Sika Corporation, the U.S. subsidiary of Sika AG, has acquired May National Associates, Inc., a manufacturer of silicone and polyurethane products for sealing and bonding active in the construction, industrial and distribution markets. May National is located in Lakewood, New Jersey with annual sales revenue of approximately $20 million and 60 employees. The acquisition expands Sika Corporation’s position in sealing and bonding by enabling the company to build up its silicone sealants offering particularly in the growing solar and façade markets in North America. After the rollout of its engineered silicones business in Europe in 2004, Sika now has the ability to build a strong silicone footprint in North America and expand its global silicone technology and know-how to this region. May National, founded in 1984, manufactures and markets a full range of silicone, polyurethane, hybrid and acrylic sealants and adhesives. May National will operate as a subsidiary of Sika Corporation and will be managed under the existing May National management team.
