Dynasylan® GLYEO

Technical Datasheet | Supplied by Evonik
Dynasylan® GLYEO by Evonik is a 3-glycidyloxypropyltriethoxysilane compound. Acts as an adhesion promoter, crosslinking agent and/or surface modifier. Provides improved mechanical properties like flexural strength, tensile strength, impact strength and modulus of elasticity. Offers improved moisture and corrosion resistance. Shows improved electrical properties like dielectric constant and volume resistivity. Can also improve processing properties as better filler dispersion, improved rheological behavior like viscosity reduction, Newtonian behavior and increased filler loading. Dynasylan® GLYEO is listed on EINECS/ELINCS, AICS, PICCS, TSCA, IECSC, ENCS, ECL and REACH. It has a shelf life of minimum 12 months.

Hansen Solubility Parameters

[14.4, 5.1, 3.7]
[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® GLYEO. A practical determination of these HSP values would provide higher certainty. Learn More.
