Arsenal Capital Partners has acquired Arnco, a polyurethane product manufacturer, from private equity firm Audax Group. It is the first acquisition by Arsenal under the umbrella of Dash Multi-Corp, a platform portfolio company focused on the specialty technologies of polyurethane systems, vinyl plastisols and recycled rubber products. Arnco operates five businesses, including manufacturing divisions for flatproofing systems, polyurethane systems, micro-cellular polyurethane tires, and roofing spray foams and UV protective coatings. Arsenal acquired Dash in December 2012 to create a global polyurethane and specialty materials platform.
