Ideal for rehabilitation of manholes, lining of outfalls, sewers and similar structures. Nitocote EP500 can be used in brick, block and precast concrete manholes. Nitocote EP500 provides a permanent impermeable, high strength, monolithic lining to the interior of manhole walls. Advantages „ Enhanced formulation provides increased resistance to a „ Resistant to biological attack „ Superior chemical and physical bond to virtually all „ No need for priming concrete surfaces, therefore cutting „ Prepacked for ease of mixing „ 100% solids content - contains no solvent „ Strengths in excess of most concrete substrates to which „ Cured material provides a long lasting waterproof barrier „ Unaffected by freeze-thaw attack Description Nitocote EP500 is a a new generation epoxy lining mortar based on the latest epoxy resins and chemical technology to provide a lining system that has increased hydrophobic properties meaning the chemical resistance is significantly enhanced. The two component system has a high epoxy content and fine graded fillers ensuring the material is easy to spray as well as ensuring a tortuous path for sulphuirc acid penetration. Technical Support Parchem offers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, the company offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. INDEX 70 Technical Data Sheet wide range of acids and alkali’s, specifically sulphuric acid found in waste water environments substrates, dry or damp labour costs and reducing risk of bad priming material is applied. Excellent resistance to abrasion and impact Design Criteria Nitocote EP500 is spray applied generally in layers between 2 mm and 5 mm per layer - the minimum total thickness should be 2 mm. Consult your Parchem sales office for further details. Properties The following results are typical for the product but do not constitute a specification. Compressive strength 28 days: 40 MPa Pot life: 1 hour @ 25°C Initial hardness: 4 hours @ 25°C Minimum “back to service” time: March 2014 Page 1 6 hours @ 25°C Full cure: 7 days @ 25°C Adhesion to concrete: >1 MPa substrate failure Note: Cure times will increase by a factor of 2 for each 10°C reduction in temperature. Minimum application Temperature: 5°C Chemical resistance: Performance of Nitocote EP500 blocks continually immersed at 23°C for 28 days: Bleach Excellent Detergent Excellent Sodium hydroxide 25% Excellent Diesel fuel/petrol 100% Excellent Sulphuric acid 50% Excellent Nitric Acid 25% Colour Change Excellent Phosphoric Acid 25% Excellent Hydrochloric Acid 25% Excellent Toluene 100% Excellent Kerosene 100% Excellent Application Instructions Preparation Clean the surface and remove any dust, unsound concrete, oil, paint, grease, corrosion deposits or algae. Roughen the surface and remove any laitance by light scabbling or grit-blasting. Where possible, saw cut or cut back the extremities of the repair locations to a depth of 3 mm to avoid feather-edging and to provide a square edge. Prior to application of Nitocote EP500 all active hydrostatic leaks must be stopped by the use of Vandex Plug, a rapid setting mortar. Fosroc® Nitocote EP500 March 2014
