Silane Adhesion Promoters Mechanism

Table of Content
Silane adhesion promoters mechanism is simple: With better interfacial bonds between dissimilar materials, the desirable properties of each component can be carried throughout a composite material.

Silane adhesion promoter is a molecule comprised of one central silicon atom with four attachments. These substituent groups can be nearly any combination of nonreactive, inorganically reactive, or organically reactive groups. Silanes are the smallest silicon-based molecules, ensuring good depth of penetration into substrates. A silane that contains at least one carbon silicon bond structure is known as an organosilane. In many applications, the term “silane” is a generic term typically referring to an organofunctional alkoxysilane. Here, the terms silane, alkoxysilane and organofunctional alkoxysilane are used interchangeably. Silane Adhesion Promoter Mechanism is to react with themselves and any hydroxyl (OH) groups within the substrate, often when moisture is present, forming a silicone resin network.
Water repellents and surface protection
Silanes can give water and stain-repellent properties to surfaces.
Plastics and composites
Silanes are critical to strength and durability of composites and can provide more effective coupling and dispersion treatments.
Paints, inks and coatings
The unique capabilities of silanes make them ideal for high-performance paints and coatings, as do their ability to withstand physical, chemical, environmental and thermal degradation.
Adhesives and sealants
Silanes are widely used to improve adhesion of a broad range of sealants and adhesives to inorganic substrates such as metals, glass and stone.
