Nitoseal MS300 is a one part, high modulus sealant based on hybrid silyl modified polyether technology. It has a rapid rate of cure and forms a tough elastomer capable of supporting heavy wheel loads.
Nitoseal MS300 may be applied between 6mm and 20mm wide, for trafficked joints (up to 40mm non-trafficked). In most cases it is recommended to form a sealing slot with a square cross-section, subject to a minimum 10mm depth. To ensure the sealant operates within its stated movement accommodation capacity the sealing slot widths should be designed in accordance with the recommendations of BS6093.
