Widely used as a precursor in sol-gel processes to produce titanium dioxide (TiO₂) coatings and nanoparticles. These materials are applied in photocatalysis, self-cleaning surfaces, anti-fogging films, sunscreens, and antibacterial coatings due to their photoactive properties.

It is also employed in the synthesis of hybrid organic-inorganic materials for optical and electronic applications.

In organic synthesis, it serves as a Lewis acid catalyst for esterification, transesterification, epoxidation, and condensation reactions.

Additionally, it functions as a crosslinking or coupling agent in coatings, adhesives, and composites, improving thermal and chemical resistance, and adhesion between inorganic surfaces (such as metal or glass) and polymers.

Its reactivity with water and alcohols makes it useful in surface modification of inorganic fillers and nanomaterials.

In the textile and paper industries, it is used to improve water repellency and the adhesion of dyes or coatings.
