Dynasylan® 1122

Technical Datasheet | Supplied by Evonik
Dynasylan® 1122 by Evonik is a Bis(3-triethoxysilylpropyl)amine. Acts as an adhesion promoter and as a surface modifier. Provides good flexural strength, tensile strength, impact strength and modulus of elasticity. Offers benefits such as improved moisture and corrosion resistance, improved rheological behavior like reduction in viscosity and improved newtonian behavior like higher degree of filling. Dynasylan® 1122 is listed on EINECS, NDSL, PICCS, TSCA, IECSC, ECL

Hansen Solubility Parameters

[13.7, 2.9, 2.9]
[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® 1122. A practical determination of these HSP values would provide higher certainty. Learn More.
