Modern, high-quality exterior insulation and finish systems (EIFS) require the use of polymeric binders. VINNAPAS^® dispersible powders are polymeric binders that enhance the adhesive and reinforcing mortars in exterior insulation and finish systems. They are designed to selectively modify the properties of the mortar and the whole system. VINNAPAS^® dispersible powders and dispersions contribute good adhesion to all substrates, are flexible enough to accommodate differing expansion coefficients of the materials used, and offer optimal shelf life and durability. Since EIFSs are constantly exposed to the weather, effective protection against water is essential. VINNAPAS^® can be used for modifying EIFSs to suit the vagaries of all climates.
