Longevity Coatings is a thermal spray coating company with offices and production facilities in Allentown, PA, about a mile west of Lehigh Valley International Airport. We apply thermal spray coatings, usually carbides, ceramics and other metals, to wear and machine parts used across industry, protecting them from wear, abrasion and corrosion and extending their useful life.
Our primary service area is the Lehigh Valley and the Pennsylvania–New York–New Jersey region.
Our history
Founder Mark A. Purington has been in the thermal spray business for more than 30 years. While still a business major at Penn State University, he managed his father’s nearby thermal spray coating plant. He formed Longevity Coatings in 2005.
The company started in Pen Argyl, PA, and quickly outgrew its first facility. In 2007 we moved to our current two-acre site at 6047 Adams Lane in Allentown.
Our growth has been driven by advances in both coating materials and application processes. Design engineers increasingly specify hardface coatings on new machine parts to extend the life of production machinery and reduce downtime.
Our facility
Our facility is equipped to deliver completely manufactured, coated and ground components, with an outside tailgate loading dock and three drive-in loading doors. We also coat large parts, inside and out.
Computer-programmed equipment precisely controls every coating application, across HVOF, HVAF, plasma, twin-wire arc and combustion flame spray, and fused (diffusion-bonded) coatings. We hold suppliers of ceramic and tungsten carbide powders to our own specifications and require certification on every shipment.
Quality
Our quality management system conforms to ISO 9001:2015.
