Coagulant carryover is an unavoidable reality in glove dipping processes. Calcium nitrate and calcium chloride solutions inevitably enter the latex tank during repeated dipping cycles. As divalent calcium ions accumulate, they strongly neutralize the surface charge of NBR latex particles. This leads... read more
NBR latex is the dominant material for disposable and industrial glove manufacturing due to its oil resistance and mechanical performance. However, dipping applications impose unique stability requirements that differ significantly from coating or adhesive systems. In a typical glove production line... read more
Robust EVA–PU formulations are the result of deliberate system design rather than aggressive correction. They balance multiple factors to achieve long-term stability and predictable performance. Key elements include compatible pH ranges, controlled ionic strength, appropriate blending order, and the... read more
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
