Definitions
- the present invention relates to a novel integrated coating system based on UV-A curable, solvent-borne coating materials. Moreover, the present invention relates to a novel process for the preparation of an integrated coating system based on UV-A curable, solvent-borne coating materials. Furthermore, the present invention relates to the use of the new integrated coating material system based on UV-A radiation-curable, solvent-borne coating materials and the prepared using the novel process coating system based on UV-curable UV-curable, solvent-borne coating materials in the automotive refinishing.
- the known spot repair methods have numerous disadvantages and are difficult to perform.
- the run-off zones of the clearcoat spray mist on the original finish are often too wide, which makes the optical adaptation of refinish and original finish difficult.
- the repair clearcoat may break away or rupture. This results in clearly visible edges that can even completely circulate the repair clearcoat, which is located directly above the original finish.
- the refinish works then because of the optically hard transition zones as a whole "glued plaster". Attempts have been made to solve the problems of breaking away or tearing and of the difficult adaptation of the optical properties in the run-off zones by applying so-called spotblenders over the uncured repair clearcoat. As a result, particularly "soft" transition zones are created and prevented that the repair clearcoat tears in the edge zones to the original finish.
- the known from the German patent application DE 100 43 810 A1 spot repair method has brought significant benefits.
- the grinding and / or polishing times can be reduced by more than 50% compared to conventional methods.
- the resulting refinishes no longer visually stand out from the original finishes.
- a ripping or breaking away of the repair clearcoat in the run-off zones is no longer observed.
- the refinish coatings are of such high quality that the spot repair process in question can also be used for car mini repair in the part of original paintwork in the line at the automobile manufacturer. Due to the high i. O. Rate are thereby achieved significant economic benefits.
- spot blender used in the known spot repair process is not fully suitable for use in spot repair processes involving actinic radiation, preferably UV radiation, in particular UV-A radiation, curable clearcoats are used (for "actinic radiation”, see German Patent Application DE 103 16 890 A1, page 6, paragraph [0035]).
