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. A "0" denotes that less than 80% of the target soil was dissolved. While a rating of  "1" denotes greater than 80% dissolution of the target soil.
