A metering and mixing device contains a multichamber cartridge and a cartridge holder having a reception container for the multichamber cartridge and a compressed air connection and a connection for an application device. The reception container has an internal tube arranged coaxially to the walls of the cartridge holder and equipped with static mixing elements. The multichamber cartridge contains an upper portion having a directional valve, a middle portion configured as a tubular empty space surrounded by at least two chambers arranged tubularly in the direction of the longitudinal axis of the cartridge, and a lower portion having a piston for each chamber. The multichamber cartridge is arranged in the cartridge holder such that the inner wall of the inner tube of the multichamber cartridge bears, leak-tight, against the outer wall of the tube of the cartridge holder.

The present disclosure provides multicoat systems exhibiting ultraviolet (UV) stability after ultraviolet exposure and moisture exposure. The systems comprise at least one primer (G), at least one pigmented coating (P) disposed on a surface of the primer, and at least one ultraviolet (UV) absorber which has an absorption maximum of at least 370 nm. The pigmented coating (P) may be comprised of two or more coatings (P1), (P2) to (Pn). The multicoat systems may also comprise a transparent coating material (T) to form a transparent coating (K). The present multicoat systems demonstrate ultraviolet stability, reduced delamination of the pigmented coat from the primer and are available in a variety of shades for use in the finishing, refinishing and coating of component parts. The present disclosure also provides for a process for producing the multicoat system, and provides for the use of the system.
