Brief Uses and Applications of Aerosol 200 Fumed Silica (Grade – NV/200) in FRP / Composite Industry:

Aerosol 200 Fumed Silica (NV/200) is a high-purity, amorphous, hydrophilic fumed silica with a very high specific surface area. In the FRP (Fibre-Reinforced Plastic) / Composite industry, it plays a multifunctional role in improving product performance and processing efficiency.

Key Uses and Applications:
  1. Rheology Control / Thixotropy Agent:

    • Enhances viscosity and provides thixotropic properties in unsaturated polyester, epoxy, and vinyl ester resin systems.

    • Prevents resin sagging and settling during application, especially in vertical or overhead surfaces.

  2. Anti-Sagging and Anti-Settling Agent:

    • Prevents filler and pigment sedimentation in composite pastes, ensuring uniform consistency.

  3. Reinforcing Agent:

    • Improves mechanical properties like tensile strength, impact resistance, and elongation in cured composites.

    • Enhances surface hardness and durability.

  4. Resin System Stabilization:

    • Provides better control of flow and curing behavior in resin-rich areas.

    • Stabilizes formulations for storage and processing.

  5. Improved Surface Finish:

    • Contributes to a smoother, defect-free finish in molded FRP parts by minimizing resin shrinkage and surface imperfections.

  6. Enhanced Bonding Strength:

    • Improves adhesion between matrix resin and glass or carbon fibers in composite laminates.

  7. Lightweight Filler:

    • Acts as a low-density filler, aiding in the reduction of overall component weight without sacrificing strength.

  8. Used in Gel Coats and Putties:

    • Provides stability and uniformity in FRP gel coats, topcoats, and surface putties.

Typical Applications in FRP/Composites:
  • Boat hulls, panels, and automotive body parts

  • Windmill blades and aerospace components

  • Pipes, tanks, and chemical storage vessels

  • Sports equipment and consumer goods
