Octyltriethoxysilane (OCTEO)

Octyltriethoxysilane is a functional organosilane coupling agent designed to enhance surface hydrophobicity and adhesion between organic polymers and inorganic substrates. The octyl group provides excellent water repellency, chemical resistance, and surface protection, while the ethoxy groups allow for strong bonding to mineral or glass surfaces through hydrolysis and condensation reactions.

This silane is commonly used in coatings, adhesives, sealants, and composite materials, where improved moisture resistance, durability, and surface performance are required. It is particularly effective for glass, metal, and mineral surface treatments.

Key Features:

• Improves hydrophobicity and moisture resistance

• Enhances adhesion between organic and inorganic materials

• Provides chemical and thermal stability

• Strengthens surface durability and performance in composites

Applications:

• Coatings and paints

• Adhesives and sealants

• Polymer and composite materials

• Glass, metal, and mineral surface treatments
