Octadecilmetildimetoxisilano

Descripción:

Octadecilmetildimetoxisilano, con el número CAS 71808-65-6, es un compuesto organosilícico caracterizado por su larga cadena alquílica hidrofóbica, que consta de 18 átomos de carbono. Esta estructura confiere propiedades hidrofóbicas significativas, lo que lo hace útil como modificador de superficie y agente de acoplamiento en diversas aplicaciones, incluyendo recubrimientos, adhesivos y selladores. La presencia de grupos dimetilo mejora su compatibilidad con materiales orgánicos, mientras que el grupo metoxi permite una posible reactividad con grupos silanol en superficies, facilitando el enlace. Típicamente, este compuesto aparece como un líquido incoloro a amarillo pálido y tiene una volatilidad relativamente baja. Sus aplicaciones se extienden a mejorar la repelencia al agua de las superficies, aumentar la durabilidad de los materiales y proporcionar propiedades anticorrosivas. Además, puede ser utilizado en la formulación de productos a base de silicona, donde contribuye al rendimiento y estabilidad general del producto final. Se deben consultar las hojas de datos de seguridad para obtener pautas sobre el manejo y almacenamiento, como con cualquier sustancia química.

Alkyl Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.

Methoxy(dimethyl)octadecylsilane

CAS: 71808-65-6

Methoxy(dimethyl)octadecylsilane is a silane cross-linking agent with a hydroxyl group. It is used in coatings, adhesives, and other polymeric matrices, as well as for the production of protonated methoxy groups. The hydroxyl group participates in the formation of hydrogen bonds and can form cross-links with other molecules in a solid phase microextraction process. Methoxy(dimethyl)octadecylsilane has been shown to be an effective corrosion inhibitor and to have growth factor activity. This compound is also capable of forming monolayers on the surface of cells that can be used for element analysis.
