New York private equity firm Arsenal Capital Partners is acquiring Arnco, a company that supplies polyurethane products.

Arnco will be added to Dash Multi-Corp., a St. Louis, Mo.-based company that develops vinyl and recycled rubber products. Arsenal Capital Partners bought Dash in December 2012. The firm expects to make several more add-on acquisitions to Dash. Terms of the deal were not disclosed.

The South Gate, Calif.-based target operates through five business units: Arnco Tire Flatproofing, Arnco Performance Polymers, Carefree Tire, Arnco Construction Products and Arnco Europe. The company has manufacturing operations in South Gate, Berea, Ohio, Manchester, England and Jianxing City, China.

Arsenal invested in IGM Resins, Plasticolors Inc., Evonik’s colorants business and Fluoro-Seal Holdings in 2012. The firm closed Arsenal Capital Fund III LP with $875 million in committed capital in April. Arsenal focuses on investing in specialty industrial and health care companies.
