Freezerbondz printable labels for thermal transfer printers. These labels are on a 1" core, a smaller core than the majority of our materials. The recommended printer for these small core parts is the BBP11-34L printer. B-492 offers excellent print smudge resistance, solvent resistance when using the R6400 Riboon, and excellentlow temperature performance. B-492 performs well in common laboratory environments such as liquid nitrogen and autoclave applications. We recommend Brady R6400 ribbons with Brady series R4300 as an inferior but acceptable alternative. Note: R4300 ribbon may be used if chemical resistance is not required with Ethanol, Toluene and Xylene.
