Manufacturing of Mineral paints

VAE (vinyl acetate/ethylene) polymers are unique due to their ability to form films at lower temperatures—thanks to the hydroplasticization effect where water acts as a temporary plasticizer—and their inherently low VOC characteristics. This makes VAE polymer dispersions particularly attractive for formulations requiring low coalescent content, which in turn reduces odor and environmental impact. Because of these properties, VAE-based paints often offer excellent scrub resistance and touch-up performance, ideal for areas subject to frequent cleaning. However, when used as the sole binder, conventional VAE formulations can sometimes fall short in block resistance (the tendency to stick to adjacent surfaces) and in managing dirt pick-up in non-flat finishes.

VAE compared to Acrylics

In comparison, acrylic polymers (often the benchmark for architectural coatings) generally deliver superior block resistance, long-term durability, and enhanced weatherability—qualities that are especially crucial in exterior applications. Historically, many paint formulators have tackled the inherent limitations of VAE binders by blending them with acrylics, thereby leveraging the cost and environmental benefits of VAEs while reinforcing the paint’s overall performance. Recent advancements in VAE technology—including modifications through innovative inclusion techniques—are addressing these shortcomings, expanding their application scope to include even higher sheen and exterior paints. Ultimately, the choice between VAE and acrylic (or even polyester or alkyd) polymers depends on the particular performance attributes needed, environmental regulations (low VOC mandates), processing conditions, and cost considerations in your paint formulation strategy. However VAE offers supreme colour (UV) stability, especially with organic pigments, low VOC values and the possibility to develop biocide free paints with special high PH dispersions or by using dry VAE powders.

Beyond these points, VAE polymers can also interact with different substrates and support eco-friendly technologies. VAE’s polymer chemistry are further pushing the boundaries of performance in architectural coatings.
