B-473 is a glossy white polyester film with a static dissipative permanent pressure sensitive adhesive and a topcoat specifically formulated for thermal transfer printing.
B-473 is designed for applications where static charge is critical, such as topside of printed circuit boards and rating plates that utilize high quality/density alphanumerics, barcodes and graphics.
B-473 is static dissipative and can be used without fear of static charge. It has surface resistivity values in the static dissipative range between 106 and 1012 ohms/sq.
B-473 meets the requirement of EIA-541 "Packaging Material Standards for ESD Sensitive Items," in which a charged material must decay to 1% of its initial voltage in less than 2 seconds. B-473 is a UL Recognized component when printed with Brady R6000 or R4900 ribbons. B-473 is a CSA Accepted material when printed with Brady R6000 ribbon. See UL File MH17154 and CSA Acceptance Record LS 41833 for specific details.
