Curable coating compositions containing an aminoalklakoxysilane

摘要

The invention provides a curable coating composition containing a binder comprising - an organopolysiloxane (A) containing at least two silicon-bonded alkoxy groups per molecule and optionally a compound or polymer (B) containing at least one aliphatically unsaturated C=C group provided that the binder contains at least one aliphatically unsaturated C=C group or - a binder curable by radical reaction the binder containing an organopolysiloxane or a silane with at least one acrylate or methacrylate group or - an alkyd binder containing at least one aliphatically unsaturated C=C group, the composition containing optionally a curing agent (C) containing at least one primary or secondary amine group, and the composition also comprises an aminoalkylalkoxysilane (D) containing a primary or secondary amino group and a group having carbon to carbon unsaturation. This can improve properties related to overcoating interval, surface hardness, scratch resistance, weatherability, hydrophobicity, adhesion, application process, solvent resistance, slip, visual appearance.
