Tremco 440 Tape is a 100% solid Polyisobutylene cross-linked butyl, perfomed sealant.
Basic Uses
Tremco 440 Tape is used for non-compression glazing of vision lites and spandrel panels in PVC metal and wood frames, in low-rise building construction, not exceeding 75 UI. Tremco 440 Tape is also used for lap sealing between panels such as steel, aluminum and porcelain as well as a variety of other joints subject to shear between similar and dissimilar materials.
Applicable Standards
Tremco 440 Tape meets the requirments of AAMA 800-92 specifications 804.3 and 807.3.
Limitations
Not for use in joints subject to continuouse water immersion or temperatures exceeding 158 °F (70 °C). A compatibility test is required when used in conjunction with sealants other than approved Tremco silicone sealants.
Not for use with lites of glass over 75 UI (1905 mm). As the size of the lites approaches 75 UI (1905 mm), 50" (1270 mm) in height or 8 to 10 ft² (.743 to .929 M²) in area, a higher performance glazing system should be considered.
