PPG Industries, the world’s largest producer of paints and coatings, announced Monday its $2.3 billion acquisition of Mexican architectural and industrial coatings company Consorcio Comex.

The deal comes some six weeks after Comex launched an arbitration proceeding before the International Chamber of Commerce against The Sherwin-Williams Company over the Cleveland-based paint manufacturer’s alleged failure to push hard enough for its own $2.34 billion buy of Comex.
