In response to the trend for customisation of vehicles, automobile manufacturers are enriching their colour palettes and developing what are known as high chroma colours. Originally formulated in the tri-coat system using a basecoat and a coloured clearcoat, these colours require particular skills and are making repairs increasingly complex for body shops. For both easier implementation and guaranteed high-quality repairs, R-M is sharing its colour-matching expertise by developing a specific procedure that simplifies the steps while guaranteeing perfect colour reproduction.

R-M’s technical expertise improves productivity

Focused on the technical and economic success of its customers, R-M relies on its colour-matching skills to tailor its repair processes to vehicle fleet advances and the requirements of body shops. Repairs on vehicles with tri-coat (high chroma) colours are now becoming more and more frequent. The advantage of these technologies is that they can be used to produce totally new colours, although they do make colour matching more complex. With this in mind, the challenge for the body shop is to maintain the quality of its repairs without compromising the productivity and profitability of its workshop operations.

It was on this premise that R-M, BASF’s Automotive Refinish premium brand, developed a wet-on-wet blending technique tailored to the specific characteristics of tri-coat colours. By reducing the complete colour-blending process to three steps, it is now possible to work on small areas and even to perform a wet blend on a single part.

This type of repair, which until now had rarely been seen as an option, is now possible. It makes the work simpler; fewer steps are involved; and there is less risk of a colour discrepancy during implementation. These are three advantages that bodywork painters should exploit in order to overcome the associated technical challenges. No other products are required in order to achieve perfect results. This new process can be used for all colours of this type and, by extension, for the entire existing colour palette.

“The system guarantees optimal colour reproduction and high-quality results on small areas while also optimizing repair times. But this single procedure requires special technical know-how; hence why training modules specifically for repairs on high chroma colours were created,” says Thierry Leclerc, R-M’s Technical Manager for Western Europe.
