Fusyl Series – High-Performance Fumed Silica

Fusyl Series – High-Performance Fumed Silica

The Fusyl Series represents 20 Microns’ advanced range of fumed silica (pyrogenic silica) designed for superior performance in paints, coatings, and specialty applications. Produced through flame hydrolysis, Fusyl fumed silica is a non-crystalline, high-purity colloidal silicon dioxide. Its unique three-dimensional network of ultra-fine nanoparticles provides an exceptionally large surface area, making it highly effective as a rheology modifier, thickener, anti-sagging agent, and reinforcement additive.

Appearing as a white, fluffy powder, Fusyl fumed silica enhances stability, transparency, and mechanical strength across diverse formulations — from industrial paints and protective coatings to powder coatings and epoxy systems.

FUSYL T72 Silane modified, moderate surface area Controlled rheology, balanced matting
FUSYL T74 Silane modified, high surface area Maximum thickening & reinforcement

Frequently Asked Questions (FAQs)

Q1. What is fumed silica?

A: A nano-sized silica powder used as a thickener, anti-sagging, and rheology modifier.

Q2. Hydrophilic vs Hydrophobic fumed silica – what’s the difference?

A: Hydrophilic works in water-based systems; hydrophobic offers water resistance in solvent systems.

Q3. How does it improve paints?

A: Prevents sagging, settling, and improves stability and finish.

Q4. Where is it used?

A: Paints, coatings, adhesives, sealants, and construction materials.

Q5. How to select the right grade?

A: Choose based on system polarity and required effect (thickening, matting, stability).
