Product Detail

How AG-CJZ Aerogel Coating Delivers Superior Heat Blocking Performance


The industry-leading heat insulation performance of AG-C aerogel coating comes from the unique nanoporous structure of its core aerogel powder raw material. 


The nano-scale silica aerogel particles in the coating form a 3D network structure with 20-50nm ultra-fine pores, which is 1/5000 of the diameter of a human hair. This innovative nano structure can:


Locks static air in the nanopores, completely suppressing gas convection and solid heat conduction;

Delivers ultra-high mid-far infrared emissivity, blocking thermal radiation transfer;

Works with the reflective topcoat to reflect more than 85% of solar radiation heat, stopping heat from entering the interior from the source;

Core Advantages of AG-CJZ Aerogel Thermal Insulation Coating


AG-CJZ aerogel coating redefines the performance limit of thin-layer thermal insulation materials. With the unique nanoporous structure of its aerogel powder raw material, 2mm thick coating delivers equivalent thermal resistance of 40mm traditional rock wool, achieving 20 times higher heat insulation efficiency per unit thickness.


With an ultra-low thermal conductivity of ≤0.035-0.044 W/(m·K) at 25℃, it creates a 4-6℃ indoor temperature difference in buildings compared to uncoated surfaces under summer high-temperature conditions, it drastically reduces air conditioning running time and load, cutting cooling energy consumption by up to 40% for long-term use maintains stable heat blocking performance in the temperature range of -40℃ to 120℃, suitable for extreme weather conditions across the globe.

Technical Parameters


Superior Hydrophobicity for Long-Lasting Moisture & Mildew Resistance


AG-CJZ Aerogel Coating features permanent hydrophobic modification on the core aerogel powder particles, delivering excellent water repellency while maintaining breathability of the wall.


The coating surface forms a lotus leaf effect, with no water hanging or penetration, effectively preventing wall seepage and damp return, which eliminates the humid environment required for mold growth from the root, achieving long-lasting mildew and algae resistance, extending the service life of the building wall by more than 3 times.


It also has Excellent stain resistance and self-cleaning effect, the coating surface remains clean and intact for a long time even in harsh outdoor environment.



Lightweight, Crack-Resistant & Zero Detachment Risk


Unlike thick traditional insulation boards that have heavy load, easy cracking and high falling risk, AG-CJZ aerogel coating solves these industry pain points once and for all:


Ultra-lightweight design: dry film weight is only ~300g/m², reducing the load on the wall by 2-10kg/m² compared to traditional rock wool boards


Super strong adhesion: bonding strength up to ≥0.6MPa, tightly integrated with the substrate, no hollowing, no falling off


Excellent crack resistance: flexible coating formula adapts to the thermal expansion and contraction of the wall, no cracking, no peeling under long-term temperature changes


Streamlined Construction, Cost & Time Saving


aerogel thermal barrier coating system completely subverts the complex construction process of traditional insulation materials:

Traditional external wall insulation requires 9-13 construction procedures, while our coating system only needs 3 procedures (primer + middle coating + topcoat)

It can be applied by spraying or scraping, directly on the existing wall substrate without removing the original finish, drilling or installing fixtures, which will cuts overall project construction time by more than 50%, reduces total project cost by 10-15%, and has no impact on residents' daily life during the renovation of existing buildings


Water-Based, Eco-Friendly & Safe Formula


AG-CJZ Aerogel Coating uses a 100% water-based, solvent-free formula, which is non-toxic, harmless and fully compliant with global environmental protection standards:


No volatile organic compounds (VOCs), no harmful substances residue during production and construction

Lower carbon footprint than traditional rock wool insulation boards, reducing carbon emissions by 3,076.25 kg per ton of product

Fully meets the low-carbon and energy-saving requirements of green building certification around the world


 Application Scenarios

Building & Construction Sector

External wall, roof, curtain wall thermal insulation and energy-saving renovation of commercial buildings, residential buildings, public facilities;

Thermal insulation and mildew prevention for sunrooms, swimming pool enclosures, prefabricated buildings and historic building renovation;

Thermal insulation and heat protection for interior walls, ceilings;

Moisture-proof and mildew-proof in underground or hospitals;

Product FAQ

If you have any questions about the product, please feel free to contact our technical experts at any time via E-mail: lexie@ag-tech.cn

  • 01

    How does AG-C Aerogel Midcoat compare to rock wool and insulation mortar?

    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. 

  • 02

    Is applying aerogel midcoat difficult?

    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.

  • 03

    Is aerogel coating safe for human health?

    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.


  • 04

    Why does AG-C Aerogel Insulation Midcoat maintain adhesion better than conventional coatings?

    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.


  • 05

    Must the primer and topcoat for the Aerogel midcoat be AG Brand?

    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.

  • 06

    What application scenarios is AG-C Aerogel Insulation Midcoat suitable for?

    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
