POLYUREA COATING SYSTEMS FOR CONSTRUCTION WATERPROOFING
The present invention relates to a 2K coating system consisting of two components (A) and (B) being separate from each other, wherein (A) comprises at least one constituent (a1) containing at least one aromatic moiety and bearing on average at least two primary and/or secondary amino groups, wherein (B) comprises at least one constituent (b1) containing at least one aromatic moiety and bearing on average at least two isocyanate groups, wherein each of (A) and (B) has a solid content of at least 95 wt.-%, based on the total weight of the respective component, the amount of any fillers present in component (A) does not exceed 45 wt.-%, based on the total weight of component (A), and constituent (b1) present in component (B) bears carbodiimide and/or uretonimine units as well as at least one structural unit (1), a coating composition obtainable by mixing components (A) and (B) of the inventive coating system, a use of said coating composition as sealant, in particular for providing a waterproof coating on a substrate, a method of applying the coating composition to a substrate and in particular a method of sealing a surface of a substrate such as concrete and/or steel, and a coated substrate such as a sealed concrete and/or steel substrate obtainable by this method.
