Fosroc Nitobond Ep Epoxy Bonding Agent, Hardener+ Resin, 4Lit

Product Details

Nitobond EPEpoxy resin concrete bonding agentUsesFor bonding new cementitious materials to existing cementitioussurfaces. For use on horizontal surfaces and on verticalsurfaces where mortar or concrete can be supported by formwork.Ideal for extensions and repairs to structural concrete inbuildings, loading bays, bridges, roads, bonded or granolithicfl oor toppings etc.AdvantagesNitobond EP can be applied by brush More overlay time : Enables to place the concrete upto 6hrs after applying Nitobond EP, without risk of delamination??? High bond strength : Bond strength is more than thetensile strength of good quality concrete Barrier coat : Acts as a ‘barrier coat' to the migration ofchloride ions from host concrete.DescriptionNitobond EP is based on solvent free epoxy resins containingpigments and fi ne fi llers. It is supplied as a two part materialin preweighed quantities for ready onsite mixing and use. Colouredcomponents - white base and green hardener - providevisual evidence that adequate mixing is achieved.Technical supportThe company provides a technical advisory service supportedby a team of specialists in the fi eld.Design criteriaNitobond EP is designed with an overlay time of 10 hrs at200C, 6 hours at 30 0C making it more suitable for use whereadditional steel reinforcement and formwork has to be fi tted orwhere temperature is high. The minimum application temperaturefor Nitobond EP is 10 0C.

The bonding agent shouldremain in tacky state after application for a minimum period of6 hours at 300C. There shall not be bond failure of the specimenwhen tested by slant shear method according to BS 6319pt 4, with M30 concrete.Application instructionsPreparationAll surfaces to be treated must be fi rm, dust free and clean.All laintence should be removed by etching with Reebaklensand wire-brushing. In some cases, the existing concrete mustbe chipped to a sound substrate. Where surfaces are contaminatedwith oil or grease, this should be removed by usinga strong industrial detergent or organic degreaser. Surfaceshould be washed thoroughly with water and dried before theapplication of Nitobond EP.MixingThe entire contents of the hardener can should be poured intothe resin container and the two materials thoroughly mixeduntil a uniform colour is obtained. To facilitate application attemperatures below 10 0C the separate components shouldbe warmed in hot water to a maximum of 25 0C before mixing.CoatingMixed Nitobond EP should be brush applied to the preparedsurface. The new concrete should be placed within 6 hoursat 300C to the Nitobond EP coated substrate, when it is in atacky state.LimitationsNitobond EP should not be applied when the temperature is
