AIRG‑S Aerogel Slurry
Dust‑free, water‑based SiO₂ aerogel dispersion for spray‑on or roll‑on thermal‑insulation coatings.
Key metrics
Thermal conductivity (dry film): 0.018 W m⁻¹ K⁻¹ @ 25 °C (ASTM C177)
Bulk density (dry): ≈ 60 kg m⁻³
Contact angle (restored): > 150 °
Solids content: 25 ± 2 wt %
Why AIRG‑S?
Dust‑free handling – eliminates airborne silica during mixing or spraying.
One‑step hydrophobic recovery – slurry is stable in water; films become water‑repellent after curing.
Ultra‑lightweight – cuts coating weight by 50 % versus acrylic hollow‑glass‑bead systems.
Versatile formulation window – compatible with acrylic, silicate and PU water‑borne binders at 5‑15 phr.
Typical applications
| Sector | Use case | Benefit |
|---|---|---|
| Architectural coatings | Exterior cool‑roof paints | ↓ 30 % HVAC load, emissivity 0.90 |
| Prefabricated panels | Aerogel‑perlite composites | λ ≤ 0.022 W m⁻¹ K⁻¹ at 10 mm |
| EV battery packs | 0.5 mm inner‑lid coating | Delays thermal runaway ≥ 10 min (UL 9540A test data) |
| Industrial pipes | Spray‑applied wrap | Same R‑value as 5 mm mineral wool in 1 mm dry film |
