- 10. A process for preparing a two-component coating composition of claim 1, comprising
- mixing the free polyisocyanates or the mixture of free polyisocyanates (3) with a first portion of the tris(alkoxycarbonylamino)triazine or the mixture of tris(alkoxycarbonylamino)triazines (2) to prepare second component (II), and
- mixing the hydroxy-functional binder or the mixture of hydroxy-functional binders (1) with a second portion of tris(alkoxycarbonylamino)triazine or the mixture of tris(alkoxycarbonylamino)triazines (2) to prepare first component (I).
- 11. The process according to one of claims 8 to 10, further comprising choosing the amounts of the constituents (1) to (3) so that the ratio OH:(NCO+NH--CO--OR) is from 1.0:0.5 to 1.0:2.0.
- 12. A method of coating a substrate comprising
- providing a two-component coating composition of claim 1,
- mixing component (I) and component (II) together to form a coating composition prior to application,
- applying the coating composition to a substrate, and
- baking the applied coating composition.
- 13. A method of coating a substrate comprising
- providing a two-component coating composition of claim 1,
- applying component (I) and component (II) to a substrate with the aid of a two-component application device to form a coated substrate, and
- baking the coated substrate.
- 14. The method of claim 12 wherein the two-component coating composition is a topcoat or a clearcoat.
- 15. The two-component coating composition of claim 3, comprising from 5 to 90% by weight of tris(alkoxycarbonylamino)triazine or of the mixture of tris(alkoxycarbonylamino)triazines, based on the overall amount of tris(alkoxycarbonylamino)triazine or mixture of tris(alkoxycarbonylamino)triazines and the free polyisocyanates or mixture of free polyisocyanates.
- 16. The two-component coating composition of claim 4 wherein the amounts of the constituents (1) to (3) are chosen in their ratios to one another such that the ratio OH:(NCO+NH--CO--OR) is from 1.0:0.8 to 1.0:1.5.
- 17. The two-component coating composition of claim 5, wherein in at least one or more of components (I) and (II) further comprise triazine compounds as UV absorbers.
- 18. The two-component coating composition of claim 7, wherein at least one or more of components (I) and (II) further comprise one or more members selected from the group consisting of organotin compounds, organobismuth compounds, tertiary amines, and mixtures thereof.
- 19. The process of claim 11 further comprising choosing the amounts of the constituents (1) to (3) so that the ratio OH:(NCO+NH--CO--OR) is from 1.0:0.8 to 1.0:1.5.
