AIRG‑S Aerogel Slurry / Paste
Dust‑free, water‑borne dispersion of hydrophobic silica aerogel particles that dries to an ultra‑low‑k, lightweight, and
water‑repellent coating or composite filler.
Key metrics:
• Core material: hydrophobic SiO₂ aerogel
• Slurry medium: water (proprietary dispersion)
• Dried thermal conductivity: 0.018 W m⁻¹ K⁻¹ (23 °C)
• Dry density: ≈ 60 kg m⁻³
• Restored contact angle on drying: > 150 °
• Recommended loading in formulations: 5 - 15 wt %
• Service temperature (dried layer): up to ≈ 800 °C in battery‑fire barrier tests
Why choose AIRG‑S?
• Dust‑free handling-eliminates the airborne particulate issues common to powdered aerogels
• Pure‑aerogel thermal performance at half the weight of conventional fillers

• Self‑restoring hydrophobicity: stable as an aqueous slurry, yet regains super‑hydrophobic behaviour after drying
• Water‑based & eco‑friendly: straightforward transport, mixing, and clean‑up
• Formulation flexibility: readily blends into water‑borne paints, plasters, foams, and paper/film stocks
• Technical backup: custom rheology, particle sizing, and performance data available on request
Typical applications
• Thermal‑barrier paints & renders: water‑borne façade or roof coatings with > 30 % HVAC energy savings
• Ultrathin building insulation layers: 1 mm dried film delivers the R‑value of a ~5 mm conventional layer
• Composite panels with perlite, rock wool, or fibreglass: 40 % lower λ while cutting panel weight
• EV battery pack and electronics modules: 0.5 mm fire‑protection coating sustaining 800 °C excursions
• Lightweight, fire‑resistant insulation papers and pipe wraps: asbestos‑free, higher compressive strength
• High‑reflectance (≥ 90 %) roof or tank topcoats for solar‑gain mitigation
