In many waterborne formulations, pH adjustment is the tool used to address EVA–PU incompatibility. While pH control is important, relying on it alone often leads to short-lived success and delayed failures. Raising EVA latex pH from acidic to near-neutral conditions can reduce immediate instability... read more
Blending EVA latex with anionic polyurethane (PU) dispersions is widely used in waterborne adhesives, coatings, and impregnation systems. However, formulators often encounter instability issues such as flocculation, viscosity increase, or phase separation. While pH is frequently blamed, the root cau... read more
