When I was on a service call last quarter to a mid-sized manufacturing plant in the Midwest, the plant engineer pulled me aside after our routine check. “We’ve been struggling with these process chemicals we’ve been mixing in-house,” he said, pointing to a worn stainless steel tank in their prep area. “Last month, half a batch corroded through before we even got it to the next step, and we’re not sure if it’s the chemical mix or the tank itself.” That conversation stuck with me, because it’s the kind of question I get every week from clients across industries: how do the other process chemicals we supply actually interact with the materials they come into contact with—and how do we make sure those interactions don’t derail their operations? Other Process Chemicals
For context, when we talk about “other process chemicals,” we’re not referring to the big-ticket items like solvents or industrial cleaners that most people associate with chemical manufacturing. These are the specialty, often understated, chemicals that act as the quiet backbone of so many production lines: anti-foaming agents used in food and beverage processing to prevent excess foam during mixing, corrosion inhibitors that protect metal pipes from rust, pH adjusters that keep reactions stable, and dispersants that keep pigments from clumping in paint or plastic manufacturing. Each of these is formulated for a specific purpose, and their performance lives or dies on how well they play (or don’t) with the materials around them.
Let’s start with the most common material we work with: carbon steel, which is the go-to for piping, tanks, and structural components in 60% of industrial facilities. Carbon steel’s main vulnerability is oxidation, or rust, which happens when iron reacts with oxygen and moisture—but process chemicals can accelerate or slow this reaction dramatically. Last year, we had a client in the agricultural chemical sector who was using an unformulated pH adjuster in their carbon steel storage tanks. What they didn’t realize was that the adjuster’s high alkalinity, combined with small amounts of residual hydrogen sulfide from their raw material, created a mild galvanic cell effect on the steel’s surface. Over six months, that caused pitting corrosion—small, deep holes that weren’t visible during routine inspections, but eventually led to a leak that cost them $120,000 in lost product and downtime. The fix? Switching to our specialty corrosion-inhibiting pH adjuster, which forms a thin, invisible molecular layer on the steel’s surface that blocks the reaction between the steel and the chemical mix. It’s not that the pH adjuster itself was bad—it just interacted poorly with carbon steel’s porous, iron-rich surface, and the client didn’t have the data to spot that mismatch.
Then there’s stainless steel, the second most common material, prized for its resistance to corrosion but not impervious to interaction with specialty chemicals. Most stainless steel grades (like 304 and 316) rely on a chromium oxide layer that forms on the surface to protect against damage. But certain process chemicals can break that layer down, a phenomenon called intergranular corrosion. For example, in the semiconductor manufacturing space, clients use high-purity dispersants to keep silicon wafers free of particulates. Those dispersants, if formulated with chloride compounds, can etch the chromium oxide layer on 304 stainless steel, leading to micro-cracks that contaminate batches of wafers. We recently worked with a semiconductor client who was seeing a 12% reject rate on their wafers, and after testing, we found the chloride in their previous dispersant was reacting with their stainless steel transfer lines. Our solution? A chloride-free dispersant formulated for 316L stainless steel, which has a higher molybdenum content that makes it more resistant to chloride-induced corrosion. The reject rate dropped to under 1% within two months. It’s a small detail, but the interaction between a chemical’s additive and a material’s alloy composition is make-or-break for industries where even one contaminated part can cost thousands.
Not all materials we work with are metal, of course. Plastic and polymer components are ubiquitous in pumps, gaskets, and processing liners, and their interaction with process chemicals is a whole different set of challenges. I remember a food processing client who was using silicone gaskets in their mixing vessels, paired with our anti-foaming agent for fruit juice production. Within three months, the gaskets were cracking and leaking. At first, we thought the anti-foaming agent was at fault, but when we ran compatibility tests, we found it was the fruit juice’s high acid content, combined with the anti-foaming agent’s silicone base, that caused chemical degradation in the silicone. Silicone has a low resistance to polar solvents and acids, so the juice’s acid broke down the polymer’s molecular bonds, leading to brittleness. We switched the client to a polypropylene gasket, which has a higher resistance to both acids and the non-silicone anti-foaming agent we reformulated for their line. The gaskets lasted 18 months with no issues, a huge improvement from the three months they were getting before. This is another key point: plastic and polymer interactions are about swelling, softening, or hardening—things that aren’t visible until a gasket fails or a plastic line cracks mid-production. That’s why we run 14-day accelerated compatibility tests for every client’s material and chemical combination, something many smaller suppliers skip to save time.
