Frequently Asked Questions

What is PBTC Na4?
PBTC·Na4 has low phosphorus content, because it has the structural characteristics of phosphonic acid and carboxylic acid, it has good scale and corrosion inhibition performance, which is better than the commonly used organic phosphonic acid, especially at high temperatures.

What is PBTC Na4 used for?
PBTC·Na4 is the most widely used compound of high-efficiency scale and corrosion inhibitors. It is one of the products with the best performance, and it is also an excellent stabilizer for zinc salts. PBTC·Na4 is widely used in the corrosion and scale inhibition of circulating cooling water systems and oil field water injection systems, especially suitable for compounding with zinc salts and copolymers, and can be used in high temperature, high hardness, high alkali and occasions that require high concentration multiples. It can be used as chelating agent and metal cleaning agent in the washing industry. PBTC·Na4 is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphorus, and azoles.
