Silane coupling agents still work without hydrolysis, but their effects and application scenarios will be different.

1. Mechanism of action:
Silane coupling agents react with inorganic and organic surface groups through their chemically active groups to form strong chemical bonds, thereby improving the bonding force between materials9.

2. Application without hydrolysis:
Direct use: When some silane coupling agents are directly added to coatings, adhesives and other systems, they can work directly without hydrolysis to form a layer of transparent silane film, improving the texture treatment effect of the metal surface.

3. Stability under specific conditions:
Some silane coupling agents can remain stable under specific conditions (such as strong acid and strong base systems) and can be used without hydrolysis.

4. The role of hydrolysis:
Improve dispersibility: Silane coupling agents usually need to be hydrolyzed to expose their silanol groups, thereby improving their dispersibility in aqueous solutions, allowing them to be evenly dispersed and evenly act on the surface of the material.

5. Enhanced bonding strength:
The hydrolyzed silane coupling agent can better combine with inorganic materials such as metals, improve the bonding strength between the coating and the metal substrate, and enhance the corrosion resistance of the coating.

6. Practical application suggestions:
Choose according to needs: Choose whether to hydrolyze the silane coupling agent according to the specific application needs. If you need to improve dispersibility and bonding strength, hydrolysis treatment is usually required.

7. Control dosage:
Regardless of whether it is hydrolyzed or not, the dosage of silane coupling agent needs to be strictly controlled to ensure its best effect and avoid adverse effects caused by excessive use.

In summary, silane coupling agents still have effects without hydrolysis, but their effects and application scenarios will be different. Choose whether to hydrolyze according to specific needs, and strictly control the dosage to achieve the best application effect.
