The move will put the company under the same roof as sister BASF Coatings business Glasurit.
R-M's entire operation - call centre, technical, colour and e-commerce support divisions - are uprooting from Greater London.
“We'll benefit from closer links with BASF and its extensive resources,” says an R-M spokesman. “R-M will be encouraged to continue its work developing innovative solutions for the automotive refinish industry.”
He declines to say whether any redundancies are expected but adds: “R-M wants to keep the team together.”
