Engelhard Smog-Eating Technology Surpasses Two-Million-Vehicle Mark

ISELIN, N.J.--June 30, 2004--Engelhard technology that turns cars into smog-eating machines is being featured on two new car models, pushing the total number of vehicles now equipped with the unique technology to more than two million worldwide.

The latest models to incorporate Engelhard PremAir(R) ozone-destruction catalysts are Volvo's new five-cylinder-engine S40 sedans and V50 station wagons. The environmental technology is featured on most Volvo models sold worldwide as well as on select models produced by other European and Asian auto-makers.

When coated on a car's radiator, PremAir destroys up to 75% of harmful, ground-level ozone in the air that passes across it. Ground-level ozone is the main component of smog and is directly linked to respiratory problems and damage to vegetation.

PremAir provides automakers with another tool in their efforts to meet increasingly stringent environmental regulations.

"PremAir is truly unique because it is the only technology being employed on vehicles that destroys ozone already in the ambient air regardless of the source," said Dave Kuzy, commercial manager, environmental technologies at Engelhard. "We're pleased to continue our long collaboration with Volvo in the development and commercialization of technologies that help preserve the environment."

In the 1970s, Volvo and Engelhard first commercialized the modern three-way catalytic converter now widely used around the world. In 1998, the two companies teamed up to introduce PremAir, which meets Volvo's high standards for ozone conversion rates, durability, cost effectiveness and negligible impact on radiator performance.
