PERFORMANCE PROPERTY
CHEMICAL RESISTANCE

Chemical resistance tested on B-425 printed with Series R4300, R6200 and R6400 ribbons on a BradyPrinter™ THT 300 MVP thermal transfer printer. Test was conducted at room temperature except where noted. Testing consisted of 30 minute immersion in the specified test fluid. The samples were removed and rubbed 10 times with a cotton swab saturated with the test fluid. The rating scale below shows the effect to the quality of the print for each sample.
