What is PBTCA? What are the advantages?

Today we will introduce a magical substance - PBTCA, which is 1,2,4-tricarboxylic acid-2-phosphonylbutane. It not only has low phosphorus content, but also performs well in scale and corrosion inhibition, especially at high temperatures. Its scale inhibition performance is far superior to commonly used organic phosphonic acids.
Its structure contains phosphonic acid and carboxylic acid, therefore it has good scale and corrosion inhibition performance. Compared to commonly used organic phosphonic acids, it performs better at high temperatures and can improve the solubility of zinc, has strong resistance to chlorine oxidation, and has good synergistic properties in combination. It is widely used in the compounding of efficient scale and corrosion inhibitors, especially suitable for compounding with zinc salts, copolymers, etc., and can be used in various operating scenarios that require high concentration ratios.

In addition to water treatment, PBTCA can also be used as a metal cleaning agent and chelating agent in the washing industry. Usually used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphorus, azoles, etc. When added separately, it is recommended to add 5-15mg/L.
Due to PBTCA being an acidic substance, please pay attention to labor protection and avoid skin and eye contact. If accidentally in contact, immediately rinse with plenty of water.
