The US Army Research Laboratory was tasked with evaluating hazardous air pollutant HAPfree alternative paint strippers for validation to Federal Specification TT-R-2918A. One of the major obstacles in finding suitable drop-in replacements for methylene chloride is that most HAP-free products have been known to have slower paint removal times. Strip time and performance are important considerations in high-volume operations. The results presented in this report represent the performance of the HAP-free strippers versus a control formula remover in accordance with procedures outlined in Federal Specification TT-R-2918A on both Navy and Army coating systems. The results indicate that some of the alternative strippers performed well compared with the control and the methylene-chloride-based product. One product had performance comparable to that of methylene chloride, removing nearly 100 of all paint layers from the test panels. Depending on the stripping application and coating systems, some of the products tested are considered viable alternatives to methylene chloride strippers.
