PBTCA introduction

Dispersant is a molecule at the same time in the lipophilic and hydrophilic nature of the two opposing surfactant. Those can be difficult to homogeneous dispersion of inorganic dissolved in the liquid, The solid particles of paint, but also to prevent the solid particles and the settlement pool, a stable suspension of pharmaceutical requirements. 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.
