IQ MS Structural Sealant
SKU: Modified silane high-strength sealant · IQCON 3222 / 3444
High-strength, paintable MS sealant for demanding joints.
About
IQ MS Structural Sealant is a one-component, moisture-curing modified silane sealant formulated for high-strength bonding and sealing beyond the reach of standard sealants. Solvent-free and isocyanate-free, it cures neutral with low VOC and no staining, delivers fast, reliable bonding strength across metal, most plastics and building materials, and can be painted over once cured. It is suitable for structural bonding and fixing applications such as metal structures, mechanical equipment and building doors and windows — though not for sunrooms or curtain wall (structural glazing) projects.
