Dowsil 121 Structural Glazing Sealant is a neutral-cure, RTV silicone sealant ideal for repair or replacement of structurally glazed glass and other substrates. It is equally suitable for on-site structural glazing including storefront systems or attachment of panel stiffeners as it is for in-shop structural glazing. Facade contractors and manufacturers now have a high-performance solution to the challenges posed by slow-curing one-part sealants, mixing challenges of multipart sealants and limited movement capability of tapes. Dowsil 121 Structural Glazing Sealant answers those challenges with a fast-cure, easy-to-install formulation.
