Polysilazanes—Binders That Make a Difference to Surfaces

EMD COLLAGE
Polysilazanes are pre-ceramic polymers with a silicon-nitrogen backbone. In recent years they have developed as a high-performance binder in protective coatings for transportation vehicles, commercial and residential buildings, and industrial plants. This article reviews their structure-property relationship and highlights their performance in high-temperature, surface hardness, weathering and corrosion protection, and anti-graffiti applications.

My recent articles on Hansen Solubility Parameters (CoatingsTech, May, July, and September 2018) have raised questions about what other solvent properties are important and about how to choose solvents. The main job of solvents is as carriers for resins, pigments, and other components. Other functions include controlling viscosity for application and flow-out, aiding in film formation, and wetting of pigments...

Highly Versatile Aluminum Flake for Water, Solvent and Ultra-low VOC Coatings and Inks

Highly Versatile Aluminum Flake for Water, Solvent and Ultra-low VOC Coatings and Inks
Liquid coatings and inks are facing increased pressure with respect to the presence of volatile organic compounds (VOCs). As a result, ink and coating formulators have to balance safety, regulatory, and emission standards while meeting their customers’ performance requirements. For low-VOC, metallic formulations, aluminum pigments are used to impart a desirable silver or metallic effect with excellent hiding power. In...
