2-Phosphonobutane-1,2,4-Tricarboxylic Acid Sodium Salt (PBTC•Na4) is a high-performance water treatment agent engineered for superior scale and corrosion inhibition. Featuring a unique molecular structure that integrates both phosphonic acid and carboxylic acid groups, it provides exceptional stability and effectiveness in challenging industrial environments, outperforming traditional organophosphines particularly under high-temperature conditions.
Designed for versatility, PBTC•Na4 serves as an excellent stabilizer for zinc salts and exhibits strong chlorine oxidation tolerance. It is widely deployed across circulating cooling water systems, oilfield refill water systems, and industrial cleaning sectors as a powerful chelating agent and metal detergent, ensuring optimal system efficiency and equipment longevity.
