Long-Chain Alkyl Silanes

Long chain silanes are silane compounds containing long alkyl chains. These silanes exhibit high hydrophobicity, wettability and dispersibility, as well as heat and weather resistance. These features enable them to function admirably in a wide range of applications, including waterproofing treatment, building protection, and surface modification of fillers and nanoparticles.

ChangFu Chemical provides a range of specialty silanes with long alkyl chains, such as C6, C8, C12, C16, and C18 silanes. The hydrophobic functional group of these silanes gives them distinct surface modification properties. As a result, these silane monomers have been used to modify and functionalize the surfaces of inorganic powders and fillers.

Uses of Long-Chain Alkyl Silanes

1. Surface Modification

Hydrophobic Coatings: Used to impart water-repellent properties to surfaces, including glass, metal, and ceramics.

Self-Cleaning Surfaces: Enhance the self-cleaning properties of surfaces by reducing the adhesion of dirt and contaminants.

Chromatography Columns: Used in various types of chromatography columns, such as GC Columns, HPLC Columns, primarily to enhance separation performance.

2. Adhesives and Sealants

Adhesion Promotion: Enhance the bonding between organic polymers and inorganic substrates, increasing the effectiveness of adhesives and sealants.

Enhanced Protection: Provide resistance to water and chemicals, increasing the adhesive's effectiveness in harsh environments.

Improved Performance: Improve the overall performance of sealants and adhesives, making them suitable for a wider range of applications and substrates.

3. Chemical Synthesis

Precursor for Polymers: Act as intermediates in the synthesis of silicone polymers and other organic-inorganic hybrid materials.

Catalysis and Chemical Reactions: Introduce hydrophobic functional groups into chemical compounds, enhancing their properties or reactivity in various reactions.

Pharmaceutical and Biomedical Applications: Used in the development of drug delivery systems and medical devices to improve biocompatibility and surface interactions.

Properties of Long-Chain Alkyl Silanes

ChangFu long-chain alkyl silanes have several distinctive properties that make them useful in various applications:

Hydrophobicity:

Non-Polar Nature: The long alkyl chains (such as C12, C18) impart significant hydrophobic properties, making these silanes repel water and oils.

Chemical Reactivity:

Silane Groups: Contains reactive silane groups (like chlorosilane or alkoxysilane) that can form bonds with various substrates, enabling surface modification and chemical bonding.

Surface Affinity:

Enhanced Adhesion: They form strong bonds with inorganic surfaces (e.g., glass, metals) and organic materials, improving adhesion and coating performance.

Durability:

Weather and Chemical Resistance: Enhance the resistance of treated surfaces to environmental factors such as UV radiation, moisture, and chemicals.

Stability:

Thermal and Chemical Stability: Generally stable under normal conditions but can undergo hydrolysis in the presence of moisture, which forms silanol groups and eventually siloxane bonds.
