Olin Chemical Superfund Site, Epoxy & Caustic Soda: Top FAQs Answered (2025 Guide)

Your Olin Chemical Questions, Answered

I'm a logistics and procurement specialist at a mid-sized chemical distributor. I've handled hundreds of rush orders in the last five years—including same-day turnarounds for clients whose production line was about to shut down. When you're in a bind, you don't need a brochure. You need answers. Here are the most urgent ones I get about Olin's products and history, based on real calls and real deadlines.

1. What exactly is the Olin Chemical Superfund site, and should I be worried?

I get this one a lot, especially from new clients checking compliance. Olin has been involved in several Superfund sites across the U.S., primarily due to historical operations from decades ago. Per EPA records, Olin is a potentially responsible party (PRP) at sites like the 58-acre Olin Chemical site in Wilmington, Massachusetts, which was listed on the National Priorities List in 2006. The EPA's focus there has been on groundwater contamination from past waste disposal practices.

Does this affect buying their products today? Not directly. Most of these legacy sites are under active remediation. For a current buyer, this is a historical compliance check, not a quality issue with, say, their epoxy resins or caustic soda produced today. I've seen clients walk away unnecessarily over this. My advice? Verify with your legal team, but don't let a decades-old cleanup project stop a critical order. This information was accurate as of Q4 2024. EPA site statuses change, so verify current details at epa.gov/superfund.

2. I have a concrete floor to coat. Is Olin's epoxy paint the right choice?

You're likely looking at Olin's epoxy resin products—they're a major supplier of the raw materials used in high-performance floor coatings. If you're asking about a pre-formulated 'epoxy paint' from their catalog, check the specific product sheet. Olin doesn't typically sell a one-can consumer paint; they sell the resin component that formulators use.

In a pinch for a garage floor? You're probably buying from a brand that uses Olin's EPON™ resins. That's a good sign. These resins are known for strong adhesion and chemical resistance. But here's the catch: the final performance depends on the hardener and the mix ratio. I had a client in March 2024 who ordered a coating system using an Olin-based resin. They poured it without checking the hardener's pot life. It set in 20 minutes—a disaster. Read the technical data sheet. For concrete floors, look for systems rated for foot traffic in 24 hours and full cure in 7 days. If you're in a rush, look for a 'fast-set' hardener, or you'll be waiting.

3. Can I find Olin's entire catalog online? I need a specific MDI grade fast.

Looking for their full catalog? It's not always simple. Olin's product line includes a wide range of chemicals, from caustic soda and chlorine to epoxy resins and MDI (methylene diphenyl diisocyanate). Their online presence is strong for standard products, but for a specific MDI grade for a rush order, you might need to go beyond the public catalog.

Based on my experience, here's the quickest path: call their technical sales line directly. I've done this dozens of times. The public website might list 'MDI' as a category, but it won't show you every variant's inventory. Don't rely on the generic 'olin catalog' for a last-minute order. Call, and have your desired spec sheet (e.g., viscosity, isocyanate content) ready. I've gotten a 5-gallon pail of a niche MDI shipped same-day from one of their terminals by being specific on the phone. Looking back, I should have called first instead of searching the website for an hour. At the time, it seemed faster to browse online. It wasn't.

4. Does epoxy resin stick to parchment paper? I need a non-stick surface for a project.

Yes, it does—mostly. This is a weirdly common question I get from clients doing small art projects or mold making. Epoxy resin does not bond to parchment paper. That's why it's perfect for lining work surfaces or catching drips. The silicone coating on parchment paper creates a release surface. It's also relatively heat-resistant, so it handles the exothermic heat of curing epoxy.

But there's a trap. If you're using a 'resin stone' technique (mixing epoxy with stone or aggregate to cast a countertop), parchment paper can wrinkle. The weight of the stone mix can push it around, leaving texture on your finished piece. For flat pours, it's great. For a textured stone cast? Use a plastic or polypropylene sheet. I learned that the hard way on a $700 countertop pour. Not ideal, but workable.

5. Is 'resin stone' a good choice for a fast countertop fix?

'Resin stone' is a broad term. It usually refers to a mixture of epoxy resin (like Olin's EPON™) with stone aggregates to create a terrazzo-like surface. It looks amazing. But for a fast fix? Probably not.

Time is the killer. The pour is quick, but the curing process—especially for thick pours with stone—can take days. I once managed a job for a restaurant that needed a new countertop in 48 hours. The client wanted 'resin stone.' The full cure time, based on the technical data sheet, was 72 hours. We had to pivot to a polyaspartic coating (which cures in 2 hours) as a temporary fix. If you need it done today, look for a fast-cure epoxy or polyurea system. Resin stone is for when you have a weekend free, or at least a long weekend.

6. What's the best way to get Olin's caustic soda in an emergency?

Olin is a top North American producer of caustic soda (sodium hydroxide). Getting it in a rush requires knowing the supply chain. They ship it in tanker trucks, railcars, or drums (for dry flake). For a small emergency order (e.g., a few 50-lb bags of flake for a pH adjustment), your best bet is a regional distributor that stocks Olin's brand.

Call Olin's customer service and ask for a list of authorized distributors in your area. I did this last quarter when a client's water treatment plant was running low. The first distributor I called said '2-week lead time.' The second one, which Olin specifically recommended, had it in stock for next-day pickup. The difference was just one phone call. My advice? Don't rely on your usual supplier if they aren't an Olin-authorized channel for caustic soda. They may not have priority access. Verify current pricing and availability directly—as of January 2025, caustic soda prices were volatile.

7. How do I handle an Olin product that arrives with a damaged seal or drum?

This happened to me in November 2023. A 55-gallon drum of Olin's toluene diisocyanate arrived with a dented top and a leaking bung. First, do not touch the liquid if it's leaking. Isocyanates are serious. Second, document everything. Take photos of the drum, the leak, and the shipping label. Third, call Olin's customer service immediately. They have a specific process for hazardous material claims.

Here's the protocol I follow now: I immediately isolate the drum in a bunded area. Then I call Olin's 24/7 emergency line (not the sales desk). They'll ask for the lot number and the bill of lading. They arranged for a hazmat pickup within 4 hours in my case. Don't accept a damaged drum on delivery. Refuse the shipment if you can see the damage. If you sign for it, the claim becomes harder. That's my golden rule after that November debacle.
