Overview
The Brady M21-750-499 label cartridge is a thermal transfer label solution designed for cable, wire, and equipment identification in industrial, laboratory, and commercial settings. Featuring polyamide-coated nylon cloth material with black text on a white background, this cartridge delivers crisp, legible markings on surfaces ranging from smooth to heavily textured. The B-499 material combines high pliability with aggressive permanent acrylic adhesion, making it suitable for challenging environments including temperature extremes and chemical exposure.
Key Features
- Polyamide-Coated Nylon Cloth (B-499): Durable material resists cold, chemicals, greases, oils, cleaners, and detergents
- High Pliability: Conforms tightly to curved surfaces such as wires, cables, and irregular shapes
- Aggressive Permanent Adhesive: Bonds reliably to stainless steel, textured ABS, polypropylene, and surfaces with low surface energy
- Low-Profile Design: Adheres to smooth, rough, powder-coated, and irregular surfaces without lifting or peeling
- Thermal Transfer Printing: Works with ribbon-based cartridge system for sharp, professional output
- Wide Temperature Range: Rated from −40°C to +90°C (−40°F to +193°F) for extreme environment applications
