Used as a coupling agent to improve adhesion between organic and inorganic materials, especially in sealants, coatings, paints, printing inks, and adhesives. Enhances water repellency, moisture resistance, and durability in construction materials like concrete and stone.

Commonly applied in the formulation of water-based systems due to good hydrolytic stability. Also utilized in the treatment of glass, mineral, metal, and ceramic surfaces to promote bonding with polymers and improve corrosion resistance.

In the plastics and rubber industries, it acts as a dispersant and improves mechanical properties of composites. Additionally, it serves as a precursor in the synthesis of high molecular weight silicones and in water-resistant skincare products.
