- Handling
- Dynasylan® MTMS is listed on EINECS/ELINCS, AICS, DSL/NDSL, PICCS, TSCA, ECS, ENCS and ECL., 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. This pre-product can be modified even further by addition of organic resins or inorganic nanoparticles such as AEROSIL®.
