Maximizing Pigment and Overall Paint Performance with Multifunctional Additives

Developing high-performance formulations with minimal VOC emissions remains a challenge for formulators across a variety of paints and coatings applications. Alkanolamines, which are well-known for their exceptional ability to wet, grind, and stabilize a wide range of pigments, can help formulators achieve an optimal blend of other wetting and dispersing agents, while reducing the VOC profile of a formulation. With their innate affinity for pigment surfaces and the ability to substitute conventional counter ions of surfactants and dispersing agents, alkanolamine additives play an essential role in influencing, and improving various critical aspects of paint and dry-film performance, such as initial particle size distribution, storage stability, hiding power, corrosion protection, and colour strength. This comprehensive investigation uncovers new ways to leverage the true potential of the unique characteristics of alkanolamines when interacting with TiO₂, organic pigments, or anti-corrosion pigments, making them an indispensable formulating tool for developing and manufacturing the next generation of high-performance paints and coatings.
