- 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.
Applications & Uses
- Markets
- Application Characteristics
- 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.
