1 InspectThis! Fall 2014 Supplement to CoatingsPro Magazine Fall 2014 The Role of the Coating Inspector By Malcolm McNeil, CIP Committee Chair T h ere has been much discussion in the coatings industry as to what the role of the coating inspector is. The definition will vary in different countries around the world. The definition will also vary within any country depending on whom you ask. The NACE International Coating Inspector Program (CIP) defines the role of the coatings inspector as that of a “quality control technician” who is primarily responsible for observing and reporting the technical aspects of a coating project and its conformance or deviation from the project specification. CIP goes on to say that the general duties of the inspector are: •Observe •Test • Verify conformance to specification (with documentation) •Report We hear the terms “quality control” and “quality assurance” in explaining the role of the inspector. Often these terms are used interchangeably, but do they mean the same thing? Let’s take a look and see if we can get some clarification. Webster’s Dictionary defines “quality” as “character with respect to fineness or grade of excellence.” One of the definitions in the dictionary for “control” is “to test and verify.” We find the definition of “assurance” as “a positive declaration intended to give confidence.” Based upon these definitions we could say that the coating inspector does some of both quality control (for example, taking dry film thickness measurements) and quality assurance (for example, reporting that the work is in compliance with the specification). We are taught that it is the responsibility of the coating inspector to observe the work and perform required tests to determine whether or not the contractor’s work is in compliance with the specification. Some people will call this “quality control” and some people will call it “quality assurance.” Whatever we call it, the coating inspector must be clear on what his or her responsibilities and authority are for every project. If this is not spelled out in the specification, the coating inspector should ask for a clarification at the pre-job conference. If there is no pre-job conference, the coating inspector should get clarification from whomever they are reporting to on the project. Everyone on the project should be aware of what the coating inspector’s responsibilities and authority are. As pointed out previously, these can vary depending on the geographical location of the project. In some countries the coating inspector is expected to direct the workers. Many Everyone on the project should be aware of what the coating inspector’s responsibilities and authority are. consider this to be project management rather than quality control or quality assurance. In summary, the role of the coating inspector should be defined on each individual project. It is critical that the coating inspector accept only work for which he or she has the required training and qualifications to perform. As inspectors we must understand clearly what our responsibilities and authority are for each project. Each of us who are NACE certified signed an attestation when we took our exams. It is a good idea to review that attestation from time to time to keep it fresh in our minds.! IN THIS ISSUE...

Fall 2014 Coating Failures—A Coating Supplier’s Perspective By Russell Spotten, Corrosion Probe, Inc. A s a 30-year veteran of the coatings industry, I have seen just about everything that could go wrong on a project. These problems have been caused by any number of factors, including contractor error, bad specifications, improper product selection, Mother Nature, etc. This article will discuss a few incidents where the manufacturer was the primary cause for a problem project. Rework One of the persistent problems confronting coating manufacturers is managing inventory. Raw material and finished goods inventories have a tendency to balloon out of control if not actively managed. Ideally, most of the finished goods in the system are salable, and this inventory moves over time. There is a certain amount of product, however, that never gets sold and must be disposed of. Reasons for this non-moving stock include obsolete products, stock exceeding its shelf life, mistinted paint, returned or damaged goods, and just plain bad production batches that can never be sold. A key inventory management process is “rework.” Manufacturers try very hard not to dispose of paint. It is expensive to dispose of paint properly and lawfully. From a financial viewpoint, it is bad enough that the manufacturer has sunk all the costs into the original product, and then has to suffer additional costs to dispose of the paint. Rework of this unsalable material into new batches of paint is one way to get rid of this “waste” as well as generate some sales revenue in the process. Rework is not always a bad thing and, when done properly, can reduce the amount of hazardous waste. Many large paint companies take pride in their sustainable manufacturing processes, which strive to eliminate or minimize the hazardous waste stream. Finished batches of paint where rework has been used are run through all of the quality control (QC) processes and must pass all performance tests required for the original formulas. Therefore, from the customer’s point of view, there should be no difference in batches produced with new raw materials or with rework materials added. Rework during paint manufacturing, however, can sometimes lead to very interesting problems. Black is Not a Color As a sales manager for a large coating company, I had handled many customer calls and was always anxious to be of help—especially with complaints. On one occasion, a complaint call came to my desk that had me completely stumped. The owner of a barge coating company, and a longtime valued customer, called to say Fall 2014 that the black epoxy coating they had just purchased from us was not, in fact, black. Worse than that, his crews had just finished spraying a complete barge exterior hull with our product, and the barge owner was very unhappy with the unsightly, ruddy brownish-black finish color. How could it be possible that our black epoxy was not black? Surely the painter must have done something on his end to have caused such a problem, or perhaps there was some other environmental issue that caused the complaint. Or, maybe it was a mislabeled batch of epoxy of a different color. While mislabeling is rare, it can happen. I knew from experience that all of our black products were manufactured with black pigments, and color controls were a part of each and every batch ticket and QC tests. Or so I thought. When I discussed this complaint with the plant QC manager, he just stared at me for a few moments and then said, “There is no color control requirement in this product’s formula or batch ticket.” My initial thought was, so what. Black is always black, isn’t it? Or at least it should be close to black. But no, the QC manager was steadfast in his stance that this formula for “black” epoxy was not color controlled. I guess that in his view, this black epoxy could be almost any color since there were no QC tests to tell him otherwise. Rework was the culprit in this case. Upon further investigation, the only color for this epoxy coating that did not have color controls as part of the batch ticket was black. Therefore, if any rework of this same formula epoxy coating needed to be disposed of, it was added to a fresh batch of black epoxy. The resultant color of these batches with rework was usually “mostly” black, but depending on the quantity and color of rework added, this product would sometimes turn out to be a ruddy greyish brownish color, which was nowhere near black. I learned an expensive lesson from this complaint, and a complete review of color controls and QC tests was conducted for all products. Not All Polyurethanes Are Created Equal Those who follow the paint and coatings industry closely know that merger and acquisition activity has increased dramatically over the last 25 years. In the early 1990s, I witnessed one of the larger acquisitions in the North American coatings market, which saw both the combining of InspectThis! 3 some very large businesses, as well as the paint the senior management had agreed to divesting of others.

