Determining the HSP sphere for Flexcon's 7244 Solvent Acrylic Adhesive
Date Run:
10/29/2025
Experiment Procedure:
24 scintillation vials were filled with 24 different solvents from TURI's HSP matrix. The 7244 Solvent Acrylic Adhesive was spread onto wax paper and allowed to air dry for 3-4 hours. After it was dry, but not hardened, balls of topcoat were scraped into each of the 24 scintillation vials and allowed to soak. For the first hour, visual observations were taken every 10 minutes, then following the first hour observations were taken every half hour up until 3 hours. The vials were then allowed to sit overnight before final observations were taken.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
Based on the results of this test, Dimethyl Carbonate, Benzyl Alcohol, Methyl Acetate, Ethyl Lactate, Acetone, Ethyl Acetate, Ethanol, 1,3-Dioxolane, Diethyl Carbonate, 1-propanol, isopropanol, 1-methoxy-2-propanol, 1-butanol, dimethyl glutarate, anisole, and 2-butoxyethyl-acetate. The other 8 solvents were not successful in dissolving the soil.
