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 organophosphates. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Appearance: Colorless or light yellow transparent liquid Active acid : 50.0 min Phosphorous acid as PO33-%: 0.8 max Phosphorous acid as PO43-%: 0.5 max Density 20¡æg/cm3: 1.27 min pH 1 solution: 1.5~2.0.
