About this product
DOWSIL™ 121 Structural Glazing Sealant is a two-part silicone formulation designed specifically for use in structural glazing applications in field and factory applications. The material is supplied in a two-part cartridge in which the catalyst is a smooth, white paste and the base is tinted either black or gray. Once catalyzed, the material cures into a medium modulus, flexible silicone rubber that is flexible for use in structural and weatherseal applications. It can be used in deep, narrow joints to obtain a complete cure. DOWSIL™ 121 Structural Glazing Sealant cures in deep section within 24 hours and generally achieves full adhesion within 48 hours. However, full cure time depends on joint design, substrate type, temperature and humidity. A fast-curing structural silicone sealant for use in structural and weatherseal applications. With a fast cure and 1:1 mix ratio, DOWSIL™ 121 Structural Glazing Sealant answers the challenges facade contractors and manufacturers face with slow-curing, one-part sealants, mixing challenges of multipart sealants, and limited movement capability of tapes. Features: Easy-to-use, user-friendly dispensing On-site or in-shop suitability Enhanced productivity Cost savings Superior silicone performance Service and support from a trusted source