Glass and ceramic materials are less common for large-scale processing, but they’re critical in specialty chemical and pharmaceutical manufacturing, where purity is non-negotiable. Glass is generally inert, but certain process chemicals can cause etching, especially over extended contact. For example, alkaline anti-foaming agents used in biotech manufacturing can slowly etch the inner surface of borosilicate glass bioreactors, leaching small amounts of silicon into the chemical mix. That leachate can throw off the pH of sensitive biological reactions, ruining cell culture batches. We worked with a biotech startup last year that was seeing inconsistent cell growth in their 100L glass bioreactors, and after testing, we confirmed the alkaline anti-foaming agent was etching the glass. We reformulated the agent to be slightly more neutral at working pH levels, and recommended applying a thin glass coating (a common, low-cost step we don’t charge extra for) that blocked the etching. The cell growth consistency went from a R-squared value of 0.72 to 0.94, which is a game-changer for a company trying to get a new therapy to market.
A common misconception I hear from clients is that more “stable” chemicals will interact well with all materials, but that’s not true. Take rubber, for example—used in hoses, O-rings, and seals across every industry. Nitrile rubber is resistant to oils and mild acids, but it breaks down quickly when exposed to strong oxidizers like some corrosion inhibitors. EPDM rubber works well for water-based systems, but fails when exposed to many solvents. We had a client in the textile industry who was using nitrile hoses to transfer our dispersant, which has a small amount of hydrogen peroxide as a stabilizer. Within two months, the hoses were swelling and splitting, causing downtime that cost them $50,000 a week. We switched them to EPDM hoses, which are resistant to low concentrations of hydrogen peroxide, and the issue was resolved. The key here is that material compatibility isn’t a one-size-fits-all equation—it’s about matching the chemical’s functional components to the material’s inherent properties.
So how does a specialty chemical supplier like us avoid these mismatches, and why does that matter for our clients? For starters, we don’t just sell chemicals—we offer compatibility testing as a core part of our service. Every client we work with gets a free, no-obligation compatibility assessment, where we test our chemical against their specific equipment materials, their operating temperature ranges, and their process conditions. We also keep a database of over 2,000 material-chemical combinations, built from 15 years of working with clients across 12 industries, so we can often flag potential issues before a client even places an order.
Last year, we rolled out a new line of anti-foaming agents for the pulp and paper industry, which has very specific requirements for both metal and concrete processing equipment. Concrete is another material that’s often overlooked, but it’s extremely common in paper mill basins and storage pits. The alkaline process chemicals used in pulp bleaching can leach calcium from concrete, leading to concrete degradation over time. Our new anti-foaming agent was formulated to have a neutral residual pH, and we added small amounts of calcium-stabilizing additives that reduce concrete leaching. For a client in Canada with a 20-year-old concrete mixing basin, that meant they didn’t have to line the basin with an expensive polymer coating, saving them over $200,000 upfront.
I also want to talk about something that’s not talked about enough: long-term vs. short-term interactions. A chemical that works for a single batch run might fail over months or years of continuous use. For example, in oil and gas drilling, corrosion inhibitors are pumped into pipelines, but over time, repeated exposure to the inhibitor and reservoir water can cause micro-seeding in some metal alloys, leading to cracking. We developed a modified version of our corrosion inhibitor for a drilling client in the Permian Basin that has a slower release rate, so it doesn’t build up on the pipe’s surface and cause micro-seeding, even after two years of continuous use. That’s the kind of detail that comes from working closely with clients, not just selling a product off a shelf.
At the end of the day, every client’s biggest goal is to keep their production running smoothly, avoid downtime, and deliver a high-quality product. The interactions between our process chemicals and their materials might seem like a small, technical detail, but it’s often the difference between a $10,000 batch that goes right and a $100,000 mistake that shuts down an entire line. We’ve seen it too many times: a client buys a cheap chemical from a supplier that doesn’t test for compatibility, and ends up with corrosion, leaks, rejected batches, and lost revenue. Our job as a specialty process chemical supplier isn’t just to provide the chemical you asked for—it’s to make sure that chemical works with your specific equipment, your processes, and your long-term goals.
