Boss Products 12501 Multi-seal Building Sealant White 10oz

Product Description

The BOSS PRODUCTS 12501 is a one-part, multi-purpose building and construction sealant packaged in a 10 oz cartridge. Formulated with USP Technology, it cures on exposure to atmospheric moisture to form a highly durable, flexible seal. The formulation is free from solvents and isocyanates, making it VOC compliant in all 50 states. It delivers primerless adhesion to a wide range of substrates including vinyl, aluminum, steel, concrete, wood, and glass, and can be applied to damp or non-porous surfaces without priming. HVAC, plumbing, and general construction trades use this sealant for joint sealing, penetration sealing, and weatherproofing applications.

This sealant is suited for both residential and commercial construction and mechanical service work. Its wide-temperature gunnability allows application in any season, and its non-slump properties make it usable in vertical, horizontal, and overhead joint orientations. The product also qualifies for LEED credits, making it applicable on green building projects. Trades including HVAC technicians, plumbers, and general contractors rely on it for exterior and interior sealing where flexibility and long-term adhesion are required.
