Evonik (formerly Degussa AG) 9896, organic silane coupling agent Dynasylan 9896, oligomeric alkyl silane Overview:
Dynasylan ® 9896 oligomeric short chain alkyl functional silane (Also known as:Silane coupling agent 9896,Thickener 9896,Dispersant 9896）Developed and produced by Evonik Degussa AG, it is an oligomeric short chain alkyl functional silane. Dynasylan ® 9896 oligomeric short chain alkyl functional silane is a colorless to light yellow clear liquid that is soluble in commonly used organic solvents such as petroleum ether, toluene, and alcohol. Due to its low volatility and viscosity, Dynasylan ® 9896 oligomeric short chain alkyl functional silane is an easy to dispose of additive.
In Dynasylan ® During the hydrolysis reaction of 9896 oligomeric short chain alkyl functional silane with water, a certain amount of VOC (volatile organic compounds) will be released in the form of alcohols. From an environmental perspective, compared to single molecule alkyl silane, the total amount of hydrolyzed alcohols (VOCs) released by it is significantly reduced, below 100g/L.
The high boiling point and flash point of Dynasylan ® 9896 oligomeric short chain alkyl functional silane give it significant advantages in terms of safety and operational processes.‘
Dynasylan ® 9896 oligomeric short chain alkyl functional silane reactivity:
Due to its unique structure, Dynasylan ® 9896 oligomeric short chain alkyl functional silane exhibits strong hydrophobicity on the substrate surface and forms chemical bonds with it. Using Dynasylan ® 9896 silane can achieve:
• Especially in non-polar media such as polyolefins, inorganic compounds treated with Dynasylan ® 9896 oligomeric short chain alkyl functional silane (such as titanium dioxide, ATH, or MDH) are dispersed, exhibiting excellent compatibility.
• Dynasylan ® 9896 oligomeric short chain alkyl functional silane, like all silanes, forms covalent bonds and does not migrate out of the final complex.
• Make it possible to add a high amount of filling material. Compared to untreated compounds, good compatibility leads to lower viscosity.
Main performance:
● Increase the dispersion rate of fillers
● Reduce water intake
● Simple operation process
● Better compatibility
Dynasylan ® 9896 oligomeric short chain alkyl functional silane is a colorless to light yellow clear liquid that is soluble in commonly used organic solvents such as petroleum ether, toluene, and alcohol.
Applied in industrial fields such as fillers and pigments, in filler modification, the treated surface has high hydrophobicity and good dispersibility
Evonik (formerly Degussa AG) 9896, organic silane coupling agent Dynasylan 9896, application of oligomeric alkyl silane:
Dynasylan ® 9896 oligomeric short chain alkyl functional silane can be used as a surface treatment agent for hydrophobic treatment (e.g. on inorganic pigments, mineral fillers surfaces). The unique compound properties of short chain alkyl functional groups in Dynasylan ® When 9896 oligomeric short chain alkyl functional silane is used to treat minerals or pigments, it is incorporated into polymers such as polyethylene and polypropylene. Generally, we recommend Dynasylan ® The dosage of 9896 is 0.5-1.5% of the weight of the filler or pigment. Dynasylan ® 9896 oligomeric short chain alkyl functional silane has excellent applications as a dispersant and hydrophobic modifier in mineral filled composites. Dynasylan ® 9896 forms covalent bonds with inorganic substances and does not migrate, therefore Dynasylan ® 9896 endows mineral filled plastics with printability. Dynasylan in the presence of water vapor and low pH conditions ® The ethoxy group of 9896 oligomeric short chain alkyl functional silane undergoes hydrolysis, generating alcohols and reactive silanol groups. These silicon hydroxyl groups interact with fillers through silicon oxygen bonds. Dynasylan ® 9896 oligomeric short chain alkyl functional silane can be used in many other applications, such as fillers and pigment coatings, dispersions, etc. By using Dynasylan ® Short chain alkyl functionalized silane with 9896 oligomers can improve the following typical properties when added to polymers:
• Improve the dispersion of fillers
• Good operational performance
• Significantly reduce water intake
