Abstract
A composition includes a first component containing at least one polyaspartic acid ester (P1-1) and optionally a polyaspartic acid ester (P1-2) and a mixture of various polyetheraspartic acid esters (P2), and of a second component containing at least one aliphatic polyisocyanate (B1) and at least one isocyanate prepolymer (B2). The composition is particularly suitable as a cover coating composition. Said composition has a good adhesion on polyurea and polyurethane membranes, in particular roof membranes, and has drying times of less than 120 min, an elongation at break of 80-200% and a tensile strength of more than 6 N/mm.
