Trial Purpose:
To screen potential cleaning products for removing paint/resin from steel parts
Date Run:
10/19/2007Experiment Procedure:
Six products from the previous trial were identified for further testing. While all 14 previous products showed potential, products were picked for more extensive testing based on performance, EH&S and possible cost considerations. 100 milliliters of each product at 100% solution were placed in a 200 ml beaker, except Micro 90, a 10 and 20 % solution were used. A small piece of cured paint/resin taken from a supplied bucket of resin and was placed in the beaker.
The paint/resin was allowed to sit in the solution to determine what effect the cleaning products would have. Observations were made at 30, 60, 120 and 180 minute intervals as well as overnight. Any signs of interaction between paint/resin and cleaner were recorded.
Trial Results:

| 120 min | No change |
| 180 min | Resin slightly softened |
| Overnight | Solution still clear. Resin was brittle and broke easily |
Success Rating:
A follow up test, usually based on company input.Conclusion:
Again, all products showed some promise, but the Rochester Midland and Spartan products showed the most and are some of the top choices in the EH&S and economic categories. These two will be tested further in heated immersion and ultrasonics testing to find the optimum time for cleaning and under what conditions.
