Product Description

The Brady M21-750-499 B-499 nylon cloth tape is 0.75" wide and 16' long, has a permanent acrylic adhesive and a polyamide coating, and prints in black text on a white background with a matte finish. It can be used for marking cables and wires, and for general-purpose labeling on laboratory items, equipment panels, and faceplates. Nylon cloth tape is durable, has good chemical resistance, and resists abrasion. It is made from Brady's B-499 nylon material, which has a protective polyamide coating and permanent acrylic adhesive that keeps tape adhered to surfaces, even in autoclave, freezer, and liquid nitrogen environments (not recommended for outdoor use). This low-profile tape adheres well to surfaces that are smooth, rough, highly textured, or powder coated, as well as to irregular surfaces or surfaces with low surface energy. It is intended for use with Brady MP21, ID PAL, and LABPAL label printers.

Brady M21-750-499 printer label is an Underwriters Laboratories (UL) Recognized component that complies with UL969 labeling and marking standards when used with the appropriate printer. This product meets the requirements of a halogen-free material per Deutsches Institut für Normung (DIN) standard VDE 0472, part 815.
