Alkylalkoxysilanes are combined used together with Ethyl Silicates, particularly methyltrialkoxysilane, propyltrialkoxysilane. Long carbon chain silanes maybe added to in the formulation to improve hydrobic properties.
Phenylsilanes can improve the thermal stability of the coating.
Additional hydrophobic and oleophobic effects can be achieved by modifying the sols with small proportions of a fluoroalkylsilane.
Amino silanes can be used as wetting agents in sol-gel systems.The use of aminosilanes usually results in basic sols, which can be cured at room temperature while taking advantage of humid conditions.
