With regulations aimed at decreasing VOCs and the development of new waterborne polymer systems and other technologies to meet these regulations, obtaining the combination of desired properties for specific applications and formulations has become even more challenging and complex. Evonik Coating Additives can help obtain these properties.
In today's environmentally conscious marketplace, formulators are challenged to be sensitive to the potentially negative environmental impacts of their systems. As global trends and regulations move away from many traditional materials, formulators are looking to transition to more environmentally friendly systems. Formulators are also challenged with reducing or even eliminating VOCs from their architectural systems.
As problems related to pigment dispersions become more frequent and as requirements regarding
color reproducibility become increasingly rigorous, new demands for pigment wetting agents and dispersants are required to resolve these pigment stabilization issues. Over the past 20 years, advances in polymeric dispersants have made significant improvements in the process of wetting and stabilizing pigments. As a result, many dispersant technologies that better stabilize small pigment particles and that better prevent flocculation are emerging in the marketplace. This paper will explain pigment and dispersant interfaces and how harmonizing and optimizing these interactions will lead to a better pigment dispersion.
