Dynasylan ® 4144 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® 4144 features chemical polarity yet remaining chemically not reactive. A of such the product is used as a hydrophilic compatibilizer rather than a covalent adhesion promoter.
Dynasylan® 4144 permits workable viscosities at well over 250 phr aluminum trihydroxide loading in unsaturated polyester resins. Further more, Dynasylan® 4144 can be used as anti-settling agent for corrosion inhibitors in glycol based cooling agents. As a non-coupling silane Dynasylan® 4144 can also be used as a slipping agent to simply modify a surface. view less

Dynasylan® 6498 is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and ethoxy groups. Dynasylan® 6498 is a colourless, nearly odorless low viscosity liquid. Dynasylan® 6498 is an excellent compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (e.g. EPDM, EVA, PE). The high boiling point of Dynasylan® 6498, together with its high flash point, gives it outstanding advantages with respect to safety and handling during processing. From an environmental viewpoint it should be noted that the amount of released hydrolysis ethanol (VOC) is significantly reduced compared to monomeric vinyl silanes. view less
