SURFACE MODIFICATION
Post-Modification Advantages
Comprehensive performance improvement from surface activation treatment

🧪 Why Surface Modification?

The surface of silica powder raw material has strong polarity, making it difficult to disperse uniformly in organic polymer matrices. Issues such as agglomeration, high oil absorption, and poor matrix compatibility are common. Through surface activation modification treatment, an organic coating layer forms on the particle surface, providing good affinity with epoxy resin and organosilicon resin, enabling maximum high filling effect without affecting performance.

🧠
Significantly Reduced Polarity
Surface organic coating shields active groups, significantly reducing polarity
🌊
Improved Dispersibility
Effectively prevents particle agglomeration, enabling uniform distribution in organic matrices
💧
High Filling, Low Viscosity
Effectively controls system viscosity at high filling ratios, good processability
🤝
Strong Interfacial Bonding
Tight bonding with epoxy/organosilicon resin, mechanical properties retained
⚡
Excellent Fluidity
Particle edges passivated, regular shape, better fluidity
