DYNASLYAN 4148 is a polyethyleneglycol-functional alkoxysilane that is soluble in water and most organic solvents. It helps to control rheological properties and reduce viscosity in highly filled systems. Unlike other organofunctional silanes, DYNASYLAN 4148 features chemical polarity while remaining chemically inert. This makes it suitable for use as a hydrophilic compatibilizer rather than a covalent adhesion promoter. DYNASYLAN 4148 allows for workable viscosities even at high filler loadings. It can also be used as an anti-settling agent. As a non coupling silane, DYNASYLAN 4148 acts as an effective slipping agent to modify surfaces. Key benefits include improved dispersion of fillers, enhanced properties at high loadings and better surface characteristics. These attributes make DYNASYLAN 4148 well suited for formulating high performance, optimized solutions for various industrial applications.
