Trial Report



Trial Number 4

(Client Number 220, Project Number 1)

Trial Purpose: To evaluate five new products on the first supplied soil.

Date Run: 04/30/04

Experiment Procedure:
Five products were selected based on client request for vapor degreasing solvents. Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate.
Fifteen preweighed aluminum coupons were coated with the Soltex Polybutene 32 (9003-29-6) using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were weighed a final time and efficiencies were calculated.

Trial Results
All five products removed over 90% of the contaminant within five minutes.  The table lists the amount of soil added, the amount remaining and the
efficiency for each coupon cleaned.
