Dynasylan® MTES

1 of 42 products in this brand
Dynasylan® MTES is an alkyltrialkoxysilane, plays a vital role in sol-gel systems. It appears as a colorless, low-viscosity liquid. Utilization involves hydrolysis catalyzed by acid or alkali. As a trifunctional compound, all three alkoxy groups partake in this reaction, enriched by the added organic character from the methyl group. Hydrolysis generates silanol groups that subsequently form highly stable siloxane bonds (-Si-O-Si-) through condensation. This parallel process occurs after a certain amount of silanol groups emerge. The pace of hydrolysis and condensation depends on pH, concentration, solvent, temperature, and the catalyst.

Low Viscosity

Reactivity
  • Dynasylan® MTES reacts slower with water than Dynasylan® MTMS.
  • For rapid hydrolyzation a hydrolysis catalyst (mineral acids or ammonia, or even acetic acid and amines) or a cosolvent such as ethanol can be added.

Application Characteristics
  • In some sol-gel applications Dynasylan® MTES is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature.
  • This prehydrolysis is often done in conjunction with other organofunctional silanes, silicic acid esters (e.g. Dynasylan® A) or even a aqueous silica sol.
  • This preproduct can be further modified 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.
