Burn Characteristics: flame spread index - 5 - E-84 (UL 723); smoke developed index - 0 - E-84 (UL 723)
Leachables: Halogens and sulfur < 250 ppm - Mil std. 2041C; Mercury < 10 ppm - Mil std. 2041C
Easy to tear straight by hand
Excellent conformability
Contains no cloth scrim
Lower unwind force
Seven backing colors
Adhesive releases when accidently stuck to itself
Adhesive transfer resistance
Adhesive and backing will perform well and remove cleanly from surface after 1 hour at 250°F
Performs well when exposed to outdoor conditions, less prone to leave adhesive residue
Heat resistance

ADVANTAGES

Saves time, no additional tools needed, minimizes waste
Conforms to the surface to which it is applied
No exposed thread ends to wick water into the adhesive layer
Less effort to remove tape from roll, lesser user fatigue
Color-coding, easy on-site identification
Less waste
Minimal clean-up
Can be used in a wide variety of applications, less time spent on clean-up

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
