Dynasylan® 9896 is an oligomeric short-chain alkylfunctional silane.
Dynasylan® 9896 is a clear, colourless to slightly yellow liquid and soluble in common organic solvents (e.g. petroleum ether, toluene, alcohol). Because of its low volatility and viscosity Dynasylan® 9896 is an easy-to-handle additive.
During the hydrolysis reaction between water and Dynasylan® 9896 a certain amount of VOC (volatile organic compound) is released as ethanol. From an environmental standpoint it should be noted that the amount of released hydrolysis ethanol (VOC) is significantly reduced compared to monomeric alkyl silanes and is below 100 g/l.
The high boiling point of Dynasylan® 9896, together with its high flash point, gives outstanding advantages with respect to safety and handling during processing.
Typical Applications
- improved filler dispersion
- good processability
- significantly reduced water-uptake
Benefits at a glance
- Particularly in non-polar media (e.g. polyolefins etc.). Dynasylan® 9896 treated inorganic substrates (e.g. titanium dioxide, ATH, or MDH) dispersion show excellent compatibility.
- Dynasylan® 9896 as all silanes forms covalent bonds and will not deplead in the final compound.
- Higher filler loadings are possible. Better compatibiity results in lower viscosity compared to unmodified compounds.
