Seeking additives to render the surface of coatings hydrophobic or hydrophilic

 
Today's coatings technology is driven by a number of technical and commercial challenges. Additives being important ingredients in the formulation of coatings can be advantageously used to valorize the related materials and advance the technology. Surface properties - such as leveling, slip, ease of cleaning, recoatability, hydrophobic or hydrophilic properties - are strongly influenced by the surface-active additives. These additives segregate toward the coating-air interface and tailor the surface properties. The performance and properties that these additives attribute to the coating depend on their chemical compositions and their structures. This presentation will update sophisticated additive technologies, with their highly structured polymer architectures derived from the macromonomer technology.
