Self-Crosslinking Surfactant-Free Acrylic Dispersions for High-Performance Coatings Applications
Acrylic dispersions have found widespread use in modern coatings technology. They have excellent durability, which makes them suitable for indoor and outdoor decorative paints, and can be formulated into high-resistance coatings for industrial uses. Generally, for high-performance coatings in a variety of applications, several key properties are of importance.
Especially high glass-transition temperature (Tg) and high molecular-weight (Mw) acrylic dispersions can achieve very good application properties, but high levels of coalescents are required for good film formation. With the ongoing drive toward more environmentally friendly coatings, the aim is to reduce the coalescent demand further with zero VOCs as the ultimate goal.
