Hot-poured, rubber bitumen horizontal joint sealing compounds, black in colour. Four grades Nitoseal MBA2, Nitoseal MBA1, Nitoseal MB77 and Nitoseal MB99.
Nitoseal MB99 formerly known as Pliastic 99 is similar in composition to Nitoseal MB77 but has a higher softening point for use in hot climates where the ambient
temperature never falls below 4oC and is expected to rise above 40oC. At higher ambient temperatures the properties of Nitoseal MB99 approximate to those given for Nitoseal MB77 in temperate climates.
Used for sealing horizontal movement and construction joints in concrete pavements and floor slabs. Typical areas include;
■ Pavements, roads and traffic surfaces
■ Water excluding substructures
■ Water retaining structures including reservoir floors and roofs, swimming pool substructures and irrigation canal floors.
■ An economical sealant for horizontal and inclinedjoints up to 1 in 20
■ Resists dirt and ingress of grit associated with trafficked pavements
■ Suitable for sealing joints in potable water tanks
■ Good adhesion to concrete and asphalt surfaces
