Hydro oil-repellent waterproof
DRAI hydro repellence is superior to any other organic or inorganic compound, with unimaginable values of oil-repellency. It can be used on any surface. The high water repellency prevents water from coming into contact with calcium carbonate – the major component of building materials - avoiding deterioration by carbonization. The impossibility for water to penetrate into building materials avoid structure cracking and the formation of algae and molds. Even pollutants - chemicals or dirt – can’t settle on the surface avoiding it gets dirty and deteriorate.
Drai is an acrylic copolymer modified with fluorinated groups: the acrylic components facilitate adhesion to stone surfaces, while the fluorinated groups, positioned externally, ensure hydro-oil repellency.
• Drai penetrates very deeply into capillary pores: many tests showed penetrations up to 4-5 mm into materials. Tests have been carried out on different types of surfaces: concrete, earthenware mortars, tuff, carparo, various marbles (Carrara marble, flowered bardiglio, Verona red marble, yellow Siena marble, granite, travertine, etc..), paints and lime-based coatings, marmorino: the results have always been very satisfactory.
• Drai, is invisibile once it’s dried – materials natural appearance keeps totally unchanged.
• Drai is permeable to vapour; the permeability of the different processed surfaces keeps totally unchanged.
• Drai is chemically stable and does not change with exposure to UV rays.
