Chemical Profile

Product Overview

Sodium Hydroxide 20% Technical Grade is a pre-diluted aqueous solution of sodium hydroxide (NaOH) prepared with high-purity deionized water. This 20% concentration provides a convenient, ready-to-use form that eliminates the need for on-site dilution of concentrated stock. Appearance: Clear, slightly viscous pale liquid. This Technical Grade product is manufactured for industrial and commercial applications where high purity is required for consistent performance.

Supplied by Alliance Chemical in sizes ranging from 1 quart to 330-gallon IBC totes, this solution is ideal for operations requiring consistent 20% strength with minimal handling risk compared to higher concentrations.
