Dimetildietoxisilano

Descripción:

Dimetildietoxisilano, con el número CAS 78-62-6, es un compuesto organosilícico caracterizado por su estructura de silano, que incluye dos grupos etóxido y dos grupos metilo unidos a un átomo de silicio. Este compuesto es típicamente un líquido incoloro con un olor suave y es conocido por su reactividad, particularmente en la hidrólisis, donde puede formar grupos silanol y posteriormente polimerizar para crear redes de siloxano. Es soluble en disolventes orgánicos y exhibe baja volatilidad, lo que lo hace útil en diversas aplicaciones, incluyendo como agente de acoplamiento, modificador de superficie y en la formulación de materiales a base de silicona. Dimetildietoxisilano también se utiliza en la producción de recubrimientos, adhesivos y selladores debido a su capacidad para mejorar la adhesión y mejorar la resistencia al agua. Las consideraciones de seguridad incluyen manejarlo en áreas bien ventiladas y usar el equipo de protección personal adecuado, ya que puede causar irritación en la piel y los ojos. En general, sus propiedades químicas únicas lo hacen valioso tanto en entornos industriales como de investigación.

Diethoxydimethylsilane, 97%

CAS: 78-62-6

Diethoxydimethylsilane is useful for blocking hydroxyl and amino groups in organic synthesis reactions. This silylating step allows subsequent reactions to be carried out which would be adversely affected by the presence of active hydrogen in the hydroxyl or amine groups. Following the reaction step

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.
