Paints & Coatings

Fumed silica is added into painting and coatings for rheological control. It can effectively prevent sedimentation and delamination of pigments, improve the weather ability and scratch-resistance of coatings, and improve the bonding strength between coatings and substrates.

  • In-wall coatings of fumed silica helps to prevent the paint from flowing down and to improve the smoothness of the wall surface. What’s more, it can greatly improve the scratch resistance and aging time of the exterior wall coating, and also the bonding strength between the coating film and the wall, the hardness of the coating film and the surface self-cleaning ability
  • When fumed silica is adsorbed by powder coatings, a movable layer is formed on its surface. It improves flowing property by preventing powder coatings from absorbing moisture and agglomerating.
  • The main function of fumed silica in floor paint is to improve its ability of weather resistance, scratch resistance and leveling performance.
Types of Paints/ CoatingFunctions of Fumed Silica
Protective CoatingsImprove adhesion and corrosion resistance 
Inorganic CoatingImprove fire resistance, increase scrub resistance and coating film strength
Flame retardant PaintImprove strength, abrasion resistance, flame retardancy and weather resistance of the topcoat paint, increase service life
Anti-radiation CoatingEnhance the electromagnetic wave absorption function of the coating
Superhydrophobic finishing PaintEffectively improve the super hydrophobic ability and hardness of the coating film
Ceramic CoatingsImprove abrasion resistance, adhesion and hydrophobicity
Epoxy phenolic anticorrosive PaintsImprove mechanical properties & heat conduction, and extend the service life
Thermal barrier CoatingGood heat preservation and pore-forming effect
Quick-drying wall PaintImprove drying speed, anti-sagging, coating film hardness, scratch resistance and good weather resistance
Powder Coatings Avoid caking issues, improve flowing ability & storage stability
Multi-color PaintImprove the hydrophobicity, scrub resistance and weather resistance

What benefits you can get for your paint or coatings product by adding fumed silica?

  • Effectively avoid sedimentation;
  • prevent sagging and thick edges in the construction process;
  • Anti-caking, improve flowing performance for powder coatings;
  • improve weathering ability and scratch resistance;
  • improve bonding strength between coatings and substrates.
