PBTC sodium salt

PBTC sodium salt (CAS 40372-66-5) is the neutralized salt form of 2-phosphonobutane-1,2,4-tricarboxylic acid, supplied as a ready-to-use aqueous solution for industrial water and process chemistry.

It functions as a scale inhibitor, corrosion inhibitor, and chelating agent across a range of water-intensive industrial systems. In cooling water and boiler water treatment, it prevents calcium carbonate scale.

The product also prevents calcium sulfate and calcium phosphate scale deposition on heat exchange surfaces, extending equipment service life. Metalworking and industrial cleaning formulations use it to sequester hardness ions.

By buffering pH, it improves the stability and performance of aqueous process fluids. In textile processing, it controls metal ion interference during dyeing and finishing, helping achieve consistent color results.

Paper manufacturing operations apply it to inhibit scale buildup in process water circuits and protect equipment from corrosion. This ensures operational efficiency and reduces maintenance costs in heavy industrial settings.

PBTC sodium salt is typically supplied as a liquid aqueous solution, with active content concentrations commonly in the range of 50% solids. It is available in technical grade for industrial applications.

Bulk supply in IBC containers and drums is standard, with grades aligned to water treatment and industrial process specifications. This high-performance additive is essential for modern chemical water management.
