Dynasylan® PTMO
Dynasylan® PTMO is a colourless, low-viscosity liquid. Dynasylan® PTMO is regarded as trifunctional since all three methoxy groups can hydrolyze. Dynasylan® PTMO also contains a propyl group that adds hydrophobic character to sol-gel coatings. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-). 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.
