HS-200 Fumed Silica
High-purity HS-200 Fumed Silica (10kg) is a professional-grade thickening agent designed to increase the viscosity and thixotropy of resins, gelcoats, and paints. Essential for creating non-sagging mixtures, structural adhesives, and high-stability fillers in the marine and composite industries.
HS-200 Fumed Silica is an ultra-fine, high-surface-area silica powder used as a universal thixotropic agent. This 10kg industrial format is designed for large-scale production, shipyards, and professional workshops.
When added to liquid polyester, epoxy, or vinylester resins, HS-200 creates a sophisticated rheological structure. This allows the resin to remain fluid while being stirred or applied (shear-thinning) but “lock” into place once the movement stops, preventing drips and sagging on vertical or overhead surfaces. It also acts as a powerful anti-settling agent for pigments and fillers, ensuring a homogeneous mixture throughout the curing process.
✔ Maximum Thixotropy → Prevents resin runoff and sagging on vertical surfaces.
✔ High Purity (99.8%+) → Does not alter the chemical properties or color of the base resin.
✔ Structural Reinforcement → Improves the mechanical strength and hardness of the final composite.
✔ Anti-Settling Properties → Keeps pigments and other fillers suspended for a uniform finish.
✔ Excellent Dispersibility → Blends easily into liquid systems with standard mixing equipment.
Type: Hydrophilic Fumed Silica
Grade: HS-200
Specific Surface Area (BET): 200 ± 20 m²/g
Appearance: Ultra-fine, lightweight white powder
Format: 10 kg Industrial Bag
Compatibility: Epoxy, Polyester, Vinylester resins, Gelcoats, and Enamels.
🔹 Application Instructions
Safety First: This powder is extremely light and volatile. Always wear a dust mask (P2/P3) and work in a draft-free area.
Mix your resin and catalyst/hardener first.
Gradually add HS-200 while stirring slowly to avoid creating a dust cloud.
Recommended Dosage: – Anti-settling/Slight thickening: 0.5% – 1.0% by weight.
Thixotropic/Non-sag: 2.0% – 3.0% by weight.
Structural Adhesives: Up to 5% or more until the desired “peanut butter” consistency is reached.
👉 Pro Tip: For a superior fairing compound, combine HS-200 with Microcel (Glass Microballoons). The silica provides the anti-sag properties, while the microballoons make the mixture lightweight and easy to sand.
Marine Construction: Formulating non-sag gelcoats and structural bonding pastes for hulls and decks.
Structural Adhesives: Creating high-strength glues for fiberglass, wood, and metal.
Industrial Coatings: Improving the flow and stability of high-performance paints and varnishes.
Composites: Adjusting the viscosity of laminating resins for complex vertical molds.
Industrial Bag: 10 kg (Note: Due to its extremely low density, a 10kg bag is very high in volume).
Stable, high-viscosity resin systems that stay exactly where applied, ensuring professional structural bonds and a perfect finish on any surface angle.
