Trial #1
To evaluate one cleaner and hot water for coating removal
Two parts were to be cleaned using hot tap water and Fine Organics Resineater. Both were heated to 150 F on a hot plate at full strength in a 250 mL beaker. One part was placed in each solution. The part in the water was allowed to soak for 5 minutes. At the end of the soaking, the coating was removed by peeling. The part placed in the Resineater solution was allowed to soak for 30 minutes. After soaking the part was removed and observed for signs of the coating.
SUBSTRATE MATERIAL: Nickel parts
CONTAMINANTS: Coating-Styrene Butidiene
Most of the coating was removed after peeling. Peeling took about 5-7 minutes. Small amounts of the contaminant did remain. The Resineater-soaked part was not as successful in the removal of the coating. The remaining coating appeared to be very soft.
The water-soaked part had most of the coating removed within several minutes, whereas the Resineater-cleaned part still remained partly coated. The one problem that may arise in using the water and peel method would be in the hands-on effort required to remove the coating. Also, there were trace amounts of the coating which could not be easily peeled. This residual coating could be soaked in the Resineater solution. The small portion of the contaminant would dissolve with little extra time.
