Advanced Quenching Solutions

Signature Collection


Oil-based and water-based quenchants for metal heat treatment processes. These quenchants are designed to improve the quenching process by providing easy cleaning, exceptional oxidation resistance, thermal stability, and consistent performance while minimizing part distortion and breakage.

Video Introduction

Signature Collection



Oil Based

DuBois oil-based quenchants are ideal products for quenching intricately-shaped parts and high-hardenability alloys. They will improve your process by enabling easy cleaning for brighter work, providing exceptional oxidation resis- tance and thermal stability to optimize bath live, minimizing usage and cost with less drag-out, and providing maxi- mum control for predictable performance and consistent, high quality parts.
