DuPont and the Tony & Hasu Corporation have inked a strategic alliance agreement to start comprehensive cooperation in architectural coatings in China. The agreement initially will focus on promoting building profile materials and coatings for doors and windows. A PVC automatic production line for building profile materials and color paint sprays will be located at Tony & Hasu’s subsidiary, Shandong Hasu. The line will use DuPont’s automatic spraying technology, which meets the demand for large-scale production, according to DuPont officials.
