The present invention relates to a radiation-curable coating composition, especially for producing a scratch-resistant coating on polycarbonate surfaces, comprising at least one urethane acrylate of an isocyanurate trimer of 1,6-hexamethylene diisocyanate and butanediol monoacrylate. The invention also relates to a method for producing scratch-resistant coatings on polycarbonate surfaces, to the use of the coating composition, and to a substrate coated accordingly.

Radiation-curable coating composition, method for producing scratch-resistant coatings, use of the coating composition, and substrate coated with a coating composition

Described is a clearcoat coating composition, its use, and a process for preparing the clearcoat coating composition. The clearcoat coating composition comprises (A) at least one polyester having an OH number of 80-250 mg KOH/g; (B) at least one butanol-etherified melamine-formaldehyde resin having a crosslinking onset temperature between 65&#xb0; C.-100&#xb0; C. lower than the crosslinking onset temperature of hexamethoxy-methylmelamine; (C) at least one butanol-etherified melamine-formaldehyde resin having a crosslinking onset temperature between 30&#xb0; C.-60&#xb0; C. lower than the crosslinking onset temperature of hexamethoxymethylmelamine; (D) at least one organic urea compound as rheological assistant; and (E) at least one acid catalyst.
