HSPiP

A bead of jowatherm 288.60 hot-melt adhesive were placed in 24 individual scintillation vials. These vials were
then placed on rollers and monitored for 3 hours. Ever hour visual observations were taken to examine
whether or not the adhesive was being dissolved. A "1" rating is for soil that is mostly (greater than 80%)
or completely dissolved. While a "0" rating is for soil that is not dissolved or somewhat (less than 80%)
dissolved.

None of the selected solvents were able to mostly or completely dissolve the adhesive. Given the goals of the cleaning procedure utilized by conklin, an adjustment of experimental goals is necessary.
