Rohm And Haas Begins Operations In Mexico

Philadelphia-based Rohm and Haas Co., a supplier of solutions for the specialty materials industry,
has commenced production of emulsion polymers and polyacrylates at its new high-technology plant in
Querétaro, Mexico.

Rohm and Haas will produce products for the building and construction, industrial, adhesives
and household goods industries at the plant, which is the first in Latin America to operate under
the company’s 21st Century manufacturing principles. The company’s main objective in opening the
plant is to increase its presence in Mexico, the Andean Countries, Central America and the
Caribbean; and it expects growth between 10 and 15 percent in the Latin American region.

“With this action in Querétaro, we welcome this new production and distribution platform for
our products,” said Mauro Trevisani, Mexico country manager, Rohm and Haas. “This gives the best
attention to our customers in Mexico and Latin America. At the same time we will satisfy customer
needs more efficiently by transferring the production we had in Apizaco plant to Querétaro.”
