What Thermal Spray Technologies, Inc. does
Thermal Spray Technologies, Inc. (TST) is a Watertown, Wisconsin–based specialty industrial coatings company and division of the employee-owned Fisher Barton Group, founded in 1992. TST provides application-specific thermal spray coating services engineered to extend component life in wear, corrosion, thermal, and electrical-insulation environments. Its product portfolio centers on two registered proprietary processes — FluxFuse® (a flux-bath fusion coating for high-wear agricultural and harvesting components) and Fusionbond® (a precision thermal processing coating for extreme environments) — supplemented by a broader offering of wear-resistant (tungsten carbides, chrome oxides), corrosion-resistant, dielectric, electrically conductive, and thermal barrier coatings, plus discrete products such as the TST-163 iron-based coating. An in-house Technology Center supports metallurgical validation, bond strength testing, and hardness verification, enabling prototype-to-production capability.
The company's customer base spans six verticals: agriculture and food processing, energy and oil & gas, medical, automotive and transportation, aerospace and defense, and industrial manufacturing (construction, mining, pulp and paper, recycling). Application examples range from carbide-coated bolts on agricultural combines to jet engine compressor blades, high-pressure well stimulation plungers, biomedical implants, semiconductor heat sinks, and pipeline infrastructure. The company operates from a single disclosed U.S. facility in Watertown, WI, with no public international footprint.
TST monetizes through professional service fees for coating application, with quote-based pricing driven by component complexity, coating type, and volume. Its go-to-market is a consultative, sales-led direct model: customers engage through a website quote form or phone (920-688-4367), followed by application-specific engineering consultation. Distribution is domestic U.S. only. Marketing support is provided through the Fisher Barton Group's content infrastructure (technical whitepapers, product data sheets, social channels) and is oriented toward engineer-to-engineer demand generation rather than high-volume consumer acquisition.

Thermal Spray Technologies, Inc. product offering
Product offeringCore offering
Thermal Spray Technologies (TST) provides custom thermal spray coating services for industrial components, applying wear-resistant, corrosion-resistant, dielectric, electrically conductive, and thermal barrier coatings to customer-supplied parts ranging from bolts to jet engine components. The company leverages two proprietary processes—FluxFuse® (a flux bath fusion method) and Fusionbond® (a precision thermal processing method)—both of which create chemical fusion bonds rather than mere mechanical interlocking for superior durability.
Product overview
Thermal Spray Technologies (TST), a division of Fisher Barton, is an engineering-driven manufacturing company providing specialized thermal spray coating services and proprietary coating technologies. The product portfolio centers on two flagship proprietary processes—FluxFuse® (a flux bath fusion coating) and FUSIONbond® (advanced thermal processing for extreme environments)—alongside a comprehensive suite of coating services including wear-resistant coatings (tungsten carbides, chrome oxides), corrosion-resistant coatings, dielectric coatings, electrically conductive coatings, and thermal barrier coatings. These coating solutions serve diverse industries including agriculture, energy, oil and gas, medical, automotive, transportation, food processing, aerospace, and defense, addressing wear, corrosion, and thermal challenges through customized surface engineering.
