Who Buys This

Alkaline electrolyzer operators and hydrogen producers, battery and electrolyte formulators, and industrial cleaning and gas-treatment users. Potassium hydroxide is specified over sodium hydroxide here because the potassium ion's smaller hydration radius gives higher ionic conductivity at the same concentration.

Purity / Grade Guide

Technical grade is the working standard for electrolyte and cleaning duty. Step up to 45% if you would rather dilute on site, or down to 25% for general neutralization.

Pack Sizes

Quarts and 1-gallon jugs suit bench work and small-batch prep; 5- and 15-gallon containers cover pilot runs; 55-gallon drums and 275/330-gallon totes feed production dosing and continuous systems.

Small Packs: UPS Ground nationwide for pints, quarts, and gallons.

LTL / FTL: ABF, SEFL, Saia, XPO, and partner carriers for pails, drums, totes, and full truckloads.

Support: Email or call for freight options, hazardous-material routing, and lead-time confirmation.

Description
Product Documents
Chemical Profile

Potassium hydroxide 30% solution — caustic potash at the concentration alkaline electrolysis actually runs on. Supplied ready to use as a clear, colorless liquid at 30% w/w, with no dissolution step and no exotherm to manage on site.

Industrial alkaline electrolyzers typically operate on 20–30% KOH, and 25–30% is where conductivity is best without pushing viscosity or cell-component corrosion. Potassium hydroxide is preferred over sodium hydroxide for this duty because the potassium ion carries a smaller hydration radius, giving higher ionic conductivity at the same concentration.

Typical applications

Alkaline water electrolysis and hydrogen generation
Alkaline battery electrolyte preparation
Industrial cleaning and degreasing
pH adjustment and alkalinity control
Neutralization of acidic process streams
CO2 scrubbing and gas treatment
