AG-C Aerogel Insulation Midcoat

AG-C Aerogel Middle Coating is designed to block heat transfer and condensation via thermal reflection, radiation, and conduction. the thermal conductivity is ultra-low, ideal for energy-saving retrofits on building exteriors, roofs and scenarios that require anti-condensation measures. The core component of the coating is AG-S aerogel slurry. This advanced thermal insulation Coating is formulated with water as a solvent and contains more than 35% aerogel by volume. We can provide you with conprehensive technical support and raw material to produce aerogel coating independently.

Product Detail

Applied as the intermediate aerogel layer in an aerogel coating system (primer + aerogel midcoat + topcoat), it forms a dense and durable insulating barrier on the substrate surface. This barrier works through three synergistic mechanisms, reflection, radiation, and conduction blocking to effectively reduce heat transfer between indoor and outdoor environments.


Main advantages:

Superior insulation performance: Reduces solar radiation heat gain and minimizes cooling costs.

Durable protection: Extends the lifespan of building and industrial assets by resisting moisture and mold growth.

High cost-effectiveness: Offers an excellent balance of performance and application cost, featuring easy construction with fewer processes. A 2mm aerogel layer can lower indoor temperatures by 5-6℃, delivering outstanding long-term energy savings.

Energy-efficient & eco-friendly: Water-based formula, fully compliant with green building standards.


Application Scenarios:

Energy-saving renovation of old residential buildings or warehouse

Thermal insulation and for exterior walls of new energy-efficient buildings

External insulation and anti-condensation for server rooms and cabinets

Moisture and mold prevention for strict hygiene environments like hospital and basement.

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
