FEATURES
- Std Roll Length: 16.66 yards
- 30% compression provides an excellent seal against light, dust and water in mechanically fastened assemblies
- Adhesive is on the unwind side
- Tensile=17PSI
- Thermal conductivity=.27
- Density=6#/cu.ft.
ADVANTAGES
- Excellent resistance to weather, fungi, and oxidation provides a long sealing life
- Superb closed cell structure of foam provides a positive seal
- Will not crack in cold temperatures
- Low force to compress means faster and easier formation of a positive seal
- Flexibility makes it easy to radius corners
- Low density sealant facilitates the assembly of large wall systems

- 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.