A couple of the more optimistic chemists even thought that mixing these two chemistries might just produce a product with even longer color and gloss retention than the standard formula. Trials were run at the lab and plant, an acceptable percentage of this old PUR that could be added into new batches was calculated, and the disposal work began in earnest. What happened afterward was a big lesson in how rework and hasty lab work Fall 2014 can sometimes yield disastrous results. Soon after some of these finished products were sold and applied on industrial projects, complaints were all of the same nature— the PUR film showed excessive bubbling, fisheyes, and cratering when curing, and in some cases looked like it wanted to crawl from the surface. In the ensuing investigation, it was discovered that something had been overlooked by the lab when developing a formula for the rework. The investigation revealed that the trial samples of this rework PUR were never applied over an epoxy intermediate coat, which is most commonly used in paint systems. No one ever thought to apply this as a system over the primers that are typically sold. Instead, the formulas were tested for viscosity, dry time, gloss, grind, etc. by using standard QC test methods in the lab for a batch of paint. This included viscosity measurements, drawdowns with a linnetta bar, color and gloss checks, etc. As it turns out, the “revised” PUR topcoat was not very compatible with the epoxy primer, which led to the rash of complaints. Another issue with this rework plan was the quantity added to a particular batch. Depending upon the color of the batch of paint being produced, there was a variation in the amount of old PUR added. Some PUR colors received more rework, some less. Therefore, the complaints from the field were not consistent, making each case that much more difficult to trace and pinpoint the cause of the problem. As a result, thousands of gallons of PUR were recalled as unsalable. This unusable product now truly needed to be disposed of at an extreme cost. Claims for rework were in the tens of thousands of dollars, and the reputation of this otherwise solid industrial paint manufacturer was tarnished.

Fall 2014 InspectThis! 5 Inspection and Training: Variables Involved in Quality Control This article is an excerpt from C.G. Munger’s Corrosion Prevention by Protective Coatings, now in its third revision by Associate Author Louis D. Vincent, Ph.D. The third edition is available from the NACE Store at www.nace.org. T here are so many variables involved in coating applications that it may seem surprising that any good applications are ever obtained. First of all, environmental conditions vary from hot, dry weather to cold, humid weather. Coupled with these outside variables are the variables inherent in the material itself, which can range from a fast-drying vinyl to a slow-curing polyamide epoxy. There are also variables associated with those doing the application work. For instance, one person may be proficient at applying one type of coating, while another may be much better at applying a second type of material. Inspection to provide in-process quality control is the only way in which variables such as these can be properly controlled. Another possible variable is the degree of understanding regarding the specifications or the design engineer’s coating requirements. In many cases, the general character and physical properties of a coating are not fully recognized by engineers, architects, contractors, and, more often than not, the actual owners. Many of these people regard a high-performance coating as no more than an average type of paint. While it is true that there may be no difference in the application equipment used, there is quite a difference in the handling and processing of the various coating materials. A coating is a highly complex material. It is formulated from as many as 20 different materials mixed (or in some cases reacted) together, yet the end product is a very thin film of only a few microns or thousandths of an inch thickness. As such, it must adhere to the surface; protect the surface from penetration or corrosion; and resist abrasion, high humidity, weather, water, chemicals, precipitated salts, or actual immersion in corrosive or aggressive solutions. In all cases, the coating is a thin film separating two reactive materials. Understanding the complex nature of coatings emphasizes the need for good specifications and inspection procedures. Inadequate specifications also represent a variable, as discussed in the previous chapter on specifications. Many specifications are so inadequate as to be nearly useless in obtaining the desired coating. This is often caused by a lack of communication. However, poor specifications are often caused by engineers using antiquated specifications that are completely improper for the job at hand. Selection of the lowest bid, irrespective of the quality of the bid, also presents a difficulty as far as quality control is concerned. Even though the bid may be a legitimate one, once problems begin to occur, there is the inevitable trend toward a reduction in quality to make up for the losses caused by various problems. Even small variations in the application process can make substantial differences in the end product. Efforts to reduce labor costs through quick applications inevitably lead to a lack of proper care during the application, which further deteriorates the quality that is necessary for the use of high-performance coatings. Another difficulty from a quality standpoint is that too often the superintendents, managers, and even owners fail to understand the importance of corrosion control and the role that coatings play in preventing corrosion. Because painting is such a commonplace activity, supervisors and managers often do not realize that it is the greatest single factor in the cost of maintaining corrosion-free industrial structures. Thus, little attention may be paid to proper inspection of the final job. While this situation is not true in every case, it is common enough to be considered a serious difficulty with regard to coating quality. ! Coating quality depends on level of inspection. The inspector should understand application characteristics of the coating. 6 InspectThis!
