Storage stability is a defining requirement for industrial waterborne formulations. EVA–PU systems are particularly sensitive due to differences in stabilization mechanisms. Initial visual inspection provides limited information. Many incompatible systems remain visually acceptable for several hours... read more
Many EVA–PU formulations perform well in the laboratory but fail during scale-up. The main reason is that laboratory conditions often mask sensitivities related to shear, addition rate, and time-dependent stability. In small-scale tests, materials are typically added slowly and mixed uniformly. In p... read more
Industrial waterborne formulations must tolerate process variation, storage, and transportation without failure. EVA–PU systems that rely on a single control factor rarely meet these requirements. Robust formulations balance multiple elements: compatible pH ranges, controlled ionic strength, appropr... read more
Ionic strength is underestimated factors in waterborne formulation stability. Unlike pH, it is not always measured directly, yet it strongly influences particle interactions. In EVA–PU systems, every formulation component contributes to ionic strength: neutralizers, dispersants, surfactants, preserv... read more
Blending order is frequently treated as a processing detail, but in waterborne polymer systems it is a fundamental stability parameter. This is especially true for EVA–anionic PU blends. When PU dispersion is added into EVA latex, the highly charged PU particles encounter a relatively weakly stabili... read more
