Properties and Usage:

Octyltriethoxysilane is an organic silicon compound belonging to the alkylsilane category. It has hydrophobic and low surface energy properties and is widely used in coatings, building materials, and surface treatment. The following is an overview of its properties and applications:

Applications:

1. Building and waterproof materials:

Waterproofing agent: Triethoxyoctylsilane is often used for waterproofing of building materials such as concrete, stone, and bricks. It can form a hydrophobic protective film on the surface of these materials, effectively preventing moisture penetration and extending the service life of the building. Octyltriethoxysilane can effectively treat the surface of inorganic materials such as glass, metal, and ceramics. It significantly improves the water resistance, UV resistance, and corrosion resistance of the material by forming a stable chemical bond with the surface of the material.

Surface treatment agent: In the surface treatment process of building materials, Triethoxyoctylsilane can be used as a surface modifier to make it have better stain resistance and corrosion resistance.

2. Coatings and inks:

Hydrophobic additives: This compound can be used as a hydrophobic additive and added to coatings, inks and sealants to improve their waterproof and antifouling properties, while increasing the durability and adhesion of the product.

3. Preparation of silicone materials:

Silicone polymers: n-Octyltriethoxysilane can be used to prepare silicone polymers and copolymers, which are widely used in adhesives, sealants and elastomers, and have elasticity and weather resistance.

4. Other industrial applications:

Coupling agent: As a coupling agent, n-Octyltriethoxysilane can be used to improve the compatibility between inorganic fillers and organic substrates and improve the mechanical properties of composite materials.

Storage conditions: Sealed in a cool and dry environment

Packing: This product is packed in 25kg 180kg drums, and it can also be customized according to customers' requirements
