AHEAD​ ​Ax/ECH

2-component​ ​Epoxy-Cement​ ​wearing​ ​course​ ​for​ ​vehicle-bearing​ ​surfaces Description AHEAD​ ​Ax/ECH​ ​is​ ​a​ ​cementitious​ ​two​ ​component​ ​copolymer-epoxy​ ​coating​ ​for​ ​the​ ​protection​ ​of​ ​concrete floors​ ​in​ ​demanding​ ​environmental​ ​conditions.​ ​Self​ ​smoothing,​ ​water​ ​based​ ​flooring​ ​system.​ ​It​ ​hydrates​ ​to form​ ​a​ ​excellent​ ​resistance​ ​to​ ​abrasion,​ ​chloride​ ​ions​ ​and​ ​chemicals.​ ​It​ ​is​ ​specially​ ​formulated​ ​to​ ​harden rapidly​ ​to​ ​form​ ​a​ ​hard​ ​wearing​ ​and​ ​durable​ ​surface​ ​in​ ​demanding​ ​internal​ ​and​ ​external​ ​environments. Thickness​ ​3-6​ ​mm Areas​ ​of​ ​application For​ ​car​ ​parks,​ ​and​ ​areas​ ​of​ ​heavy​ ​traffic.​ ​Ahead​ ​Ax/ECH​ ​is​ ​an​ ​ideal​ ​overlay​ ​for​ ​the​ ​ZEBRA​ ​cathodic protection​ ​system. Preparations The​ ​areas​ ​to​ ​be​ ​treated​ ​must​ ​be​ ​free​ ​from​ ​all​ ​unsound​ ​materials.​ ​Smooth​ ​surfaces​ ​should​ ​be​ ​roughened. This​ ​is​ ​achieved​ ​using​ ​totally​ ​enclosed​ ​shot​ ​blasting​ ​equipment,​ ​scarification,​ ​scabbling​ ​or​ ​grinding. Areas​ ​exhibiting​ ​signs​ ​of​ ​oil,​ ​grease,​ ​etc.,​ ​must​ ​be​ ​treated​ ​with​ ​a​ ​degreaser.​ ​Repeated​ ​applications​ ​may be​ ​required​ ​in​ ​areas​ ​where​ ​the​ ​contamination​ ​is​ ​persistent.​ ​In​ ​instances​ ​of​ ​heavy​ ​contamination,​ ​it​ ​may​ ​be necessary​ ​to​ ​use​ ​hot​ ​compressed​ ​air​ ​equipment,​ ​flame​ ​spalling​ ​or​ ​steam​ ​cleaning​ ​techniques. Vacuum​ ​to​ ​leave​ ​a​ ​thoroughly​ ​clean,​ ​dust​ ​free​ ​open​ ​textured​ ​surface. Priming Prime​ ​the​ ​clean​ ​surface​ ​with​ ​AHEAD​ ​Multiprimer​ ​Floor​ ​(apply​ ​as​ ​described​ ​in​ ​datasheet).​ ​The​ ​prepared substrate,​ ​previous​ ​coatings​ ​or​ ​concrete​ ​subbase​ ​must​ ​be​ ​thoroughly​ ​primed​ ​with​ ​AHEAD​ ​Multiprimer Floor​ ​before​ ​following​ ​layers​ ​of​ ​AHEAD​ ​Ax/ECH. Mixing When​ ​covering​ ​a​ ​bigger​ ​area​ ​ensure​ ​that​ ​a​ ​continuous​ ​supply​ ​of​ ​mixed​ ​AHEAD​ ​Ax/ECH​ ​is​ ​available. Pour​ ​the​ ​contents​ ​of​ ​Part​ ​A​ ​into​ ​a​ ​suitable​ ​mixing​ ​vessel.​ ​Slowly​ ​add​ ​Part​ ​B​ ​and​ ​mix​ ​for​ ​min.​ ​5​ ​minutes, until​ ​it​ ​is​ ​a​ ​homogeneous​ ​mass.​ ​Mix​ ​using​ ​a​ ​drill​ ​and​ ​a​ ​paddle​ ​specially​ ​designed​ ​to​ ​entrap​ ​as​ ​little​ ​air​ ​as possible.​ ​Repeat​ ​the​ ​same​ ​procedure​ ​until​ ​wanted​ ​amount​ ​is​ ​mixed.​ ​Do​ ​not​ ​spill​ ​content! Application Pour​ ​or​ ​pump​ ​the​ ​prepared​ ​AHEAD​ ​Ax/ECH​ ​onto​ ​the​ ​primed​ ​surface​ ​and​ ​spread​ ​to​ ​a​ ​minimum​ ​thickness of​ ​2​ ​mm.​ ​Roll​ ​the​ ​surface​ ​with​ ​a​ ​spiked​ ​roller,​ ​to​ ​remove​ ​entrapped​ ​air​ ​and​ ​to​ ​ensure​ ​a​ ​dense​ ​finish.​ ​To enhance​ ​skid​ ​and​ ​abrasion​ ​resistance​ ​by​ ​immediately​ ​broadcast​ ​suitable​ ​sand​ ​into​ ​the​ ​surface.​ ​Ensure that​ ​the​ ​sand​ ​is​ ​evenly​ ​distributed.​ ​Allow​ ​to​ ​cure​ ​for​ ​a​ ​minimum​ ​of​ ​4​ ​hours​ ​before​ ​removing​ ​any​ ​excess HS​ ​export​ ​code:​ ​3214​ ​9000

Important​ ​points To​ ​maximise​ ​the​ ​working​ ​life,​ ​Part​ ​A​ ​should​ ​be​ ​stored​ ​in​ ​chilled​ ​condition.​ ​Do​ ​not​ ​freeze! Experience​ ​has​ ​shown​ ​that​ ​condensation​ ​can​ ​form​ ​on​ ​surfaces​ ​treated​ ​with​ ​AHEAD​ ​Ax/ECH,​ ​particularly in​ ​cold​ ​conditions.​ ​This​ ​will​ ​cause​ ​a​ ​darkening​ ​of​ ​the​ ​AHEAD​ ​Ax/ECH​ ​and​ ​may​ ​retard​ ​the​ ​setting. Temporary​ ​variation​ ​in​ ​colour​ ​is​ ​normal​ ​initially​ ​and​ ​will​ ​even​ ​out​ ​during​ ​curing. Health​ ​and​ ​safety Classified​ ​according​ ​to​ ​CLP​ ​(EC)​ ​No.​ ​1272/2008 Safety​ ​datasheet​ ​is​ ​provided​ ​for​ ​this​ ​product.
