SPHERILEX® DP-0117 is a precipitated amorphous (crystalline-free) silica with uniquely spherical particle shape and very narrow particle size distribution.

Dynasylan® MTMS an alkyltrialkoxysilane is an important component in sol­gel systems. Dynasylan® MTMS is a colorless, low­viscosity liquid. Dynasylan® MTMS is regarded as trifunctional since all three alkoxy groups are able to hydrolyze. Additionally Dynasylan® MTMS contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (­Si­O­Si­). 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.

Dynasylan® PTEO an alkyltrialkoxysilane is important component in sol­gel systems. Dynasylan® PTEO is a colorless, low­viscosity 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 (­Si­O­Si­). 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.
