EkoEtch
EkoEtch is a product designed to prepare aluminium for coatings. Aluminium naturally oxidizes very quickly in the presence of air. Once a thin, invisible film of oxidation coats aluminium, it becomes fairly stable and is resistant to further corrosion. This becomes an issue when coatings are to be applied to the aluminium. Coatings will adhere to the oxidation and will come off with the oxidation. In order to adhere coatings to aluminium, this oxidation must be removed.
EkoEtch is an acid etch product that not only dissolves the oxidation but also slightly eats into the surface of the aluminium creating a porous surface that coatings can adhere to. Etching aluminium with EkoEtch is absolutely essential to achieving good adhesion of the coatings. Primer must be applied soon after etching or the aluminium will need to be re-etched. EkoEtch is only for aluminium and should not be used on any other substrate.
