VINNAPAS® 4220 L is a dispersible polymer powder for dry mix mortars, specifically suited for self-leveling flooring compounds and screeds. It is based on a copolymer of vinylacetate and ethylene in the medium Tg range and belongs to the product class VINNAPAS® L which means that it improves the leveling and surface properties as well the stabilization of the fresh mortar. Cured mortars with VINNAPAS® 4220 L have improved adhesion, flexural strength, deformability and abrasion resistance.
