Dynasylan® 9165 is a colourless, low-viscosity liquid. Dynasylan® 9165 is regarded as trifunctional since all three alkoxy groups can hydrolyze. Dynasylan® 9165 also contains a phenyl group that exhibits excellent thermal stability and brings flexibility to sol-gel coating systems. In many sol-gel applications Dynasylan® 9165 is partially hydrolyzed to form a preproduct that can be further crosslinked using temperature. This pre-hydrolysis is often made in conjunction with alkyl silanes(Dynasylan® MTES)or other organofunctional silanes(Dynasylan® GLYMO), silicic acid esters, or even an aqueous silica sol. This pre-product can be further modified by addition or 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 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 heat resistant materials than using traditional resins. Phenyltrimethoxysilane. Used in sol-gel coating systems. Exhibits very good thermal stability and brings flexibility.
