A one-part, medium-modulus, elastomeric sealant designed for general weathersealing. It is a silicone formulation that cures to a flexible and curable silicone rubber building joint seal.
One of the most economical options for quality silicone weathersealing, DOWSIL™ 791 Silicone Weatherproofing Sealant is a neutral-cure, one-part sealant that quickly cures to a durable, flexible seal that can accommodate significant joint movement. Especially suited for perimeter sealing around doors and windows, it's also excellent for sealing expansion and control joints, precast concrete panels, curtainwall and mullion joints, and internal seals and end dams.
