Southern Ag Surfactant

Surface treatment
It can improve the bonding performance between glass fiber and resin, greatly improve the strength, electrical, water resistance, and weather resistance of glass fiber reinforced composite materials. Even in wet state, it has a significant effect on improving the mechanical properties of composite materials. The use of silane coupling agents in glass fiber is quite common, and the silane coupling agents used in this aspect account for about 50% of its total consumption. Among them, the most commonly used varieties are vinyl silane, amino silane, methacryloxy silane, etc.

Filled plastics
The filler can be surface treated in advance or directly added to the resin. It can improve the dispersibility and adhesion of the filler in the resin, improve the compatibility between inorganic fillers and resins, improve process performance, and improve the mechanical, electrical, and weather resistance of filled plastics (including rubber).

Used as a tackifier for sealants, adhesives, and coatings
It can improve their bonding strength, water resistance, and weather resistance. Silane coupling agents can often solve the problem that some materials have long been unable to bond. The principle of silane coupling agent as a tackifier is that it has two groups; one group can combine with the bonded skeleton material; and the other group can combine with the polymer material or adhesive, thereby forming a strong chemical bond at the bonding interface, greatly improving the bonding strength. There are generally three ways to apply silane coupling agent: one is as a surface treatment agent for skeleton materials; the second is to add it to the adhesive; the third is to add it directly to the polymer material. From the perspective of giving full play to its effectiveness and reducing costs, the first two methods are better.
