BRADY B-747 LASERTAB® MARKERS

TDS No. B-747
Effective Date: 21-Feb-2000

Description:

B-747 is a polyester film with an acrylic pressure sensitive adhesive and a printable coating specially formulated for laser printer and toners. B-747 is available in white or yellow.

B-747 is recommended for alphanumeric and barcode applications that require good solvent resistance and moderate to high temperature performance. This product works well on the topside of most circuit boards and IC's, as well as general labeling applications.

B-747 is formulated specially for laser printers. The material offers high print resolution, good solvent resistance, smudge resistance and moderate to high temperature performance.

B-747 white is a UL recognized component and CSA accepted material when printed with designated laser printers. See UL file MH17154 and CSA Acceptance Record LS 41833 for specific details.
