* Brady Corporation Lab Test Procedure

Performance properties tested on B-508 printed with Series R2000 and R5000 dot matrix ribbons and with Series R4300 and Brady 356126 thermal transfer ribbons. B-508 printed samples were tested on  white,  yellow  and green topcoats. Unless noted, results are the same for all colors of topcoat and all ribbons.

PERFORMANCE PROPERTY
CHEMICAL RESISTANCE

B-508 samples printed with Series R5000 and R2000 dot matrix ribbons and with Series R4300 and Brady 356126 thermal transfer ribbons.  Samples dwelled a minimum of 24 hours before testing.  Test conducted at room temperature on  B-508 white, yellow and green. 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,  yellow and green  topcoats.
