Ideal for rehabilitation of manholes, lining of outfalls, sewers and similar structures. Advantages „ Unaffected by a wide range of acids, alkalis and industrial chemicals „ Superior chemical and physical bond to virtually all substrates, dry or damp „ No need for priming concrete surfaces, therefore cutting labour costs and reducing risk of bad priming. Prepacked for ease of mixing. Equipment can be cleaned with water „ No harmful vapours present „ Strengths generally in excess of concrete to which material is applied. Excellent resistance to abrasion and impact „ Cured material provides long lasting waterproof barrier „ Unaffected by freeze-thaw attack which eliminates problems often encountered with conventional waterbased materials Description Nitomortar EL is a three component system consisting of epoxy resins without solvents and a special blend of chemical resistant fillers. The two epoxy components (both pourable) change to a gel upon mixing. Addition of the chemically resistant aggregate results in a thixotropic consistency for easy trowellability. A simple and cost effective material for overhead, vertical, horizontal patching and resurfacing to both dry and damp surfaces. The low odour, non-sag, and chemical resistant properties of Nitomortar EL make the ideal material for long lasting manhole wall rehabilitation. Nitomortar EL can be used in brick, block and precast concrete substrates and manholes. Provides a permanent impermeable, high strength, monolithic lining to the interior of manhole and trunk line walls and ceilings. A sprayable version of this product, Nitomortar ELS, is also available. Contact Parchem for further information. Properties The following results were obtained at a temperature of 20°C unless otherwise specified. Compressive strength at 7 days: 70 MPa Pot life: 3 hours @ 20°C 2 hours @ 30°C Initial hardness: 4 hours @ 20°C Full cure: 7 days @ 20°C Minimum application temperature: 5°C Chemical resistance: Performance of Nitomortar EL blocks continually immersed at 20°C: Bleach Excellent Detergent Excellent Sodium hydroxide 20% Excellent Sodium Chloride 20% Excellent Diesel fuel/petrol 100% Excellent Sulphuric acid 15% Excellent Design Criteria Nitomortar EL can be applied in sections up to 50 mm thickness for horizontal locations. The material should not be applied at less than 5 mm thickness. In vertical applications, the material should be “built-up” to a maximum thickness of 12 mm. Greater thicknesses than those specified above can be achieved by the application of subsequent layers. Application Instructions Preparation Clean the surface and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae. Roughen the surface and remove any laitance by light scabbling or grit-blasting. Saw cut or cut back the extremities of the repair locations to a depth of at least 5 mm to avoid feather-edging and to provide a square edge. Break out the complete repair area to a minimum depth of 5 mm up to the sawn edge. Prior to application of Nitomortar EL all active hydrostatic leaks must be stopped by the use of Vandex Plug, a rapid setting cementitious mortar. Mixing Nitomortar EL is supplied in the correct proportions to facilitate easy on site mixing. A slow speed electric drill with a suitable paddle can be used for efficient mixing. Satisfactory mixing can be achieved by removing the filler component bag and then thoroughly mixing all contents of the resin (part A) and hardener (part B) in the original container.
