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.
Dynasylan® 4148 can be added neatly to a blend of filler or pigment and resin, or it can be used for the pretreatment of the filler or pigment.
Today there is a multitude of possibilities to benefit from the use of Dynasylan® in a responsible and sustainable way. New application areas have constantly been discovered by the combination of our research and development along with close contacts to our customers. Whether you are thinking about Dynasylan® products for a well-established application or for the next cutting-edge idea, you will find the right solution with our Dynasylan® products.
