Brady Adhesive Label Roll of 3000 Labels

Brady Thermal Transfer Printer Labels – 2 in. x 0.25 in., B-499 Matte Nylon Cloth, Permanent Acrylic Adhesive, 3 in. Core (MPN: THT-151-499-3)

The Brady THT-151-499-3 (commonly referred to as the THT-151-499 series) is a high-performance, industrial-grade thermal transfer printer label roll engineered for tight-space component identification, laboratory sample tracking, and precise electrical wire wrapping. Die-cut to an ultra-low profile measuring 2 inches wide by 0.25 inches high (50.8 mm x 6.35 mm), these rectangular labels are fabricated from Brady's signature B-499 polyamide-coated nylon cloth material. Featuring a highly pliable textile construction, they conform effortlessly to curved geometries and highly textured surfaces. Backed by an ultra-aggressive permanent acrylic adhesive, this system forms a reliable mechanical bond that resists flagging, unpeeling, and environmental degradation across an extensive thermal processing envelope.

Technical Performance and Design

• Pliable B-499 Nylon Cloth Substrate: Constructed from heavy-duty, matte white nylon cloth. The highly flexible textile material completely eliminates structural shape memory, ensuring the labels wrap tightly around thin-diameter wiring, cables, and sample tubes without popping up or flagging over time.

• Ultra-Aggressive Acrylic Adhesive Matrix: Outfitted with a high-cohesion, permanent acrylic adhesive layer. Formulated explicitly to bite into difficult, high-surface-energy (HSE) plastics, textured polymers, glass, and stainless steel housing components.

• High-Density Thermal Transfer Printing: Tailored to produce crisp text, linear barcodes, and alphanumeric data lines when paired with industrial desktop thermal transfer printers and high-durability resin ribbons (such as the Brady R4300 or R4900 series).

• Cryogenic and Autoclave Structural Endurance: Built to survive harsh environmental shifts, performing continuously in ultra-low mechanical freezers or liquid nitrogen vapor paths down to minus 40°C (-40°F) and high-pressure steam autoclave cycles up to plus 90°C (194°F).

Key Benefits and Applications

• Micro-Volume Lab Vial and Rim Tracking: The ultra-slim 0.25-inch height profile is an exceptional fit for side-wall indexing on long 4.0 mL vials, multi-well test plate outer rims, and low-profile conical cell containers.

• Industrial Wire and Cable Labeling: Widely deployed across telecommunications panel arrays and electronic wiring harnesses as a secure wrap-around flag that easily accommodates continuous physical flexing.

• Terminal Block and Component Indexing: Provides thin, sharp visual identification tracks along multi-point industrial terminal blocks, relays, circuit boards, and circuit switch surfaces.

• Resilience to Solvents and Handling: The rugged matte textile finish shields the printed layout against smudging, fading, or rubbing off when exposed to moisture, handling friction, and typical laboratory chemical vapors.
