Automotive Coating Failure Case Expert Witness
A plaintiff in a law suit involving coating failures of a waterborne automotive refinish coating line from a major global paint supplier required an expert witness in coating failures to investigate the claim, provide expert reports, depositions and deliver trial testimony.
Chemical Dynamics conducted extensive research and testing to assess how the failure occurred and to establish its repeatability. Once failure was proven, Chemical Dynamics provided thorough expert witness support.
The plaintiff won the case as the jury found the defendant guilty of fraud and misrepresentation of the product’s performance attributes. The plaintiff was awarded a multimillion dollar judgment.
SITUATION: A global company with multibillion dollar sales required a paint raw material evaluation from a paint expert of the performance and application potential of a new fluoropolymer resin that they developed.
ACTION: Due to the resident coating expertise in fluoropolymer coatings, the supplier contracted Chemical Dynamics to provide an independent evaluation of this new resin chemistry. Our company conducted paint and coatings testing to evaluate the material.
RESULT: Chemical Dynamics completed the evaluation and identified multiple new applications for the fluoropolymer resin chemistry.
Automotive Paint Product Development & Paint Consulting
PROBLEM: A company with multibillion dollar sales to the automotive OEM market required a unique coating for markets around the globe and was unable to locate a paint company with the expertise to develop the requisite performance.
ACTION: They contacted the paint experts at Chemical Dynamics to develop a coating that would meet their performance needs of being REACH compliant, low VOC, low friction with resistant to high heat and automotive chemicals.
RESULT: It a short period of time, Chemical Dynamics was able to develop a product that met all customer requirements.
University Paint Consult/Material Evaluation for Nano-based Additive
SITUATION: A large public university was seeking an independent paint expert opinion of possible applications for a new water based nano-based conductive additive for paint.
ACTION: The university contracted Chemical Dynamics to perform the study.
RESULT: After extensive evaluations, Chemical Dynamics was able to demonstrate that the nano-based material demonstrates the ability to replace heavy metal chrome based pigment for corrosion inhibition purposes. A second utility of the technology was determined to be as a thickener for water born coatings.
A global company with multibillion dollar sales required an independent paint raw material evaluation from a paint expert of the performance and application potential of a new fluoropolymer resin that they had developed.
Due to the resident coating expertise in fluoropolymer coatings, the supplier contracted Chemical Dynamics to provide an independent evaluation of this new resin chemistry. Chemical Dynamics completed the evaluation and identified multiple new applications for the fluoropolymer resin chemistry.
CHALLENGE: A national steel company that supplies coated product to the building industry received multiple complaints that the 20 year warranted coated product they supplied showed severe dirt staining once put into service on commercial and industrial buildings.
ACTION: Chemical Dynamics as an expert paint consultant in paint failure analysis was called upon to inspect several representative building sites where samples were taken, tested and paint and coating failure analysis were conducted.
RESULT: Chemical Dynamics was able to demonstrate that the unexposed coating rapidly degraded when exposed to accelerated weathering resulting in increased susceptibility to dirt staining and loss of hardness. As a result of our analysis and testing the paint company accepted responsibility for the failures saving our client several hundred thousand dollars in claims.

Whether coatings are sold directly to consumers or business to business, UL’s study: Under the Lens: Claiming Green – The influence of green product claims on purchase intent and brand perception reveals that legitimate third-party, certified green claims contribute to the attractiveness of a product and command a higher price because of enhanced brand perception. The survey results are noteworthy, as 70% of Americans say they’re searching for greener products, and 67% of business decision makers indicate sustainability is an important factor when making decisions for their organizations.
Avoiding Misleading Claims
However, many manufacturers misrepresent their products by claiming they are green for the purposes of enhancing sales. In 2012, the Federal Trade Commission revised its Green Guides, the agency’s core set of guidelines to help marketers avoid making misleading environmental claims. The Guides are now more specific and prescriptive, making it easier for the FTC to prosecute “greenwashers.” Accordingly, if a green claim is considered to be deceptive in the eyes of the FTC, there is both a financial and a legal risk.

A national distributor of painted metal roofs encountered peeling paint on several residential and public buildings. The roof coating had a 20 year warranty against peeling provided by the paint supplier, but the paint supplier failed to honor the warranty, citing a defect in the painting process rather than faulty paint. Consequently, this would have resulted in multiple law suits and multimillion dollar claims against our client.
As a paint consultant, Chemical Dynamics inspected multiple sites where peeling paint was evidenced, samples were taken and roof coating analysis and testing completed.
Chemical Dynamics was able to show that the failures were caused from faulty paint formulations that when exposed to the elements resulted in soft coatings that failed adhesion. Accordingly, our client was able shift the responsibility to the paint supplier to pay the claims.
A century old government building, constructed of concrete, was in need of painting. Upon removal of the old paint, a reoccur-able, unpaintable powder continued to resurface on the building. The client had explored this issue with many paint companies and other paint consultants, but none of them could not explain the phenomena.
On short notice, Chemical Dynamics performed an onsite inspection and collected representative samples of the residue. The team performed a paint and coating failure analysis of the soluble components of the residue.
Chemical Dynamics was able to demonstrate that the powder residue is a result of secondary efflorescence of the concrete. Secondary efflorescence is the result of concrete degradation and the migration of water soluble salts to the surface of the concrete. With the proper diagnoses of the problem, Chemical Dynamics was able to recommend corrective action.
The annual cost of steel corrosion is estimated to be over $400 billion in the United States and $2 trillion globally. Corrosion is a process where the metal can be degraded by electrochemical and/or chemical processes. This article will discuss the use of lead- and chrome-free corrosion inhibitive pigments in coatings where corrosion is primarily from electrochemical processes. Accordingly, the correct use of corrosion inhibitive pigments can be of enormous economic value.
Ron Lewarchik is a contributing author to UL Prospector and publishes articles monthly. Please read on for his expert findings on “Understanding Corrosion Inhibitive Pigments”:
Metals desire to be in their most thermodynamically stable state, which, in simplified terms, is the naturally occurring state of matter in its lowest energy state. Metals ordinarily exist naturally as oxides (e.g. iron oxide, aluminum oxide, zinc oxide, because oxides represent their lowest energy state. Corrosion is an electrochemical deterioration of a metal due to the reaction with its environment to transform the metal into its lowest energy state. Oxidation occurs at the anode (positive electrode) and reduction occurs at the cathode (negative electrode). Corrosion is normally accelerated by the presence of water, oxygen and salts (particularly of strong acids).
