Thickness Measurement Location (TML) Labels
Product Specifications & Pricing:
The typical label is 3.5 mil matte silver mylar polyester material. The matte coating resists degradation from scuffing, chemicals, moisture and wide temperature fluctuations. The adhesive is a high performance acrylic for excellent bonding to metals, HSE plastics and a wide variety of painted surfaces.
Leachable chloride, fluoride and sulfur in the adhesive, as measured by ion chromatography – PPM – is 3, less than one, and less than one, respectively.
Typical values for continuous temperature resistance range between -40F and 300F. Minimum application temperature is 58F.
Label NDS-D: Measures 1”x 2” with a .75” diameter opening for inspection and a blank space for on-site inscription.
A 4.0 mil environmental protectant laminate is included as an integral part of the label with a removable tab to overlay the inscribed marking.
The standard label is bright orange.
Wording: “DO NOT REMOVE, NDT PT”
Label NDS-E: Measures 1.5” in diameter with a 4.0 mil environmental protectant laminate.
The standard label is bright orange.
Wording: “TML LOCATION, DO NOT REMOVE”
Label NDS-F: Measures 1.25” in diameter with a .75” diameter opening. A 4.0 mil environmental protectant laminate is applied at the factory.
The standard label is bright orange.
Wording: “UT LOCATION, DO NOT PAINT”
Label NDS-H: Measures 1.5”x 1.5” with a .625” diameter opening and a blank space for on-site inscription. A 4.0 mil environmental protectant laminate is supplied as an integral part of the label with a removable tab to overlay the inscribed marking.
The standard label is bright green.
Wording: “DO NOT PAINT, NDT POINT”
TML Label Installation Instructions:
Minimum application temperature for the adhesive is +58 F (+15 C). For best bonding conditions, application surface should be at room temperature or slightly higher.
For maximum bond strength, the surface should be clean and dry. The application surface should be free of loose particulate, such as dust, dirt and corrosion. A typical cleaning solvent is heptane or an industrial grade isopropyl alcohol. (Consult the manufacturer’s Material Safety Data Sheet for proper handling and storage of solvents.)
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.
