Trial Purpose:

Determining HSP Sphere coordinates for Flexcon's 1304 acrylic adhesive

Date Run:

11/12/2025

Experiment Procedure:

24 scintillation vials were filled with 24 different solvents from TURI's HSP matrix. The 1304 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 adhesive 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.

14 – Diethyl Carbonate 0
15 – 1-propanol 0
16 – Isopropanol 0
17- Propylene Carbonate 0
18 – Thiophene 1
19 – 1-Methoxy-2-Propanol 0
20 – Dimethyl Sulfoxide 0
21 – 1-Butanol 0
22 – Dimethyl glutarate 1
23 – Anisole 1
24 – 2-Butoxyethyl-Acetate 0

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

Of the 24 solvents tested, Benzyl Alcohol, Ethyl Acetate, Thiophene, Dimethyl Glutarate, and Anisole succeeded in successfully dissolving the soil. The other 19 solvents did not succeed in dissolving the soil
