MAUMEE, Ohio — Dana has developed a new high-temperature exhaust gasket coating designed to meet the increasing challenges of modern gasoline and diesel engines. The technology, which the company says is the first to withstand temperatures as high as 1,000 degrees Celsius, is currently in production with a large diesel-engine manufacturer.
As automotive and heavy-duty vehicle markets face increasing needs for engine temperature resistance, the Victor Reinz ThermoGlide 1000 high-temperature coating offers a 25 percent improvement over the heat resistance of competitive coatings, according to Dana. In addition, this unique exhaust gasket coating is created using water-based chemistry and an environmentally friendly manufacturing process that produces significantly fewer carbon emissions than traditional volatile organic compound (VOC) based adhesives, the company said.
"We’re excited to introduce this new technology for high-temperature sealing of gasoline and diesel engines," said Rich Kozerski, director of engineering for the Dana technology center in Lisle, Ill. "With ThermoGlide 1000, we’re providing higher temperature resistance, fretting reduction, and improved sealing – all while being environmentally considerate. And most importantly, we continue to deliver high value to our customers."
Dana engineers used a blend of high-temperature lubricants and unique adhesive to create a coating that offers significant improvement in micro-sealing of metal substrates, preventing the escape of gas between the exhaust manifold and cylinder head. By providing heat insulation between mating engine surfaces, heat transfer can be reduced, resulting in increased joint durability and longer service life.
"Through our OEM partnerships, Dana continues to offer customizable solutions that improve the performance and durability of today’s and tomorrow’s vehicles," said Dwayne Matthews, vice president, Dana Power Technologies Group. "By developing green technologies that lessen the overall impact of manufacturing, we’re committed to meeting these needs in an efficient and responsible manner."
