Ottadecilmetildimetossisilano

Descrizione:

Ottadecilmetildimetossisilano, con il numero CAS 71808-65-6, è un composto organosiliconico caratterizzato dalla sua lunga catena alchilica idrofobica, che consiste di 18 atomi di carbonio. Questa struttura conferisce proprietà idrofobiche significative, rendendolo utile come modificatore di superficie e agente accoppiatore in varie applicazioni, tra cui rivestimenti, adesivi e sigillanti. La presenza di gruppi dimetilici migliora la sua compatibilità con materiali organici, mentre il gruppo metossile consente una potenziale reattività con gruppi silanolo sulle superfici, facilitando il legame. Tipicamente, questo composto appare come un liquido incolore a giallo pallido e ha una volatilità relativamente bassa. Le sue applicazioni si estendono a migliorare la repellenza all'acqua delle superfici, aumentare la durabilità dei materiali e fornire proprietà anticorrosive. Inoltre, può essere utilizzato nella formulazione di prodotti a base di silicone, dove contribuisce alle prestazioni e alla stabilità complessiva del prodotto finale. Le schede di sicurezza devono essere consultate per le linee guida sul maneggio e lo stoccaggio, come per qualsiasi sostanza chimica.

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.
