Resumen
The invention defines a sol-gel coating applied to a substrate constituted by a polysiloxane network obtained from an organosilane compound comprising nanoparticles of titania embedded in the network and obtained in-situ from a titanium alkoxide, in which the titanium molar ratio: silicon is in the range of 1: 3 to 1: 5. This sol-gel coating has a lower thickness, acts as an effective protection barrier for the substrate against ultraviolet light and corrosión and also has better mechanical properties. Also, the invention defines a process for the preparation of said coating. (Machine-translation by Google Translate, not legally binding)
