Pulverlackierte Substrate mit einem Decklack auf Basis epoxidgruppenhaltiger Silane

摘要

The invention relates to powder-coated substrates which on a surface coated with a powder-coating have a scratch- and abrasion-resistant top coat made of a lacquer consisting of: a) condensates on the basis of hydrolysable silanes with at least one non-hydrolysable substituent, where the hydrolysable silanes have an epoxide group on at least one non-hydrolysable substituent; b) a curing catalyst taken from the Lewis bases and titanium, zirconium or aluminium alcoholates; c) nanoscale inorganic solid particles having a particle size of between 1 and 100 nm; and d) at least one organic monomer, oligomer or polymer with at least one epoxide group.
