TDS - BRADY B-437 THERMAL TRANSFER PRINTABLE LABEL STOCK

Technical Data Sheet

BRADY B-437 THERMAL TRANSFER PRINTABLE LABEL STOCK

TDS No. B-437

Effective Date: 12/06/1999

Description:

B-437 is a polyvinylfluoride film with a thermal transfer printable topcoat and a permanent acrylic pressure sensitive adhesive.

B-437 is recommended for cable and wire bundle identification and label applications where self-extinguishing properties are required. B-437 has a specially designed topcoat which accepts thermal transfer printing.

B-437 has been judged to be self-extinguishing by laboratory testing, and exhibits good solvent and heat resistance. B-437 is available in white, yellow and various other colors.

Recommended ribbons are Brady R4300 and Brady R6200 black thermal transfer ribbons for optimal print performance.

Performance properties tested on B-437 printed with Series R4300 and R6200 ribbons using the BradyPrinter™ THT Model 300X thermal transfer printer. Printed samples were laminated to aluminum and allowed to dwell 24 hours before exposure to the indicated environments. Unless noted, results are the same for both ribbons.
