Octiltrietoxisilano

Descrição:

Octiltrietoxisilano, com o número CAS 2943-75-1, é um composto organossilícico caracterizado por sua estrutura de silano, que inclui um grupo octílico e três grupos etóxido ligados a um átomo de silício. Este composto é tipicamente um líquido incolor a amarelo pálido e é conhecido por suas propriedades hidrofóbicas, tornando-o útil como modificador de superfície e agente de acoplamento. Octiltrietoxisilano pode melhorar a adesão de materiais orgânicos a substratos inorgânicos, como vidro e metais, formando uma ligação siloxano após hidrólise e condensação. É frequentemente empregado em aplicações como revestimentos, selantes e adesivos, onde se deseja melhor repelência à água e durabilidade. Além disso, pode ser usado na formulação de materiais à base de silicone e como precursor na síntese de nanopartículas de sílica. Considerações de segurança incluem manuseá-lo em áreas bem ventiladas e usar equipamentos de proteção individual adequados, pois pode ser irritante para a pele e os olhos.

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.
