PBTC·Na4, Phosphonobutane Tricarboxylic Tetrasodium
Properties:
PBTC·Na4 is a tetrasodium salt of phosphonobutane tricarboxylic acid. Its structure contains phosphonic acid and carboxylic acid groups, enabling 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.

Uses:
PBTC·Na4 is a widely used and highly effective composite scale and corrosion inhibitor agent. It is also an excellent stabilizer for zinc salt. Therefore, it is used as a scale and corrosion inhibitor in circulating cool water and oilfield refill water systems, especially 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 with zinc salt, copolymer, organophosphine, imidazole, and other water treatment chemicals.
Packing and Storage:
25kg/bag, customers’ requirement. Storage for one year in a shady room and dry place.
