Description
Properties: PBTCA is light yellow transparent liquid. It has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale inhibition properties for calcium carbonate and calcium sulfate. PBTCA has low content of phosphorus and easy to dissolve with zinc salt comparing with organic phosphoric acid. Therefore，it’s widely used by complexing agent.
Usage: PBTCA is widely used as the scale and corrosion inhibitor in circulation chilled water system and water injection system.
