Dynasylan® PTMO
- CASE Ingredients Features
- Low Viscosity
- Chemical Family
- Silanes
Dynasylan® PTMO exhibits trifunctional behavior as all three alkoxy groups can hydrolyze. This compound also features a propyl group that imparts hydrophobic attributes to sol-gel coatings. Hydrolysis initiates silanol group formation, leading to subsequent condensation reactions that yield stable siloxane bonds (-Si-O-Si-). Condensation progresses alongside hydrolysis, provided a certain amount of silanol groups are present. The speed and ratio of hydrolysis and condensation hinge on factors like pH, concentration, solvent, temperature, and catalyst.

- Applications
In some sol-gel applications Dynasylan® PTMO is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature.; This pre-hydrolysis 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 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.; The mixture is then cured using standard organic methods.; In this way it is 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. Dynasylan® PTMO reacts faster with water than Dynasylan® PTEO.; To regulate the rate of hydrolysis and condensation a catalyst (mineral acids or ammonia, or even acetic acid and amines) can be added.; Hydrolysis can also be furthered by adding a co-solvent such as an alcohol.
