HCP Grade Chromic Acid
The purity of industrial grade chromic acid has generally suffered as domestic and international producers compete for market share. Contaminants such as sulfate, chloride, iron, cooper and even insoluble materials are now common. These contaminants may not be significant in other applications, but they become very important to high quality hard chromium plating. This is especially true when ZERO Discharge Recovery is used.
HCP grade chromic acid is manufactured to our stringent specifications. It is intended for use where quality is of prime importance. In addition, HCP grade chromic acid is a non dusting material that is also very easy to pour and resists caking. It is much more user friendly than the typical flake material is. Each batch is assayed to our stringent standards.
