Pre-treatment method of silane coupling agent for filler

The filler is placed in a solid mixer and the above silane solution is sprayed directly onto the filler and stirred. The higher the stirring speed, the better the dispersion effect. Generally, the stirring time is 10-30 minutes (the slower the speed, the longer the time). After the filler treatment, it should be dried at 120°C for 2 hours.

Silane coupling agents have good chemical stability, low surface energy, good wettability and strong adhesion,
