The stripping effectiveness of Fine Organics FO606 and Turco 5668 have been evaluated and compared to Oakite Stripper SA. Testing was carried out in the Chemical Cleaning Facility, FMF Capte Scott on pipe sections and elbows coated with a white powder epoxy coating as well as pipe brackets and valve covers coated with a black spray epoxy coating. All paint strippers were used in accordance with the manufacturers recommended procedures. The results indicate that Fine Organics FO606 removed 100% of the white powder epoxy coating after 4 hours and 90% of the black spray epoxy coating after 6 hours. This result was similar to the methylene chloride based stripper that removed 100% of the white powder epoxy after 2 hours and 100% of the black spray epoxy after 6 hours. However, Turco 5668 removed 95% of the white powder epoxy after 6 hours but less than 5% of the black spray epoxy after 24 hours. Monitoring of Volatile Organic Compounds (VOCs) indicated that there were no serious health concerns with the use of N-methylpyrrolidone (NMP)/ethanolamine based solvents in properly ventilated cleaning facilities. A cost analysis indicated that Fine Organics FO606 was almost twice as expensive as Oakite Stripper SA (-$12.50 CND/L versus -$7.00 CND/L). The cost of Turco 5668, which was ineffective as a stripper for the black spray epoxy coating, was $13.30 CND/L.
