DOWSIL 791 is a low-modulus, neutral-cure silicone sealant specifically formulated for use in structural and weatherproofing glazing applications, curtain walling, and facade sealing. Its low modulus means it accommodates significant movement in joints without delaminating from the substrate, making it ideal for glazing into metal and structural systems. Available in a range of standard colours.
