PBTC·Na4 is a tetrasodium salt of phosphonobutane tricarboxylic acid. It has a low content of phosphoric. Its structure contains both phosphonic acid and carboxylic acid groups, which enable its good scale and corrosion inhibition properties.
PBTC·Na4 scale inhibition property is far better than that of organophosphates under high temperatures. The phosphonobutane tricarboxylic tetrasodium salt can improve the solubility of zinc salt. It has good chlorine oxidation tolerance and good composite synergy. The solid-state PBTC·Na4 is easy deliquescence.

PBTC·Na4 is the widely used and high effective agent as a composite scale and corrosion inhibitor, it is also an excellent stabilizer for zinc salt. It is used as a scale and corrosion inhibitor in circulating cool water systems and oilfield refill water systems, especially used together with zinc salt and copolymer. PBTC·Na4 can be used in situations of high temperature, high hardness, high alkaline, and high concentration index, PBTC·Na4 is used as a chelating agent and metal detergent in lavation fields.
PBTC·Na4 is usually used together with zinc salt, copolymer, organophosphine, imidazole, and other water treatment chemicals.
