Trial Purpose:
The purpose of this experiment was to repeat 30 minute heated immersion with a stir bar using Mirachem 500 as requested by the company.
Date Run:
10/06/2020Experiment Procedure:
A solution of Mirachem 500 was prepared to a concentration of 25% and heated to 140°F. Two glass coupons were obtained and weighed. One coupon was then soiled with Rosin #2 while the other was soiled with protect-o-coat and dirty weights were recorded. Once the cleaning solution reached the proper temperature, the coupons were submerged into the beaker along with a stir bar for agitation for 30 minutes. Once 30 minutes had passed, coupons air dried for 24 hours, and a clean weight was then recorded. Effectiveness of the cleaner was then determined.
Trial Results:
| Cleaner | Soil | Initial wt of cont | Final wt of Cont | %Cont Removed |
| Mirachem 500 | Rosin #2 | 0.1247 | 0.1025 | 17.80 |
| Protect-o-coat | 0.0029 | 0.0007 | 75.86 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Mirachem 500 removed 17.80% of Rosin #2 and 75.86% of protect-o-coat from glass coupons via heated immersion with agitation.
