Properties:

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, has good

chlorine oxidation tolerance and good composite synergy.

Usage:

PBTCA is a high efficient agent as scale and corrosion inhibitor and vanadium inhibitor. It is the excellent

stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as

scale and corrosion inhibitor,suitable to composite with zinc salt and copolymer. It can be used in

situations of high temperature, high hardness, high alkali and high concentration index.

Package:

Normally In 250kg net Plastic Drum, 1250kg IBC drum can also be used as required.

Safety Protection:

Acidity, Avoid contact with eye and skin, once contacted, flush with water
