COATING AGENTS HAVING HIGH SCRATCH RESISTANCE AND WEATHERING STABILITY

摘要

Disclosed are coating compositions comprising at least one hydroxyl-containing compound (A) and at least one isocyanato-containing compound (B), wherein one or more of the constituents of the coating composition comprise between 2.5 and 97.5 mol %, based on the entirety of structural units (I) and (II), of at least one structural unit of the formula (I) -N(X-SiR''x(OR')3-x)n(X'-SiR''y(OR')3-y)m (I) and between 2.5 and 97.5 mol %, based on the entirety of structural units (I) and (II), of at least one structural unit of the formula (II) -Z-(X-SiR''x(OR')3-x) (II).
