About Metal Finishing & Surface Treatment

Acids, cleaners, and specialty chemicals for metal finishing, plating, anodizing, etching, and surface treatment processes.

Frequently Asked Questions

How do I choose chemicals for a metal-finishing process?

Match the chemical, concentration, and grade to the substrate, process stage, equipment, and finish specification. Review the applicable process documentation and test on representative material before production use.

What is the difference between cleaning, etching, and passivation?

Cleaning removes soils and residues, etching changes the surface through controlled chemical action, and passivation supports the formation of a protective surface condition. These processes use different chemistries and controls.

Should I use technical or reagent-grade material?

Use the grade specified by the process or customer requirement. Reagent-grade material may be appropriate where impurity control is critical, while technical-grade material can suit many industrial operations when its specifications meet the process need.

What documentation should a metal-finishing shop review?

Review the Safety Data Sheet, product specification, Certificate of Analysis where required, and the operating or customer specification for the process. Confirm material compatibility with tanks, plumbing, ventilation, and PPE before use.
