COATING AGENTS HAVING HIGH SCRATCH RESISTANCE AND WEATHERING STABILITY

摘要

The invention relates to coating agents which contain at least one hydroxyl group containing compound (A) and at least one isocyanate group containing compound (B). The invention is characterized in that one or more components of the coating agent comprise between 2.5 and 97.5 mole-%, based on the totality of structural units (I) and (II), of at least one structural unit of formula (I) -N(X-SiR"x(OR')3-x)n(X'-SiR"y(OR')3-y)m and between 2.5 and 97.5 mole-%, based on the totality of structural units (I) and (II), of at least one structural unit of formula (II) -Z-(X-SiR"x(OR')3-x) as additional functional components.
