Dow Structural sealants are designed for site or factory glazing and curtainwall production, ideally suited for silicone structural bonding applications for the hurricane or impact-rated windows and doors. These sealants use silicone adhesive to attach glass, metal, or other panel material to the structure of a building. They exhibit excellent mechanical properties, high ultimate tensile strength, un-primed adhesion properties to most building substrates, and excellent weather-ability.
