DYNASYLAN 4148

DYNASLYAN 4148 is a ready-for-use silane that is soluble in water and most organic solvents. It helps to control rheological properties and reduce viscosity in highly-filled polymer systems. DYNASYLAN 4148 features chemical polarity yet remaining chemically not reactive. It can be used as a hydrophilic compatibilizer rather than a covalent adhesion promoter. It permits workable viscosities at well over 250 phr loading in unsaturated polyester resins. It can also be used as an anti-settling agent for corrosion inhibitors in glycol based cooling agents. As a non-coupling silane, it can dramatically reduce the dispersion viscosity of aluminum trihydroxide and many other fillers and pigments. It helps to increase pigment dispersion predominantly in aqueous media, thus leading to an enhanced gloss of a typical coating. It can be used as a slipping agent to simply modify a surface or as a lubricant and wetting agent in combination with silane coupling agents.
