Laboratory evaluations of alternative cleaning products
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
One product was heated to 130 F on a hot plate and two products were used at full strength. Twenty-four preweighed coupons were coated with Ashland Acrylic Resin Aroset 1872 Z40 (108-88-3, 141-78-6, 142-82-5, 67-63-0) and allowed to dry for a half an hour and reweighed. Three coupons were cleaned in each solution for 5 minutes using stir-bar-agitation, rinsed in a tap water bath for 15 seconds at 120 F and dried using air blow off for 30 seconds at 68 F. Coupons were allowed to dry for a half an hour and then reweighed a final time. Efficiencies were calculated.
Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
None of the products were effective at removing the contaminants.
