∗ Brady Corporation Lab Test Procedure
Performance properties tested on B-508 white and yellow printed with the Brady Series R5000 dot matrix ribbon and with the
Brady Series R4300 thermal transfer ribbon. B-508 white samples were also laser marked with a 10 watt fiber laser. Unless
noted, results are the same for both colors of topcoat and all printing processes and ribbons.

PERFORMANCE PROPERTY
CHEMICAL RESISTANCE
B-508 white and yellow samples printed with the Brady Series R5000 dot matrix ribbon and with the Brady Series R4300 thermal
transfer ribbon. B-508 white samples were also laser marked with a 10 watt fiber laser. Samples were dwelled a minimum of 24
hours before testing. Test conducted at room temperature. Testing consisted of 30 minute fluid immersion. After immersion, the
printed image was rubbed on 10 times with a cotton swab saturated with the test fluid. The rating scale below shows the effect to
the quality of the print and topcoat, if applicable, for each sample. Unless noted, results are the same for the white and yellow
topcoats.
