To evaluate successful products under conditions closely matching current practice at client facility.
Four products selected from previous testing. The products were used at full strength. Products were used at room temperature. Twelve preweighed coupons were first coated with Valspar MR 225 mold release (100-41-4, 1330-20-7, 8052-41-3, 67-63-0, 108-88-3, 110-82-7, 64742-89-8), followed by a second coating with Valspar MR 225 Aerosol (75-28-5, 74-98-6, 100-41-4, 75-09-2). The coupons were placed into a convection oven at 150 F and allowed to cure overnight. After the coupons were cooled to room temperature, a thin strip of Chockfast Orange Resin was applied and allowed to dry. A second set of weights were recorded to determine the amount of contaminant that was added.
Three coupons were cleaned in each product for five minutes using stir-bar agitation. After cleaning the coupons were removed and dried using compressed air at room temperature. Final weights were to be recorded after coupons were dry. Observations were made and recorded.
No products were effective. The products may have removed some mold release but no resin which was really the issue.
