Metallic
debris from nearby blasting operations became embedded in
fresh paint, which subsequently led to rust staining when
the tank was eventually put in service.
| Analysis
by SEM-EDS of the back side of a coating which
peeled from aluminum revealed that the problem was
due to the formation of corrosion (aluminum oxide)
aggravated by salt (sodium chloride) contamination
beneath the coating.

Because our paint testing experience spans so many different industries, Weldon Laboratories is familiar with nearly all of the coating types in use today. We have worked on projects involving alkyds, epoxies, urethanes, moisture-cured urethanes, polyureas, polyaspartics, vinyls, acrylics, polyesters, coal tars, coal tar epoxies, inorganic and organic zinc-rich primers, fluorinated coatings, polysiloxanes, lacquers, conversion varnishes, phenolics, powder coatings, and more.
Although our paint laboratory is well equipped to do the routine ASTM, NACE, and military specification testing often required in the coatings industry, we are much more than just a paint testing laboratory. We provide coatings consulting and paint failure analysis services, and can even help design testing programs to evaluate new coating products.
Dwight Weldon, President of Weldon Laboratories, has over 25 years of experience in the paint and coatings industry. He is an SSPC Certified Protective Coatings Specialist (#407-312-0071) and holds B.S. and M.S. degrees in chemistry from the University of Michigan and Michigan Technological University. In addition to routine physical and analytical testing of coatings, Mr. Weldon has worked on well over a thousand paint failure analysis projects involving nearly all types of paints and coatings in a variety of industrial and architectural applications. He has presented numerous lectures and workshops, and is the author of the well-known “Failure Analysis of Paints and Coatings”, published by John Wiley & Sons.
