Dynasylan® VTMOEO

Technical Datasheet | Supplied by Evonik
Dynasylan® VTMOEO by Evonik is a vinyltris(2-methoxyethoxy)silane compound. Acts as an efficient adhesion promoter and/or surface modifier. It is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable 2-methoxyethoxysilyl group. The dual nature of its reactivity allows this grade to bind chemically to both inorganic materials (like glass, metals & fillers) and organic polymers (such as thermosets, thermoplastics & elastomers). Improves the mechanical and electrical properties of mineral-filled polymers, especially after exposure to moisture. Polymer dispersions (such as styrene acrylics), modified with Dynasylan® VTMOEO show improved adhesion strength in wet conditions and wet scrub resistance. It is listed on ECL, EINECS/ELINCS, AICS, DSL/NDSL, PICCS, TSCA, IECS, REACH and ENCS. The minimum shelf life of this product is 12 months.

Hansen Solubility Parameters

[14.8, 4.4, 4.5]
[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® VTMOEO. A practical determination of these HSP values would provide higher certainty. Learn More.
