Brady THT-21-434 Metallized Glossy Polyester with 2 mil Adhesive Labels 3 in W x 300 ft L Silver
Formulated from Brady B-434 Industrial Technical Substrate with permanent acrylic adhesive. Engineered for 3" W × 300 ft Roll industrial labeling applications.
Engineered Technical Features
- Glossy, light gray finish gives labels a rating and serial plate appearance
- Labels are designed to withstand numerous solvents and variable temperatures when applied to various surfaces
- UL approved;CSA accepted
- Service temperature of -40 to 194° F (-40 to 90° C)
- This roll has i75-series smart properties on the core that when used in the Brady i7500 printer in conjunction with i75-series smart ribbons, eliminates the need to adjust heat, speed , sensor location and mode, eliminates the need to calibrate out blank wasted labels, and warns the operator if a non-approved ribbon is used with this roll.
- This metallized label roll is supplied on a 3 inch core that has a thicker 0.66 inch wall to enable addition of i75-smart functionality.
- If used in any other 3 inch core printer this roll will function as a manual roll
- A ribbon is required to print this material. Use Part Number IP-R6002 for the BradyPrinter i5100 or BRADY IP® Series Label Printer; use R6002 for a different printer
