Synopsis

Siloxane-based additives are critical tools in coating applications because their structures can be varied in order to provide a broad range of performance benefits in many types of formulations and chemistries. Surfactants and defoamers are some of the more commonly recognized additive classes, but many other functionalities can be derived from siloxane chemistries, particularly attributes related to surface control such as flow and leveling, slip, scratch resistance, and haptic properties. This extensive range of performance is achievable due to the broad flexibility inherent in siloxane chemistry, allowing a fine-tuned balance of compatibility, incompatibility, and surface activity.

As with many additive types, there is no “universal” surface control additive but siloxane-based surface control additives offer the formulator useful tools that can be employed to create high-performance coatings. Each formulation and the application have different demands for which the new TEGO® Glide 49x family offers a solution. The newest product in the family is TEGO® Glide 496. It is suitable for both solvent- and water-based formulations providing excellent compatibility and scratch-resistance improvement in various systems.
