Silane coupling agents are used in adhesives, coatings
Silane coupling agents are used in adhesives, coatings, and composite materials to promote bonding between inorganic and organic materials. They also serve as surface treatments for minerals in plastics.
The selection of silane coupling agents depends on the chemical properties of the substrate. Choosing a silane that matches well with the polymer system helps to reduce interactions between the two. For reinforced plastics, the suitable type of silane can be determined by the properties of the polymer.
Epoxy silanes are bifunctional silanes that can be used to promote bonding between organic polymers. Typically, epoxy silanes contain reactive epoxy groups. These compounds form strong, non-yellowing adhesion to inorganic and organic surfaces.
Using silanes as adhesion promoters has been proven effective in various applications, including bonding, coating technologies, and hull laminates.
In addition to their function as adhesion promoters, silanes can also be used as primers and dispersion aids. Primer formulations typically consist of an alcohol-diluted solution of 0.5% to 5% silane. It is wiped or sprayed onto the substrate to increase initial adhesion.
Silane coupling agents are an important component used to enhance the bonding between two polymers and can also promote adhesion.
