KOH
- Potassium Hydroxide -

Potassium Hydroxide (KOH) ia a highly caustic and reactive chemical, commonly used in applications such as soap production, biodiesel manufacturing, fertilizers, batteries, and chemical synthesis. One of its most relevant modern uses is as an electrolyte in electrolyzers for hydrogen production, where its strong alkaline properties allow efficient water electrolysis.

In these processes, KOH is typically handled in aqueous solution, where its high alkalinity brings significant challenges: severe corrosion risks, chemical burns, stress-cracking of incompatible alloys, and degradation of sealing elements. When combined with pressurized systems, the risks of leakage and accelerated material wear increase considerably.
