The invention relates to a non-volatile UV-stabilizing mixture for siloxane paint systems, containing hydrolizable silanes which in turn contain hydroxybenztriazols and epoxide groups. The resulting UV- stabilized paint systems are particularly suitable for use as anti-UV coatings for thermoplastics, especially aromatic polycarbonates.
L'invention concerne un mélange non volatil d'agents anti U.V. pour systèmes de peinture à base de siloxane, contenant des silanes hydrolysables comportant des hydroxybenzotriazols et des groupes époxyde. Les systèmes de peinture à action anti U.V. ainsi obtenus s'utilisent notamment en couche de protection anti U.V. pour des thermoplastes, en particulier des polycarbonates aromatiques.
