Octadecilmetildimetoxisilano

Descrição:
Octadecilmetildimetoxisilano, com o número CAS 71808-65-6, é um composto organossilícico caracterizado por sua longa cadeia alquílica hidrofóbica, que consiste em 18 átomos de carbono. Essa estrutura confere propriedades hidrofóbicas significativas, tornando-o útil como modificador de superfície e agente de acoplamento em várias aplicações, incluindo revestimentos, adesivos e selantes. A presença de grupos dimetila melhora sua compatibilidade com materiais orgânicos, enquanto o grupo metóxi permite uma reatividade potencial com grupos silanol em superfícies, facilitando a ligação. Normalmente, este composto aparece como um líquido incolor a amarelo pálido e tem uma volatilidade relativamente baixa. Suas aplicações se estendem a melhorar a repelência à água de superfícies, aumentar a durabilidade dos materiais e fornecer propriedades anticorrosivas. Além disso, pode ser utilizado na formulação de produtos à base de silicone, onde contribui para o desempenho e estabilidade geral do produto final. As fichas de dados de segurança devem ser consultadas para diretrizes de manuseio e armazenamento, assim como com qualquer substância química.

  • n-OCTADECYLDIMETHYLMETHOXYSILANE

    CAS:
    <p>Alkyl Silane - Conventional Surface Bonding<br>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.<br>n-Octadecyldimethylmethoxysilane; Methoxydimethyloctadecylsilane; Dimethylmethoxysilyloctadecane<br>Contains 5-10% C18 isomersEmployed in SAM resistMonoalkoxy silane<br></p>

  • Methoxy(dimethyl)octadecylsilane

    CAS:
    <p>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.</p>
