Product Details
- Product #HE925
Henry 925 BES Sealant is a premium, silyl-terminated polyether (STPE) polymer-based sealant that provides excellent weathering resistance, flexibility, low odor, and very low VOC. This one-part sealant is applied from cartridges or sausages using professional-grade caulk guns. Applied as a paste-like, non-sag compound, it cures with ambient moisture to an elastic, rubber-like state and is paintable once cured. Henry 925 BES Sealant is compatible for use in many Henry air barrier, flashing, roofing, and waterproofing systems.
Usage:
Suitable for diverse applications but is intended primarily for use as a component in Henry air barrier, flashing, waterproofing, and roofing systems. Used to detail terminations, penetrations, transitions, and joints as shown in Henry system architectural details. Henry 925 BES Sealant can also be used as an alternative to other elastomeric sealants (silicone, urethane, etc.) in above-grade construction applications, and is optimal for construction joints up to 1” (25mm) width that are subject to dynamic joint movement of up to + 35%. Henry 925 BES Sealant bonds well to many Henry® membranes as well as common construction materials including concrete, masonry, wood, and metal.
