 Silicone Structural Glazing Sealant

Dow Corning® 121 Structural Glazing Sealant

With a fast cure and 1:1 mix ratio, Dow Corning® 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. Dow Corning® 121 Structural Glazing Sealant is ideal for assembly, installation or repair of structurally glazed glass and other substrates, featuring:
 
  • Easy-to-use, user-friendly dispensing - offering a unique 1-to-1 ("121") mix ratio, Dow Corning® 121 Structural Glazing Sealant is supplied in a two-part cartridge, complete with a static mixer
  • On-site or in-shop suitability - portable for on-site structural glazing as well as in-shop structural glazing
  • Enhanced productivity- cures in just one day (24 hours) compared with 14-21 days for single-part sealants
  • Cost savings - 1:1 mix ratio eliminates the need to invest in specialized pumps and mixing equipment and related maintenance costs
  • Superior silicone performance - outperforms organic weatherseals and structural tapes
  • Service and support from a trusted source - including a full range of project management services, as well as an available 20-year Structural Adhesion Limited Warranty
