Fosroc Nitoseal MS 600

FOSROC SAINT GOBAIN: Fosroc Nitoseal MS 600 600ml

Nitoseal MS 600 is a single-component, medium-modulus silyl-modified polyether (SMP) sealant designed for construction joints in facades, curtain walling, perimeter glazing, and precast concrete panel connections. Its isocyanate-free chemistry eliminates the health risks associated with polyurethane sealants while delivering equivalent joint movement accommodation, making it a safer choice for applicators and building occupants. The sealant cures by atmospheric moisture to a flexible, paintable seal that adheres to concrete, masonry, aluminium, coated metals, and most building substrates without primer. Approved for contact with potable water, Nitoseal MS 600 is suitable for water infrastructure joints in addition to standard building envelope applications.
