Concrete Structure Protective Coatings

Epoxy-resin coating without the use of solvent for strengthening water retaining structure Uses Nitocote EP405 is preferably recommended for water-proof and lining of water-retaining structure and surface-touching with foodstuff. The cured concrete film withstands corrosion, chemical damage abrasion, is befitting for application in Breweries, Dairies, Food Meat Processing Plants, Reservoir, Silo, Tanks and Water Treatment Plants. The film of cured concrete is non-toxic and complies with standards of IS 9833 - 1981. Advantages Food grade & Hygienic - CFTRI approved for suitability to potable water and food stuff storage. Compatible with all substrates - Can be applied directly on to mild steel and concrete Aesthetic - Forms a smooth, glossy and to easy clean surface on curing Abrasion resistant - Exceptional resistance to abrasion and to a wide range of chemicals Corrosion resistant - Does not contain any metallic particles Chemical resistant - Proven against a wide range of industrial chemicals Solvent free & Non - toxic - No odour during application and can be used in confined areas. Description Nitocote EP405 is a two pack, solvent free, epoxy resin material. It is supplied in pre-measured quantities ready for site mixing and use. The material cures to provide a smooth, hygienic and tough finish which is suitable for contact with potable water and foodstuffs. It is available in blue and white colours. Technical Support Fosroc provides a technical advisory service supported by a team of specialists in the field. Design Criteria Nitocote EP405 is designed to be applied in two coats to achieve a minimum total dry film thickness of 200 microns. To achieve the correct protective properties, Nitocote EP405 must be applied on to the substrate at the coverage rates recommended. Specification Clauses Potable water / waterproofing lining The tank/reservoir lining shall be Nitocote EP405, a two pack epoxy coating specifically designed for contact with potable water. The cured film shall comply with the requirements of IS9833 - 1981. Application Instructions Preparation Concrete surfaces All surfaces must be smooth, sound and free from debris, loose or flaking material and areas of standing water. Surfaces must be free from contamination such as oil, grease, dust, loose particles and organic growth. Concrete surfaces must be fully cured, laitance free and free from any traces of shuttering, release oils and curing compounds. All surfaces should then be grit blasted to remove all foreign matter and open up blow-holes, and provide a suitable key for Nitocote EP405. All blow holes and imperfections should be filled with Nitocote VF / Nitomortar FC. Steel Surfaces All surfaces should be grit blasted to obtain bright metal surface. The lining work should be programmed so that newly cleaned steel is coated as soon as possible before the formation of rust or scale. Mixing The contents of the base can should be stirred thoroughly to disperse any settlement. The entire contents of the hardener can should be poured into the base container and mixed thoroughly until a uniform consistency is obtained, taking particular care to scrape the sides and bottom of the container. It is recommended that mechanical mixing be employed, using a mixer or a heavy duty, slow speed electric drill fitted with a paddle. Application Any surfaces should be treated with two coats of Nitocote EP405.
