1、Silane coupling agent as bridge to assist in preparing high

In the paper, the silane coupling agent γ-aminopropyltriethoxysilane (KH550) was used to treat the surface of anodized aluminum alloy. Then the treated Al was joint with PBT, and the schematic diagram of chemical bonding coupling is shown in Fig. 1.

2、Silane Coupling Agents

Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.

3、Limitless silanes

A silane coupling agent will act as an interface between an inorganic substrate (such as glass, metal or mineral) and an organic material (such as an organic polymer, coating or adhesive) to bond the two dissimilar materials.

4、Silane Coupling Agent

There are three basic approaches for using silane coupling agents. The silane can be used to treat the surface of the inorganic materials before mixing with the organic resin or it can be added directly to the organic resin or holistic mixing (in organic-inorganic mixture).

This paper presents the efects of silane coupling agent, which includes interfacial adhesive strength, water treatment, polymer composites and coatings that make it valuable for multi-materialization.

Silane coupling agent in biomedical materials

The silane coupling agent is able to form a durable bond between organic and inorganic materials. The dehydration process provides linking sites to achieve condensation of two hydroxyl groups. The forming covalent bond brings excellent mechanical properties among different surfaces.

The Use and Method of Silane Coupling Agent

In actual use, the coupling agent often forms a stacked layer on the surface, but only a single molecular layer actually works, so the amount of the coupling agent does not need to be too much.

Silane Coupling Agent

The two groups on the silane binding agent molecule diffuse to the surface with equal polarity, with one end oriented to the surface of inorganic materials and the other end oriented to the surface of organic materials, thereby completing the coupling process between inorganic and organic materials.
