Technical Information

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 internal trafficked flush joints and up to 40mm wide, for non-trafficked / recessed trafficked joints. In most cases it is recommended to form a sealing slot with a square crosssection, 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.

Where To Use

Nitoseal MS300 is suitable for sealing saw-cut and movement joints in internal floors, and external joints where abrasion resistance is required. It can also be used for external facade joints where a tougher seal is required.
