Dynasylan® 1124

Technical Datasheet | Supplied by Evonik
Dynasylan® 1124 by Evonik is a bis(trimethoxysilylpropyl)amine grade with excellent crosslinking properties. Acts as an adhesion promoter and surface modifier. This grade provides improvement in flexural strength, tensile strength, impact strength, modulus of elasticity, moisture and corrosion resistance. Offers benefits such as improvement in wet-out, homogeneous distribution of inorganic fillers in polymer matrices, rheological behavior like reduction in viscosity and newtonian behavior. Dynasylan® 1124 is listed in DSL/NDSL, PICCS, TSCA, IECSC/TCSI, ECL, EINECS/ELINCS/SWISS, AICS and NZIoC. It has a minimum shelf life of 12 months.

Hansen Solubility Parameters

[12.8, 2.6, 4.4]
[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® 1124. A practical determination of these HSP values would provide higher certainty. Learn More.
