DYNASYLAN 4150

DYNASYLAN 4150 is a non-ionic silane which imparts outstanding wetting and dispersibility to fillers and pigments. DYNASYLAN 4150 features chemical polarity yet remaining chemically not reactive. Such a non-coupling filler or pigment surface-modifier silane is used as a hydrophilic compatibilizer rather than as a covalent adhesion promoter. Due to its excellent wetting behaviour, DYNASYLAN 4150 helps to control rheological properties and to reduce viscosity, allowing extremely high fillers loads in water and polar vehicles, permitting to achieve a powdery velvet touch sensation. Furthermore, DYNASYLAN 4150 can be used as anti-settling agent for fillers and pigments, ensuring the stability and improving the texture of aqueous and glycol-based formulations. DYNASYLAN 4150 treated fillers and pigments enhances various properties of the finished formulations such as workability, strength, durability and aesthetics.
