About Us

Introduction To Dampney Company, Inc.


Dampney Protective CoatingsSince 1917, Dampney Company, Inc. has manufactured technically advanced, corrosion resistant protective coatings for specialized applications in industries including refining, chemical processing, primary metal, utility, pulp and paper and OEM. Our valued customers include many of the world’s largest corporations.

Dampney’s experience in the field of high performance coatings dates back to 1906 when English researcher John Dampney first produced and marketed Apexior, a unique protective coating capable of preventing corrosion of the internal surfaces of steam boilers, turbines, and auxiliary equipment. Application of Apexior coatings solved many costly corrosion problems for the English power industry. A market for Apexior quickly developed here in the U.S. power industry. To fulfill this growing demand, a group of U.S. investors incorporated The Dampney Company of America in Boston, Massachusetts in 1917, manufacturing and marketing Apexior brand corrosion-resistant coatings under license from the English firm of J. Dampney and Co., Ltd.

Success in this demanding application in the U.S. power industry established Dampney’s reputation as a pioneer in the field of corrosion control and inspired our corporate mission: to develop high-performance protective coatings for special exposures, operating conditions, and end uses. Dampney’s Thurmalox coatings exemplify our commitment to solving industry’s most extreme coating problems. Our Thurmalox line offers solutions for harsh environments including extreme temperatures, corrosion under insulation, high-build corrosion, hot water-side corrosion, and in-service hot equipment applications.


Dampney continues to develop and improve industry’s choice of innovative, right-the-first-time coating systems for protection against hostile environments in atmospheric, immersion, and underground applications. Coating systems are based on a broad range of polymers and pigments resistant to chemicals, extreme heat and weather. Individual coatings and systems are tailored for application to masonry, metal, plastic, and wooden surfaces.


Our primary product lines include:

  • THURMALOX High Temperature Industrial Protective Coatings - for metal structures subjected to high temperatures and corrosive environments.
  • THURMALOX High Temperature Protective Coatings for the OEM Market - for metal products and applications subjected to high temperatures and various environments.
  • EPODUR 100% Solid Novolac Systems - for secondary containment, flooring and concrete restorations.
  • APEXIOR Protective Coatings - for water-side corrosion prevention of steam generating equipment and auxiliaries.
  • DYMACRYL Water Repellent Masonry Stains - for concrete and masonry surfaces.
  • ELASTOID High Build Elastomeric Rubber Coatings.
  • ENDCOR Corrosion Resistant Coatings - for general industrial maintenance.
  • EPODUR High Solids Epoxy Coatings - for long-term, heavy duty protection in aggressive chemical, industrial, and marine environments.

Dampney’s coating application news articles have appeared in leading technical publications, including: American Painting Contractor, Chemical Engineering, Chemical Processing, Journal of Protective Coatings and Linings, Plant Engineering, Plant Services, Gas Industries, and others.

Case histories describing the application of our coating systems under demanding or unusual service conditions are available, as well as a partial client list of engineering and construction firms who specified these products, and refining, chemical processing and utility corporations who use these protective coatings.

Dampney supports the leading technical and trade associations serving the protective coating and paint industries, and is a member of the National Paint and Coatings Association (NPCA), National Association of Corrosion Engineers (NACE), and Steel Structures Painting Council (SSPC).


Continuous modernization and expansion of our Everett, Massachusetts plant gives us the manufacturing flexibility and capacity to meet increased demand for standard and custom coatings, and the ability to produce new and innovative coating systems. Our state-of-the-art manufacturing processes include a computer controlled formula maintenance, batch production, and inventory control system, as well as a computer controlled color matching system.

As a result of our capital investments, we have optimized our cost control, production efficiency and quality assurance programs.


Our well equipped product laboratory enables us to develop new and better coatings to meet industry’s ever changing needs. We adhere to strict manufacturing quality control standards, and with our testing facilities, we help solve customers’ coating and corrosion problems and carefully evaluate existing and new protective coatings, systems and raw materials.


Dampney provides quality coating products tailored to each customer’s requirements, backed by technical service to ensure the coating’s most effective use. Our protective coating technical service entails making a comprehensive survey; analyzing the results and making recommendations; providing laboratory services, surface preparation and application guidance; as well as field inspection and periodic follow-up after project completion. Dampney’s technical service assures maximum protection at the lowest total cost.
