Application
Hexadecyltrimethoxysilane can be used as:
- A hydrophobic modifier to modify silica nanoparticles, enabling the creation of superhydrophobic particles and composites, which are ideal for applications in coatings and textiles.
- A key component in the fabrication of durable, fluorine-free superhydrophobic coatings by modifying halloysite nanotubes embedded in silicone-acrylic polymer films.
- An additive in the development of hydrophobic aerogels based on nanocellulose, where HDTMS contributes to the creation of materials with high oil adsorption capacities.
Features and Benefits
- Thermally Stable: Suitable for high-temperature applications and thermal curing processes.
- Moisture-Sensitive: Hydrolyzes in the presence of water to form reactive silanol groups that bond covalently to surfaces.
- Long Alkyl Chain: Provides excellent surface hydrophobicity due to its high surface energy barrier.
Storage Class
