1,8-Bis(triéthoxysilyl)octane

Description :

1,8-Bis(triéthoxysilyl)octane, avec le numéro CAS 52217-60-4, est un composé organosiliconé caractérisé par ses groupes fonctionnels de triéthoxysilyle doubles attachés à une structure d'octane. Cette structure confère des propriétés uniques, le rendant utile dans diverses applications, en particulier dans la modification de surfaces et comme agent de couplage dans les matériaux composites. Les groupes de triéthoxysilyle facilitent la liaison aux surfaces inorganiques, améliorant l'adhésion et la compatibilité entre les matériaux organiques et inorganiques. Ce composé est typiquement un liquide incolore à jaune pâle et est soluble dans des solvants organiques, tandis que ses groupes silanol peuvent subir une hydrolyse, entraînant la formation de réseaux de siloxane lors du durcissement. Sa capacité à améliorer les propriétés mécaniques et thermiques des composites le rend précieux dans des industries telles que la construction, l'électronique et les revêtements. De plus, sa faible volatilité et sa stabilité dans diverses conditions contribuent à son utilité dans des formulations nécessitant des performances durables et robustes. Les données de sécurité doivent être consultées pour les directives de manipulation et d'exposition, comme pour toute substance chimique.

Alkyl Silane - Dipodal 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.
Non Functional Alkoxy Silane
Silane coupling agents have the ability to form a durable bond between organic and inorganic materials to generate desired heterogeneous environments or to incorporate the bulk properties of different phases into a uniform composite structure. The general formula has two classes of functionality. The hydrolyzable group forms stable condensation products with siliceous surfaces and other oxides such as those of aluminum, zirconium, tin, titanium, and nickel. The organofunctional group alters the wetting or adhesion characteristics of the substrate, utilizes the substrate to catalyze chemical transformations at the heterogeneous interface, orders the interfacial region, or modifies its partition characteristics, and significantly effects the covalent bond between organic and inorganic materials.
Dipodal Silane
Dipodal silanes are a series of adhesion promoters that have intrinsic hydrolytic stabilities up to ~10,000 times greater than conventional silanes and are used in applications such as plastic optics, multilayer printed circuit boards and as adhesive primers for ferrous and nonferrous metals. They have the ability to form up to six bonds to a substrate compared to conventional silanes with the ability to form only three bonds to a substrate. Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability. Also known as bis-silanes additives enhance hydrolytic stability, which impacts on increased product shelf life, ensures better substrate bonding and also leads to improved mechanical properties in coatings as well as composite applications.
