Project Number 1
Test Objective:
Identify alternative to TCE to remove water-based rosin from lead and equipment surfaces.| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 06/18/2020 | To test the effectiveness of aqueous and solvent based cleaners in removing water-based rosin from stainless steel coupons. | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 1 | 07/08/2020 | The purpose of this experiment was to determine the effectiveness of four cleaners; Propylene carbonate, SC Aircraft & Metal Cleaner, Ozzy Juice SW-3 and Dimethyl glutarate in removing a water rosin based coating from glass coupons using heated immersion at 120F for 15 minutes. | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 2 | 07/10/2020 | The purpose of this experiment was to determine the effectiveness of five cleaners; Isopropyl alcohol, SC Aircraft & Metal Cleaner, Dimethyl glutarate, Propylene carbonate, and RB Degreaser, in removing a water based rosin from stainless steel substrates with unheated manual wiping. | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
