RPM's Carboline and Tremco Subsidiaries Complete Acquisitions

MEDINA, Ohio, Nov. 21 /PRNewswire-FirstCall/ -- RPM International Inc. announced today that its Carboline Company subsidiary has acquired certain intumescent fireproofing assets of Nu-Chem, Inc. and that its Tremco Group subsidiary has acquired Permaquik Corp. The acquired businesses have combined annual revenues of approximately $12 million. Terms were not disclosed.

"These acquisitions typify the types of complementary, bolt-on product lines that can readily and profitably be integrated into our existing operations," said Stephen J. Knoop, RPM's senior vice president - corporate development. "These are great examples of the kinds of synergistic opportunities that RPM and its operating companies intend to continue to pursue going forward."

Carboline is a world leading producer of high-performance coatings and lining systems that protect steel and concrete substrates from corrosion and fire damage. Nu-Chem is an international provider of intumescent fireproofing products for the protection of exposed structural steel, and epoxy intumescents for the petrochemical and offshore oil markets. This business combination is expected to provide added competitive advantage for Carboline in the commercial and industrial segments of the fireproofing market. Both companies are based in St. Louis.

"Carboline now has all the technology to be the leading supplier of fireproofing products for both the architectural and industrial markets - intumescent and cementitious - on a global basis," said Richard M. Wilson, Carboline president.

Tremco Global Sealants, a division of Tremco Group based in Beachwood, Ohio, is the world's leading supplier of sealants and weatherproofing for construction and industrial applications. Permaquik, headquartered in Mississauga, Ontario, is a leading supplier of high-performance, hot-applied waterproofing and green roof systems as well as crystalline waterproofing, epoxies, sealers and expansion joints.

"Permaquik's people, technical expertise and premium products fit well with our strategy of bringing value-added solutions to the construction industry," said Randall Korach, president of Tremco Global Sealants. "Its products and brands have gained tremendous acceptance and recognition particularly in Canada, where Permaquik's hot-applied waterproofing systems are the preferred technology. Permaquik has a large, geographically diversified customer base that will be an important part of growing our North American and international waterproofing business."
