Most coating failures I've investigated over four years of industrial quality management were not chemistry failures—they were process failures. Roughly 8 out of 10 field complaints we've examined at Chemours trace back to specification gaps, application errors, or mismatched process conditions rather than a defective chemical product. So if you're evaluating Chemours products (or any comparable coating, for that matter), don't start with "which chemistry is best?" Start with: can we hold the process parameters the coating requires?
Why I can say this with confidence
I'm a quality and brand compliance manager at Chemours, a chemical company that manufactures Teflon fluoropolymer coatings, Ti-Pure titanium dioxide pigments, and specialty chemicals for industrial customers. My job is to review everything before it reaches customers—batch certificates, audit reports, and technical documentation, roughly 200+ items a month. In 2024, I rejected about 3% of first deliveries due to documentation gaps and spec mismatches. I've also conducted more than 40 supplier audits, which gives me a fairly unusual vantage point: I've seen how upstream raw material variability shows up in downstream coating failures, and I've seen how often it doesn't.
When I first started in this role, I assumed the formulation was the most important variable. I thought if the chemical recipe was precise, the coating would perform. That's true, to some extent. But it's kind of like assuming the engine of a car matters more than the maintenance schedule. Both matter. In practice, the maintenance is where most failures happen—and in industrial coatings, the "maintenance" is application discipline.
Does powder coating require heat? Yes—but that's the wrong question
One of the most common questions we get from customers and prospects is: "Does powder coating require heat?" The short answer is yes. Powder coating requires sufficient heat to melt, flow, and cure the resin particles into a continuous film. But that's a bit like saying "food requires cooking"—technically true, not very useful.
The more useful question is: what temperature does the substrate require, for how long, and at what point in the cycle? Most thermoset powder coatings need the substrate itself—the actual metal, not the oven air—to reach roughly 350–420°F (180–215°C) and hold that temperature for 10 to 20 minutes, depending on the specific formulation and required film thickness.
From the outside, powder coating looks like sprayed powder plus an oven—that's it. The reality is that thick cross-sections act as heat sinks. I've seen parts come out of an oven looking perfectly cured—smooth, glossy, fully flowed out—but with a soft film in the center section of thicker extrusions. The oven air was at 400°F, but the heavy aluminum section had only reached 315°F before the part exited. The cure schedule had been written for thin sheet metal, not for the mass of that particular part. On a high-volume production line, that's a full batch failure that looks like a chemistry issue but is actually a thermal profiling issue.
So the answer to "does powder coating require heat" is yes—and the follow-up you should be asking is: how do you verify that the entire part, including the thickest section, reaches the specified substrate temperature for the required dwell time? If your applicator can't answer that question, the coating chemistry is a secondary concern.
Pigment quality is about dispersion, not just color
Another area where I've watched buyers misdiagnose quality is pigment performance. Most people assume pigment quality equals color accuracy. Color is part of it, but in titanium dioxide—which we sell as Ti-Pure and which goes into paints, plastics, inks, and coatings—the properties that determine success are dispersion and particle size distribution.
Here's an unlikely comparison: a Staedtler pigment liner set. Those precision pens, especially the ones with 0.3 mm tips, use pigmented ink where pigment particles must stay uniformly suspended. If dispersion isn't controlled, particles settle or clump, clog the feed channel, and the line quality degrades. The ink can look identical in the bottle; the dispersion behavior is what separates a dry, useless tip from a pen that draws consistently for months.
The same principle applies to industrial coatings. A TiO2 pigment with the right color but poor dispersion shows up as grit in the applied film, reduced gloss, or opacity shifts—sometimes weeks after application. That's why when I qualify any pigment supply, I ask for fineness-of-grind data (typically a Hegman gauge reading) and dispersion test results, not just a color-match report. A pigment can match color and still perform poorly in the field.
The $18,000 asphalt coating lesson
In my first year, I made the classic rookie mistake: assuming a field failure is always a product failure. A Midwest contractor was coating asphalt on a large parking lot with one of our solvent-borne protective coatings—about 40,000 square feet. It blistered and cracked after the first winter. The contractor blamed our product, and I initially believed him.
The site visit changed my mind. The contractor had applied the coating on damp pavement, over unsealed cracks, without a primer, in 42°F weather—well below the minimum application temperature in the technical data sheet. The coating didn't fail. It was installed against its own operating conditions.
The redo cost the contractor roughly $18,000, plus a damaged relationship with their client. And the details were all in the product documentation. Since that project, every contract I've reviewed for an asphalt coating application includes verification steps: surface cleanliness, measured moisture content, ambient and substrate temperature checks, primer requirements, and wet film thickness readings during application. It's not glamorous. It prevents failures that look like chemistry problems but are actually process problems.
Green claims require documents, not vibes
The last thing I'd add to any buying decision is the legal dimension of environmental claims. Per FTC guidelines (ftc.gov), specifically the Green Guides (16 CFR Part 260), claims like "biodegradable," "recycled content," or "low-VOC" must be truthful and substantiated with evidence. They aren't purely descriptive words in B2B marketing; they're claims that need test reports behind them.
A supplier once tried to sell us a "green" pigment concentrate with zero documentation. The pigment itself was probably acceptable. But in an industrial supply chain, a claim without substantiation is a liability waiting for an auditor. I rejected it because the supplier couldn't produce a third-party test report. If a claim appears in marketing, it should trace to a test result in the file.
Where this generalization falls short
To be fair, not every coating failure is a process failure. I've encountered reformulations released before full validation, raw material substitutions that changed cure behavior, and pigment lots that drifted out of spec. Those are legitimate product issues. And in specialized, custom-formulated systems designed for one substrate and one application method, the chemistry is exactly the dominant variable.
But in the broader industrial coating market, the most consistent source of variance is application discipline. That's encouraging: it means many quality problems can be solved with checklists, measurement, and verification—tools that are cheaper and faster than reformulating a product.
So before you reject a coating, or before you assume a premium pigment system is inherently better, look at the process. Check the oven data log. Measure the substrate temperature. Review the applicator's documented procedure against the technical data sheet. In my experience, the coating that fails is usually the one whose application conditions were never validated.
