Test Measurement Labels


  • 3.5 mil matte silver mylar polyester material with a 1.0 mil UV laminate. The matte coating resists degradation from scuffing, chemicals, moisture, and wide temperature fluctuations.
  • High-performance acrylic adhesive for excellent bonding to metals, HSE plastics, and a wide variety of painted & textured surfaces.
  • Low-leachable chloride, fluoride, and sulfur are in the adhesive.
  • Typical values for continuous temperature resistance range between -40°F (-40°C) and 300°F (149°C). The minimum application temperature is 58°F.
