Laboratory evaluations of alternative cleaning products
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Two hundred fifty milliliters of each product wereused at full strength in a 4000 ml beaker and heated to its boiling point on a hot plate. Preweighed aluminum coupons were coated with the Soltex Polybutene 32 (9003-29-6) using a handheld 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 vapor degreasing. After cooling to room temperature, the coupons were weighed a final time and efficiencies were calculated.
|Cleaner||Initial wt||Final wt||% Removed|
Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Eleven of the fourteen products removed over 85%
