EVA–PU blends are used in a wide range of applications, including adhesives, coatings, and impregnation systems. Each application imposes different requirements on stability and performance. Adhesive systems often require higher solids content, increasing particle interaction frequency and destabili... read more
Additives play a critical role in EVA–PU systems, yet they are often evaluated only for their primary function. In reality, each additive also influences colloidal stability. Dispersants, wetting agents, defoamers, and preservatives can introduce additional ionic species or interact with particle su... read more
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
