CHEMICAL RESISTANCE
White printable zone of B-427 was printed with Brady Series R4300 black thermal transfer ribbon. Samples wrapped around
0.080” OD TFE wire in a self-laminating format. Except where noted, testing was conducted at room temperature after 24
hour dwell. Testing consisted of 5 cycles of a 10 minute immersion in the specified test fluid followed by a 30 minute recovery
period.
