Dynasylan® MTMS

Technical Datasheet | Supplied by Evonik
Dynasylan® MTMS by Evonik is a methyltrimethoxysilane grade. Acts as a crosslinker. It is a colorless, low-viscosity liquid. It is regarded as trifunctional since all three alkoxy groups are able to hydrolyze. Additionally, it contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst. In some sol-gel applications Dynasylan® MTMS is partially hydrolyzed to form a pre-product that can be further crosslinked using temperature. This prehydrolysis often is done in conjunction with other organofunctional silanes (e.g. Dynasylan® GLYMO), silicic acid esters or even an aqueous silica sol. Listed with EINECS/ELINCS, AICS, DSL/NDSL, PICCS, TSCA, IECSC, ENCS, ECL and REACH. It has a minimum shelf life of 12 months.

Hansen Solubility Parameters

[14.1, 3.9, 4.1]
[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® MTMS. A practical determination of these HSP values would provide higher certainty. Learn More.
