DU PU Flex is a professional, superior-technology, two-part polyurethane system with high elasticity and anti skid property, suitable for high-resistance laying on flooring and wall of homogeneous and ceramic tiles, glass mosaic, large-size tiles, humidity sensitive marble and natural stone, on deformable and also non-absorbent substrates, wood and derivatives. The DU PU Flex technology ensures superior- performance adhesion for laying ceramic tiles and natural stone on porous surfaces such glass or metal. DU PU Flex provides balanced thixotropy and superior-performance elasticity ensured by the use of stabilized polyurethane resins and micronised, pure mineral fillers, for rapid and secure laying operations on high deformable and highexpansion substrates.
