Praxair Surface Technologies

The Concentrated Acetylene Company (later known as Prest-O-Lite) was formed in 1904 and built a factory in Indianapolis in 1912, focusing on creating headlights for the world’s first automobiles. Our global capabilities expanded as we developed our unique quality control process, which ensures uniformity and repeatability regardless of the component or continent. We expanded our product and service offerings by acquiring SermeTel™, SermaLoy™, SermaGard®, SermAlcote®, SermaLon™ and other high-performance slurries. Our newest advances—like suspension plasma spray and next-generation coatings and powders—provide greater safety, durability and efficiency to many industries, including oil and gas exploration, alternative energies, aviation and industrial power generation. Our legacy of innovation continues as we experiment with advanced additive manufacturing powders, environmentally sustainable coatings and other products, and innovative new processes, such as rapid prototyping technologies and advanced application methods. Our commitment to constant improvement will keep Praxair Surface Technologies on the leading edge of the industry for decades to come.
