Silicone Surfactants are essential for optimizing the performance of water-based paints and coatings, particularly in improving levelling and avoiding crater formation. When selecting the right surfactant, the polarity of its structure is crucial because it directly affects solubility in water, ensuring better integration but potentially increasing foam formation and stabilization. On the other hand, a less polar surfactant reduces water compatibility and foam formation but potentially affecting the wetting properties.

Our new ORDISOL® SWT-49 features a less polar structure compared to the reference product. This results in lower water compatibility and significantly less foam formation in water-based systems. However, despite being less compatible with the system, ORDISOL SWT-49 maintains the same surface tension curve as the reference product, indicating that is successfully positions itself at the interface. This ensures effective wetting and anticratering performance while minimizing unwanted foam.
ORDISOL® SWT-49 is an all-purpose silicone surfactant specifically designed for aqueous systems. It provides formulators with an effective solution for advanced paints and coatings applications, particularly where foam reduction is essential.
Come and learn about these solutions at stand 3A-222 of the ECS2025 exhibition from March 25 to 27.
