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.
