Milliken & Co. has acquired Keystone Aniline Corp., a global supplier of dyes, pigments, pigment dispersions and polymers, headquartered in Chicago, IL.Both Milliken and Keystone currently provide colorant technologies to the agricultural, plastics, coatings, inks and household, institutional and industrial markets. “This acquisition has far-reaching benefits for everyone involved,” said Russ Rudolph, vice-president, performance colorants and ingredients for Milliken. “Our combined customers win through greater availability of proven colorant technologies and resources that can help them penetrate and grow new markets to gain a competitive advantage. Our suppliers can expect new opportunities that will allow them to play a greater role in serving our expanded organization. From a business perspective, we look forward to accelerating our growth and creating greater value.” Customers of the two companies rarely overlap because until now, they specialized in different product areas. With a core focus on polymeric colorants, Milliken’s performance colorants and ingredients business is known for its proprietary chemistry and ability to synthesize new molecules, while Keystone has strong formulation skills and application development technology. Both firms are privately held, family-owned companies with long histories in the colorants industry: 97 years for Keystone and 152 for Milliken. “By combining our product portfolios and specialized colorant knowledge with Milliken’s solutions and expertise, we create business and market synergies that will drive new global opportunities and better meet the evolving needs of our customers,” said John Andrews, CEO of Keystone. “The resulting organization will possess greater breadth and depth across the board, from research and development to formulation capabilities, quality control and product stewardship. This partnership will be a part of Milliken’s future growth and success.”
