DU PU FLEX
High Performance PU Adhesive

    Professional, superior-technology, two-component polyurethane system with high elasticity and no slip, 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 high-expansion substrates.

Application

Thixotropic adhesive specially designed for requiring high elasticity, adhesion and for stability with thermal shock    with UV resistance.

Suitable Surface

Ceramic Tiles Glass Mosaic Large Size Tiles Humidity Sensitive Marble Wood and its Derivatives All Non Absorbent Substrates Natural Stone on Porous Surfaces Such Glass or Metal
