AG-C Aerogel Thermal Insulation Middle Coating is developed to reduce heat transfer and condensation by limiting heat conduction, radiation, and reflection. With ultra-low thermal conductivity, it is suitable for energy-saving retrofits on building façades, roofs, and other applications where anti-condensation performance is required. This water-based aerogel coating contains over 35% aerogel by volume. We provide comprehensive technical support and aerogel materials to enable independent production of aerogel coatings for coating manufacturers.

Aerogel coating applied as the intermediate aerogel layer in an aerogel coating system: primer, aerogel middle coating, topcoat. Construction is convenient, and the procedures are simpler compared to traditional materials.
Aerogel Coating Advantages
Remarkable Economic Benefits
Thanks to the streamlined application process of aerogel coatings, this solution reduces overall project costs by 10–15% and cuts construction time by more than 50%
Superior Thermal Insulation Performance
With outstanding thermal resistance, buildings using aerogel coatings experience a 4–6°C difference in perceived temperature compared to buildings without aerogel coatings. Long-term use dramatically lowers air conditioning energy consumption and reduces electricity costs.
Lightweight, Crack-Resistant, and Detachment-Free
The aerogel coating achieves a substrate bonding strength of over 0.6 MPa and a dry weight of only ~300g/m².At just 2mm thick, it reduces weight by 2–10 kg/m² compared to traditional rock wool boards, minimizing detachment risks while delivering exceptional adhesion, durability, and crack resistance.
Simple Construction, Resident-Friendly
Aerogel thermal insulation coatings can be applied directly to the existing substrate of exterior walls, eliminating the need to remove original finishes, drill, or install fixtures. This hassle-free process cuts construction costs and ensures work proceeds without disrupting residents’ daily lives.
Excellent Hydrophobicity
The coating exhibits strong water repellency, stain resistance, and a self-cleaning effect that keeps surfaces looking pristine over time.
Safe, Eco-Friendly, and Low-Carbon
Formulated with a water-based, solvent-free formula, the aerogel coating is non-toxic, harmless, and meets stringent environmental standards. Its carbon footprint is lower than that of rock wool boards, reducing carbon emissions by 3,076.25 kg per ton.

AG-C aerogel middle coating's thermal conductivity ≤0.044W/(m·K), only 2mm thickness AG-C aerogel middle coating equals 20mm rock wool or 42mm insulation mortar.
Not at all. AG-C Aerogel midcoat is easy to apply, typically requiring only 3–4 simple steps. It can be directly sprayed onto surfaces, and compared with traditional materials, it can significantly reduce construction time and costs.
Yes. Aerogel coatings are water-based and low in VOCs, making them environmentally friendly and safe for construction use.
AG-C Aerogel Midcoat is primarily used for exterior insulation, with low VOC content.
AG AeroSpace is designed for interior walls, offering high safety and minimal formaldehyde, making it suitable for indoor applications.
Conventional coatings may delaminate due to factors like moisture in the substrate, thermal expansion, or thick layering.
AG-C Aerogel Insulation Midcoat, being ultra-light (≈300 g/㎡) and thin (2–3 mm), forms a continuous, crack-resistant layer. Its nanoporous aerogel structure reduces stress from expansion and contraction, helping the coating maintain adhesion under normal conditions, without relying on excessive thickness.
No. Customers can use AG Brand primers and topcoats, or suitable locally available water-based primers and topcoats to match the aerogel midcoat. Proper substrate preparation and compatibility with the midcoat should be ensured.
AG-C Aerogel Insulation Midcoat is suitable for a variety of applications, including:
Renovation of older residential buildings
Energy-efficient exterior wall insulation projects
Areas prone to condensation or mold, but with high hygiene requirements, such as basements or hospitals
