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.
