Product Features:
- Cooling & Energy Saving:At summer noon, substrate surface temperature drops 15–20°C, indoor temperature drops 5–10°C. Air conditioning energy savings of 30%–50%, significantly reducing cooling energy consumption.
- Passive & Eco-friendly:Water-based eco-friendly coating, requires no electricity or refrigerants, zero energy consumption, zero emissions, mitigates urban heat island effect.
- Durable & Reliable:Flexible coating, crack and peel resistant; aging and rain erosion resistant; compatible with metals, concrete, color steel sheets, and other substrates.
- Easy Application:Roll, spray, or brush; no complex pretreatment required, can be applied directly on old roofs/exterior walls.
- Multi-functional:Provides insulation, reflection, radiative cooling, waterproofing, corrosion resistance, and decorative functions in one coating.
Design Purpose:
Aerogel Radiative Cooling Coating is a water-based eco-friendly functional coating. Its core insulating component is nano-aerogel, combined with high solar reflective fillers, high infrared emissive materials, and environmentally friendly film-forming systems. It achieves passive cooling by reflecting solar heat, radiating heat into outer space, and blocking thermal conduction.
- Solar Heat Reflection:Reflectance of solar light (visible + near-infrared) ≥85%, up to 90%, reducing over 90% of solar heat absorption.
- Radiative Cooling:In the 8–13.5μm atmospheric window, hemispherical emissivity ≥0.90, directing absorbed heat as far-infrared radiation into outer space for “active” heat dissipation.
- Ultra-low Thermal Conductivity:Aerogel’s 3D nanoporous structure provides ultra-low thermal conductivity, blocking heat transfer, with 3–5 times better insulation than conventional materials.

Procedure:
- Open and stir: check for stratification, stir evenly (>1 min), avoid high-speed dispersion.
- Apply coating by spraying 1–5 layers, thickness based on environment, area, quality requirements, and client needs.
- Clean surface of rust, oil, dust; treat rusted areas with rust-conversion and anti-rust methods. Apply coating at ≥5°C.
- For smooth surfaces or equipment transporting special fluids/gases, plan additional interface layers if necessary.
- Apply Aerogel Radiative Cooling Coating to achieve required cooling effect or thickness. First layer ≤1mm, dry, then increase layers. From second layer, single layer ≤2mm. Final layer must be smooth. Natural drying 48h before use.
