CRL GT304-XCP24 Black 3/16" x 3/8" Butyl Architectural Glazing Tape - pack of 24

CRL Butyl Architectural Glazing Tape is an extruded, preformed tape furnished on release paper rolls. Based on a butyl rubber formulation with proven age and weather resistant properties, it is designed to create a long lasting, flexible weather seal between two surfaces that will be subjected to normal expansion/contraction and wind loading forces. It is used as an exterior primary spacing and glazing seal when glazing glass into a window sash; also used to seal other architectural surfaces such as metal to metal joints, wood to glass, metal to plastic, etc. The thickness is designed to be compressed approximately 10 percent at installation to accommodate surface alignments.
Typical Properties:
Base Polymer: Butyl rubber (polyisobutylene); SolidsContent: 100% solids (no asbestos); Cure Time: fully cured before application; Hardness: 20 durometer Shore "A" @ 77° (25°C); Temperature Range: Application 20°F (-7°C) to 120°F (49°C); Service -40°F (-40°C) to 190°F (88°C); VOCContent: 0%; Joint Movement: ±15% of joint width;Service Life: 20 year minimum.
Limitations: For applications above two floors use a spacer, shim, or a structural cap bead (such as silicone) to prevent over compression or use CRL 100+ Load Bearing Glazing Tape.
Applicable Standards: AAMA 804.3, 806.3, and 807.3. ASTM C1281
Good Glazing Practices: The following "Good Glazing Practices" are recommended when using CRL Glazing Tapes. Surfaces to be adhered should be free of frost or standing water, brushed clean, solvent washed (MEK, Toluene or Naptha) and wiped dry. At installation, positive contact and approximately 10 percent compression is recommended to fully marry surfaces to be joined. Glazing tapes kept under compression with clips or wedges provide the best seals.
