Evonik (formerly Degussa AG) MTMS, Dynasylan MTMS, methyltrimethoxysilane Overview:
Dynasylan ® MTMS methyltrimethoxysilane (Also known as:Silane coupling agent MTMS,Adhesive MTMS)Developed and produced by Evonik Evonik Degussa AG, an alkyl trialkoxysilane, is an important component of the sol gel system.
Dynasylan ® MTMS methyltrimethoxysilane is a colorless, low viscosity liquid. Dynasylan ® MTMS methyltrimethoxysilane is considered a tri functional silane because all three alkoxy groups can be hydrolyzed. In addition, Dynasylan ® MTMS contains a methyl group that endows the product with organic properties. The silicon hydroxyl group generated by hydrolysis, followed by condensation reaction, achieves the formation of very stable silicon oxygen bonds (- Si-O-Si -). Once a certain amount of silanol groups are generated, condensation and hydrolysis proceed in parallel. The absolute and relative hydrolysis rates, as well as the degree of condensation, are determined by a series of factors. The main factors are pH value, concentration, solvent, temperature, and catalyst.
Dynasylan ® MTMS methyltrimethoxysilane functionality:
The reaction between Dynasylan ® MTMS methyltrimethoxysilane and water is better than that of Dynasylan ® MTES needs to be fast.

Evonik (formerly Degussa AG) MTMS, Dynasylan MTMS, methyltrimethoxysilane application:
In some sol-gel applications, Dynasylan ® MTMS Methyl trimethoxysilane is partially hydrolyzed to produce intermediate products that can further crosslink under high temperature conditions. This pre hydrolysis usually involves other organic functional silanes (such as Dynasylan) ®GLYMO)、 Silicates or even silica hydrosols are involved. This intermediate product can be prepared by adding organic resins or inorganic nanoparticles, such as AEROSIL ®, Further modification. Inorganic/organic network structures can also be formed by adding organic functional groups (such as aminopropyl) to silane, organic resins, and through standard organic polymerization methods. According to this principle, anti fouling coating with higher UV stability than traditional organic coatings can be achieved. At the same time, compared to traditional resins, it can generate more fire-resistant materials.
