Dynasylan® 4148

Dynasylan® 4148 helps to control rheological properties and to reduce viscosity in highly-filled polymer systems, like aluminum trihydroxide-filled polyesters or SMC-pastes. Contrary to most other organofunctional silanes, Dynasylan® 4148 features chemical polarity yet remaining chemically not reactive. Such a product is used as a hydrophilic compatibilizer rather than a covalent adhesion promoter. Dynasylan® 4148 permits workable viscosities at well over 250 phr aluminum trihydroxide loading in unsaturated polyester resins. Further more, Dynasylan® 4148 can be used as anti-settling agent for corrosion inhibitors in glycol based cooling agents. As a non-coupling silane Dynasylan® 4148 can also be used as a slipping agent to simply modify a surface.
