Product Highlights: Acrylate Functional Trialkoxy 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.

Technical Details & Test Data

SAMs (Self-Assembled Monolayers): They can be applied neat or in solution via conventional lithography techniques to form SAMs. SAM is a layer of amphiphilic molecules created by the chemisorption onto a metal oxide, precious metal surface, plastic or nanoparticle substrates, followed by the 2-dimensional alignment of hydrophobic groups to form a structures single monolayer. The surface can be selectively modified to achieve the desired antisticktion, mechanical and chemical properties for microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS).
Test Data: How do activated silanes work? (Mechanism and Chemistry)

The reaction of activated silanes is driven by the thermodynamically favored formation of a silicon-oxygen bond, and is >85% complete in less than 15 seconds, reacting with more than three times as many hydroxyl groups as the conventional ethoxysilane achieve in 1 hour. Once the ring is opened, the secondary amine promotes the condensation of silanols formed from the base silane component with the substrate, more than doubling the kinetics of reactivity for hydrolytic deposition.
