Also known as pyrogenic silica, it consists of microscopic droplets of amorphous silica fused into branched, chainlike. 

Pre-dispersed fumed silica is an aqueous dispersion of hydrophobic fumed silica mainly used in water-based pigmented coatings and clear coatings. They provide good rheology control, anti-settling, pigment stabilization and improvement of mechanical properties.

This technology is suitable for applications of high-performance waterborne industrial coatings, such as plastic, metal, and automotive coatings.

Benefits:

• Ease of handling
• No dusting or worker exposure to dust particles
• Less energy to incorporate
