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.

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® 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.
