Longevity Coatings is a thermal spray coating service firm with offices and production facilities in Allentown,PA, about a mile west of the Lehigh Valley International Airport.
The company’s primary service area is Lehigh Valley (PA) and the Pennsylvania-New York-New Jersey area. Specializing in application of thermal spray coatings to wear and machine parts used in a wide variety of industrial applications. The coatings, usually carbide, ceramics and other metals are used to protect machine parts from wear, abrasion and corrosion and extend their useful life.
The company employs computer-programmed equipment to precisely control the applications of protective coatings through various thermal spray coating processes. These include HVOF (high velocity oxygen fuel), plasma coatings, twin wire arc and combustion flame spraying and fused coatings (diffusion bonded) processes.
Originally located in Pen Argyl, PA, Longevity quickly outgrew its start-up facility. This spurred the relocation to its current two-acre site at 6047 Adams Lane in Allentown PA, in 2007.
The company’s growth was spurred, in large part, by breakthroughs in the development. In both coatings materials and coating application processes. In response to these advances, design engineers have increasingly specified hardface coatings for new machine parts to extend the lifespan of production machinery and reduce downtime. This has led to unprecedented growth for the thermal spray coating industry in general and for Longevity Coatings in particular, according to Mark A. Purington, founder and manager of the company.
The facility, Which occupies 13,000 square feet in two single-story buildings, is equipped to handle completely manufactured, coated and ground components. This includes parts in excess of 40’ long at a diameter of 50”. The facility also is equipped with an outside tailgate loading dock and three drive-in loading doors.
Purington has been active in the spray coatings business for more than 30 years. While still a business major at Penn State University, he managed his father’s nearby thermal spray coatings plant. He formed Longevity Coatings in 2005.
