Audi adopts 'overspray-free painting' method

By CARSIFU | 6 November 2019


SINGAPORE: Audi is now able to apply two different colours in the same painting process using a method known as overspray-free painting.

The new technique is being adopted for the first time for the “edition one” limited-edition models of the A4 Sedan and A5 Coupé, which were updated in 2019.

The customer has the option of choosing a roof in brilliant black. Audi is the first car manufacturer to adopt this environment-friendly technique in series production.

A robot-controlled high-precision instrument measures the laser-brazed seam between the car’s roof and side panel frame. An applicator then applies a black paint specially developed for this method onto the body in strips, with millimeter precision but without spray mist.

Until now, two-colour paint finishes have inevitably involved two painting processes with masking-off beforehand.Overspray-free painting technology revolutionizes this time-consuming and material-intensive process.

Audi has been testing the new painting process intensively since spring 2018 to get it ready for series production.

Since summer 2019, it has been possible to create contrasting paint finishes with a black roof within the series production process.

The A4 Sedan “edition one” with brilliant black roof is available in three colours – terra gray, metallic; Daytona gray, pearl effect and quantum gray.

The A5 Coupé “edition one” is available in the colours quantum gray; Daytona gray, pearl effect and district green, metallic.
