Application Scope of Silane Coupling Agent

The application of silane coupling agentscan be roughly summarized as follows:

Surface treatment withsilane coupling agents

The adhesion performance of glass fibers and resins can be improved, greatly enhancing the strength, electrical, water and weather resistance properties of glass fiber reinforced composite materials. Even in the wet state, the improvement of mechanical properties of composite materials is also significant.

The use ofsilane coupling agentsin glass fiber is quite common. Silanecoupling agentsfor this purpose account for about 50% of their total consumption, with the most commonly used varieties being vinyl silane, amino silane, and methacryloxy silane.

Filling thermoplastics with silane coupling agents

The fillers can be pre-treated or added directly to the resin. This improves the dispersibility and bonding strength of the fillers in the resin, improves the compatibility between inorganic fillers and the resin, improves processing performance, and improves the mechanical, electrical, and weather resistance properties of the filled plastics (including rubber).

Silane coupling agents used as thickening agents for sealants, adhesives and coatings

This enhances their adhesion strength, water resistance, weather resistance and other properties. Silanecoupling agentscan often solve the long-standing problem of being unable to bond certain materials.

The principle of using silane coupling agents as thickening agents is that they have two functional groups: one can be combined with the skeleton material being bonded, and the other can be combined with the polymer material or adhesive, forming a strong chemical bond at the bonding interface, greatly improving the bonding strength.

Generally, there are three methods for the application ofsilane coupling agents: one is as a surface treatment agent for the skeleton material, the second is to add it to the adhesive, and the third is to directly add it to the polymer material. From the perspective of fully exerting its effectiveness and reducing costs, the first two methods are better.
