Is your epoxy adhesive too runny? Sagging on vertical surfaces? Our latest experiment reveals the key to perfect consistency: HIFULL® Fumed Silica.
We tested three different formulations:
◾ Sample 1: 1.6% Fumed Silica
◾ Sample 2: 3.0% Fumed Silica
◾ Sample 3: 4.6% Fumed Silica
The rotational rheometer data clearly shows:
✅ Viscosity increases significantly with higher silica content.
✅ Thixotropy is dramatically enhanced.
The result? Sample 3 (4.6%) showed the highest viscosity and thixotropic value, making it ideal for applications where sag resistance and structural stability are critical.
Key takeaway: Within a certain range, increasing the fumed silica content is an extremely effective method to boost the viscosity and thixotropy of epoxy adhesives.
