Adhesion Promoters: Silane Coupling Agents
1、Adhesion Promoters: Silane Coupling Agents
The unique nature of silane chemistry to have both inorganic and organic reactivity in one molecular structure gives rise to the use of silane chemicals as coupling agents and adhesion promoters.
2、Silane Coupling Agents as Adhesion Promoters for Aerospace Structural Film Adhesives: The Journal of Adhesion: Vol 22, No 3
The performance of eight organofunctional silane coupling agents as adhesion promoters for the bonding of aluminium with two 121°C and two 177°C curing structural film adhesives was investigated and compared to the chromic acid (FPL) etch pre-treatment process and two non-chemical pretreatments.
3、Use of silanes and copolymers as adhesion promoters in glass fiber/polyethylene composites
Abstract Two organofunctional silanes and three functionalized copolymers were used as adhesion promoters in glass fiber/polyethylene-reinforced composites. The performance of the coupling agents was investigated by mechanical property measurements, scanning electron microscopy, and dynamic mechanical analysis.
4、Role of Silanes in Polymer
Organofunctional silanes are generally recommended as “coupling agents” in bonding organic polymers to mineral substrates. Certain silane primers that are effective in bonding two dissimilar polymers to glass are also effective in bonding the two polymers to each other.
Bonding dissimilar polymer networks in various manufacturing processes
Here the authors mix silane coupling agents into a precursor to form hydrogel resins with robust properties that can be spun, coated and printed in air.
Silanes as Primers and Adhesion Promoters for Metal Substrates
In addition to coatings and adhesives, silanes have multiple commercial uses, such as coupling agents for reinforced plastics, crosslinking agents for polyethylene cables, and dispersants for paints and printing inks.
Silane coupling agents: the role of the organofunctional group: Journal of Adhesion Science and Technology: Vol 5, No 10
Some highlights of recent research on silane coupling agents are reviewed. Studies of silanes in solution, of chemical bonding in the substrate/matrix interphase, and of the interfacial bond in composites have provided new insights into the mechanism of effectiveness of silane adhesion promoters.
Synthesis of UV
In order to solve this problem, a new UV-curable silane-coupling agent (UV-SCA) was synthesized to be an adhesion promoter, which was synthesized by the reaction between the hydroxyl group of bisphenol A epoxy diacrylate and the isocyanate group of 3- (isocyanatopropyl)-triethoxysilane.
The Role of Silane Coupling Agents and Universal Primers in Durable Adhesion to Dental Restorative Materials
One example of chemical adhesion utilizes primers or bonding agents containing coupling agents. Universal primers which are (mainly organophosphate-based monomers) and silane coupling agents are the most effective and most widely used for unifying dissimilar materials.

The coupling agents under-went changes in orientation in the adsorbed state with increasing surface coverage. These changes could also be induced by co-adsorbates.
