Superiority
2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA) has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, PBTCA has good chlorine oxidation tolerance and good composite synergy.

Usage:
PTBCA is a high efficient agent as scale corrosion inhibitor. It is the excellent stabilizer fzinc salt. It is widely used in circulating cool water system oilfield refill water system as scale corrosion inhibitor, suitable to composite with zinc salt copolymer. It can be used in situations of high temperature, high hardness, high alkali high concentration index. In lavation fields, it is used as chelating agent metal detergent.
PBTCA is usually used together with zinc salt, copolymer,ganophosphine, imidazole other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.
