Bis(triethoxysilyl)ethylene

Description:

Bis(triethoxysilyl)ethylene, with the CAS number 87061-56-1, is an organosilicon compound characterized by its dual triethoxysilyl functional groups attached to an ethylene backbone. This structure allows it to act as a silane coupling agent, enhancing adhesion between organic materials and inorganic substrates, such as glass or metals. The triethoxysilyl groups are hydrolyzable, enabling the compound to form siloxane bonds upon exposure to moisture, which is beneficial for creating durable coatings and sealants. Bis(triethoxysilyl)ethylene is typically a colorless to pale yellow liquid, exhibiting low volatility and good thermal stability. It is soluble in organic solvents and can be used in various applications, including surface modification, composite materials, and as a crosslinking agent in polymer formulations. Its ability to improve mechanical properties and resistance to environmental factors makes it valuable in industries such as construction, automotive, and electronics. Safety precautions should be observed when handling this compound, as it may cause irritation upon contact with skin or eyes.

Olefin 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. Dipodal 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.
