Technical Datasheet | Supplied by Evonik
Dynasylan® SILBOND® 40 by Evonik is an ethyl polysilicate liquid with low viscosity. It is a concentrated form of available silica. It is a partially hydrolyzed mixture of monomers, dimers, trimers and higher polymers. Average -Si-O-Si- chain length is approximately five. It is hydrolyzed in water and miscible with organic solvents. Dynasylan® SILBOND® 40 is used in the manufacture of less concentrated or more highly hydrolyzed binders. It has a minimum shelf life of 12 months.

Hansen Solubility Parameters

[13.6, 3.4, 3]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Dynasylan® SILBOND® 40. A practical determination of these HSP values would provide higher certainty. Learn More.
