Dynasylan® PTEO an alkyltrialkoxysilane is important component in solÂgel systems. Dynasylan® PTEO is a colorless, lowÂviscosity liquid. Dynasylan® PTEO is regarded as trifunctional since all three alkoxy groups can hydrolyze. Additionally Dynasylan® PTEO contains a propyl group that adds a hydrophobic character to the coatings. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (ÂSiÂOÂSiÂ). 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.
