TML / UT Label Specs

TML Inspection Labels Thickness Measurement Location (TML) point labels are constructed with:

  • 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 is 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.

  • NDT Inspection LabelsTML / UT Label Installation:

  • Be sure application surface is at room temperature or slightly higher. The minimum application temperature for the adhesive is 58°F (15°C).

  • Clean and dry the application surface for maximum bond strength. The surface should also be free of loose particulate, such as dust, dirt and corrosion. A typical cleaning solvent is heptane or an industrial grade isopropyl alcohol.
  • Note: Acrylic adhesive requires 48-72 hours to achieve 90% of its ultimate bond strength. Several weeks are required to achieve 100% of ultimate bond strength. Higher initial bonds are achieved through increased rub down pressure.
