COLODUR ECO Aliphatic water-based polyurethane resin DESCRIPTION Colodur Eco is a waterborne high performance aliphatic polyurethane resin. It cures giving hard and flexible floor coatings, abrasion resistant. It provides a surface protection for heavily used floorings. This material does not discolour Density, clear and pigmented (g/cm3) 1,3 / 1.31 Viscosity (mPa.s) upon sunlight exposure, making it suitable for outdoor applications. Being almost solventless, it can be used in public areas with no need to close them. Colourless and pigmented versions are available. Viscosity Approximate Suggested uses include: Parking decks Industrial flooring. Tennis courts and recreational areas. General concrete flooring Sealing and surface protection of epoxy, polyurethane or cementitious self-leveling products.
