It is bonded in position with Nitomortar AP, a two-part epoxy adhesive specifically formulated for the purpose. Emer-Band may be used to seal joints in car park decks, podiums, balconies, walkways and other elevated structures, where the Emer-Band can be protected from mechanical damage by a cover plate. It can also be used for overstrapping joints in basements, subways, tunnels, refineries and substructures in general. Emer-Band can also be used on silos, roofs as well as water immersed applications such as tanks, sewers, reservoirs, pipelines and swimming pools where the joint movement may exceed the capability of conventional gun applied elastomeric sealants. Advantages „ Forms a tough, flexible joint flashing „ Accommodates continuous, and pronounced cyclic movement „ Range of sizes available to suit most applications „ Excellent resistance to UV and weathering „ AS4020 approved for potable water „ Application to dry and damp surfaces „ Excellent adhesion to most construction materials „ Performance not affected by climatic extremes „ Rot resistant „ Emer-Band can be heat welded for the continuity of long joint lengths „ Perforations along the edges of the Emer-Band provide a mechanical fixing element in addition to the excellent chemical bond offered by the Nitomortar AP „ Resistant to a wide range of chemicals Description The Emer-Band joint sealing system consists of two components; Emer-Band Hypalon Tape: a Hypalon rubber strip available in 1 mm and 2 mm thicknesses and a range of standard widths including 100 mm, 150 mm and 200 mm. Special widths can be manufactured to order. Nitomortar AP: a moisture tolerant, non sag, two part epoxy adhesive specifically formulated to give optimum adhesion to the Emer-Band and construction materials. Emer-Band Tape is supplied in rolls 25 m in length for the 1 mm thick material. When the length of joint exceeds the roll length, the Emer-Band strip is joined by heat welding with a hot air gun. Emer-Band Tape is bonded to the structure on both sides of the joint using Nitomortar AP. Properties Data quoted is typical for this product but does not constitute a specification. Emer-Band Tape Colour: Concrete grey Service temperature: Minus 10°C to plus 80°C Tensile strength: 5.7 MPa Elongation at break: 625% ts (50% total) Nitomortar AP Colour: Concrete grey Specific gravity: 1.7 ( mixed ) Application 5°C to 50°C temperature: Pot life: 30 min @ 25°C Initial cure: 24 hours Full cure: 7 days Adhesive bond strength: Exceeds tensile strength of concrete Movement accommodation: Emer-Band used in conjunction with Nitomortar AP can accommodate continuous cyclic movements which result in the de-bonded area being extended up to 100% of the de-bonded width e.g. application with 50 mm unbonded area can accommodate 50 mm movement Maintenance There are no special requirements, however, any damage should be repaired by exposing the damaged area, cleaning the surface and replacing the strip. Specification clauses Where indicated on the drawings joints shall be sealed with a flexible Hypalon rubber bandage membrane having a tensile strength greater than 5.5 MPa and an elongation greater than 600%. Such a bandage membrane is Emer-Band supplied by Parchem. Emer-Band shall be installed strictly in accordance with the manufacturer’s printed instructions. June 2014
