600 mL beaker. The solution was heated to 130oF. Coupons were cleaned for five minutes. Rinsing was performed for two minutes using tap water at 120oF and air dried for about two hours also at room temperature. After drying is complete, final weights are recorded and efficiencies are calculated.

SUBSTRATE MATERIAL: Stainless Steel (202-316B-80)
CONTAMINANTS: Table 1 lists the contaminants and the related CAS#s for this trial.
Table 1. Contaminants Cleaned
Contaminant CAS #
Oil 64741-89-5
Ink 67-63-0, 108-88-3, 9004-70-0, 141-78-6, 64-17-5, 109-60-4
Adhesive 9010-98-4, 65997-13-9, 68083-03-4, 67-56-1, 1314-13-2, 119-47-1, 108-88-3, 8052-10-6

Trial Results:

The Engine Degreaser was very successful in removing the adhesive and the oil from the stainless steel coupons. It was ineffective on the ink. Table 2 lists the calculated efficiencies.

Oil 99

Success Rating:

A follow up test, usually based on company input.

Conclusion:

The Engine Degreaser proved very effective on the oil and moderately successful on the adhesive tested.  Further evaluation on other contaminants will take place.
