A self-adhering tape seal made from resilient, open-cell polyurethane foam impregnated with a waterbased acrylic-modified asphalt emulsion and then compressed to a sealing density level appropriate to the application
Typically, higher compression levels are required for watertightness in water run-off applications; lower compression can be used, for example, for snow seals at roof ridges
Replaces and outperforms liquid and butyl-tape sealants as well as closed-cell and unimpregnated open-cell foam closures
Used to seal out dust, air, wind-driven snow, and moisture through joint details in metal buildings and roofs
Ideal as a filler in expansion/compression joints subject to movement from thermal expansion and contraction, and as a gasket in mechanically fastened, non-moving applications such as lap seams
Suitable for use against metal, plastic, wood, concrete, and other materials common in metal building structures
Will not dry out and become hard or brittle
UV-stable
Highly resistant to bugs and vermin
Will not extrude from between joints like caulk or butyl tapes
Conforms to contours and fills gaps
Maintains a seal during thermal expansion and contraction of building panels
Excellent compressibility and recovery (minimal compression set)
Good thermal and sound insulator
No shrinkage or blow-out due to closed-cell breakage
Supplied with self-adhesive on one side
After removal of packaging, material begins gradual expansion - more slowly in cold weather than in hot
Use in all applications where the material will be allowed to expand to fill voids or follow panel contours
Use in flat-on-flat "gasket" applications where the material will be held at a high degree of compression by fasteners such as clips, screws, etc
