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® 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.

Colpor 200 is a cold applied, two part polyurethane sealant which is designed for joints in concrete paved areas. The capability of accommodating cyclic movements is retained by Colpor 200 throughout extremes of temperature conditions. Colpor 200 is resistant to fuel, oil and hydraulic fluid spillage, will not harden in cold weather nor become excessively soft or pick up in hot conditions. Colpor 200 has high durability and long service life which significantly reduces maintenance costs.

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.

Thioflex 600 is particularly recommended for use in high-rise buildings and other applications where access for subsequent maintenance will be difficult and the risk of early movement failure must be minimized. It is also suitable for sealing joints in brickwork, retaining walls, basements and subways. Thioflex 600 is available in gun and pouring grades. The gun grade is ideal for general application. It is packed in a ready to mix, 2.5 liter tin containing the base and curing agent in the correct proportions. The pouring grade for joints in horizontal surfaces is supplied in 5 liter packs with the base and curing agent in separate tins. Thioflex 600 pouring grade is recommended for initial sealing of expansion joints and stress relief joints in floors and sealing other horizontal surfaces.
