Nitoseal

Nitoseal® MS100 is a tough, durable elastomeric joint sealant. It is based upon hybrid silyl modified polyether technology. It is suitable for use over a wide range of external and internal building applications and has excellent weather resistance. Nitoseal® MS100 has excellent primer-less adhesion to a wide range of common building substrates and does not stain concrete, marble and other masonry surfaces.

Nitoseal® PU40 is a one part, low modulus gun grade elastomeric sealant based on polyurethane technology. Nitoseal® PU40 may be applied to joints between 5 and 35mm wide. To minimize stress imposed on the joint sealant, all moving joints should be designed to an optimum width to depth ratio of 2:1 with an overriding minimum depth of 5mm for non-porous surfaces and 10mm for porous surfaces.

Nitoseal® MS60 is a one part, low modulus sealant based on hybrid silyl modified polyether ("MS") technology.

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 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.

Nitoseal® MS600 is a one part medium modulus sealant based on hybrid silyl modified polyether technology. It has a fast rate of cure and forms a tough, highly durable and water resistant elastomer.

Nitoseal® PU280 two-part pouring grade sealant is formulated from a blend of epoxy and urethane polymers. The mixed sealant is self leveling and can be poured directly into hori- zontal joints to form a tough resilient seal possessing a limited degree of flexibility.

Nitoseal MB150 is a hand applied putty for vertical or inclined joints in water retaining structures.

Nitoseal® PE290 three-component flexibilised polyester based sealant cures to form a tough resilient seal with a limited degree of movement. The material is self leveling and can be poured or gunned directly into horizontal slots. Nitoseal® PE290 will adhere to both concrete and asphalt surfaces that have been well prepared whether dry or damp.

Nitoseal PU220PF is suitable for use in sewage treatment works, petrochem storage tanks, sea water intakes and sea walls, subject to tidal conditions. It is a bio-degradation resistant sealant.

Nitoseal® PU220 is a two part polyurethane formulation which is blended with high grade pitch which cures to form elastomeric, highly resilient seals with excellent recovery properties. It does not exhibit the characteristic disadvantages of conventional bituminous or tar based compounds such as embrittlement, thermo-plasticity and cold flow tendencies. Cured Nitoseal® PU220 seals are watertight and highly resistant to weathering and aging. Nitoseal® PU220 is supplied as a black, gun grade sealant suitable for both vertical and horizontal joints.
