Product overview & key benefits
Potassium 2-ethylhexanoate is the potassium salt of 2-ethylhexanoic acid. In rigid foam it catalyzes the trimerization of isocyanate groups into isocyanurate rings, which gives PIR boards and panels their heat and fire performance; it is normally combined with an amine catalyst to balance cream, gel and rise times. In coatings it is used as a drier.
It is often traded as a solution in a glycol carrier rather than as the pure salt, so the active content and the carrier are the first things to confirm when you compare offers.
Works with amine catalysts
Pairs with tertiary-amine blowing and gel catalysts, so the foam profile can be tuned.

Selection & comparison
Choosing for your foam system
| Your requirement | What usually works |
|---|---|
| PIR boards and panels | Potassium octoate at the active content your system is built on |
| Faster or slower foam profile | Adjust the ratio to your amine catalyst in a trial |
| Replacing an existing catalyst | Send its TDS (active content, carrier); we quote against it |
Packaging & storage
Packaging
Pack size depends on the offered form; drums or IBCs are confirmed with the quotation.
Storage
Keep containers closed in a cool, dry place, protected from moisture and from contamination with acids. Follow the SDS.
From first email to approved supply
Tell us the system
PIR board, panel or spray foam, and the catalyst package you run today.
Compare like for like
Active content and carrier decide the dosage. Compare offers on the same basis before comparing price.
Check reactivity in a cup test
Run a cup or box foam with the sample and compare cream, gel and tack-free times with your current catalyst.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
Tell us your requirement. We match the grade.
Tell us your foam or coating system, the quantity and the destination port. Add your current catalyst grade and we will quote against it.

Potassium 2-Ethylhexanoate FAQ
What is potassium 2-ethylhexanoate used for?
Mainly as a trimerization catalyst in PIR and rigid polyurethane foam. It is also used as a drier in resin coatings.
Is it supplied as a solid or a solution?
Potassium octoate is commonly traded as a solution in a glycol carrier. Tell us the form and active content you use, and we will confirm what we can offer.
Can it replace my current PIR catalyst?
Often, if the active content and carrier match. Send the TDS of your current catalyst and run a cup test with our sample before switching.
Can I get a sample?
Yes. Tell us your foam system and planned test, and we will arrange a sample with the TDS and SDS.
