Chemical resistance

Samples were thermal transfer printed with Brady Series R-6000 black ribbon and R-4400 white ribbon on the Bradyprinter^TM BP-THT-Precision 300dpi printer.
Testing consisted of 5 cycles of 10 minute immersions in the specified chemical reagent followed by 30 minute recovery periods.
After the final immersion, the samples were removed from the test fluid and the printed image rubbed 10 times with a cotton swab saturated with the test fluid.
