- Silanes
Dynasylan® MTMS is an alkyltrialkoxysilane, holds a pivotal role in sol-gel systems. It appears as a colorless, low-viscosity liquid. Notably trifunctional, all three alkoxy groups possess hydrolytic capability, while the methyl group introduces organic character. Hydrolysis instigates the formation of silanol groups, which subsequently engage in condensation reactions to establish robust siloxane bonds (-Si-O-Si-). This condensation process coincides with hydrolysis after a threshold of silanol groups emerges. Hydrolysis and condensation rates depend on pH, concentration, solvent, temperature, and the catalyst.

- Reactivity
Dynasylan® MTMS reacts faster with water than Dynasylan® MTES.; Dynasylan® MTMS is regarded as trifunctional since all three alkoxy groups are able to hydrolyze.; Additionally Dynasylan® MTMS 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.

Dynasylan® MTMS are available in 25 kg, 190 kg and 900 kg drums/ containers.
- Applications
In some sol-gel applications Dynasylan® MTMS is partially hydrolyzed to form a preproduct 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.; This preproduct can be modified even further by addition of organic resins or inorganic nanoparticles such as AEROSIL®.; It is also possible to construct an inorganic/organic network by adding silanes containing organofunctional groups (e.g. aminopropyl groups) and organic resins and polymerizing using standard organic methods.; This principle makes it possible to obtain mar resistant coatings having a higher UV- stability than traditional organic coatings.; This can also lead to more flame resistant materials than using traditional resins.
