ecotio2® does not contain any organic or synthetic materials and will not break down. This ensures it’s durability under the harsh New Zealand sun. The ecotio2® coating’s superhyrdrophilic properties prevent water forming droplets on a surface. Water quickly slips off the glass as a sheet. This, enhanced by the coatings anti-static properties, avoids the attraction of dust and other contaminants into residual water droplets and their ultimate deposition on the glass surface. Where there is little rainfall a light hosing will provide the same results.
