Application Guide

Product Data Sheet

 

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. DOWSIL 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, DOWSIL 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.
