Silica Aerogel Paint

Why Choose Silica Aerogel Paint?

1. Ultimate Thermal Insulation, Significantly Reduced Energy Consumption

As a derivative of silica aerogel, the "king of thermal insulation materials," Silica Aerogel Paint boasts a thermal conductivity as low as ≤0.020 W/(m・K), significantly superior to traditional thermal insulation coatings (e.g., polyurethane coatings, approximately 0.030 W/(m・K) and rock wool coatings, approximately 0.045 W/(m・K)).

Architectural Applications: Applying it to exterior walls, roofs, or interior walls can reduce outdoor heat infiltration in summer (reducing air conditioning load by 30%-50%) and prevent indoor heat loss in winter (reducing heating energy consumption by 25%-40%).

Industrial Applications: Applying it to pipes, storage tanks, and boiler surfaces effectively insulates media from high temperatures (e.g., steam pipes) or low temperatures (e.g., refrigerated storage tanks), reducing heat loss and helping businesses achieve energy savings.

2. High-temperature and weather-resistant, suitable for complex environments

Silica Aerogel Paint offers a wide temperature resistance range (-60°C to 600°C, with some industrial-grade models reaching 1200°C) and is resistant to UV rays, aging, and acid and alkali corrosion.
High-temperature applications: Coating the exterior walls of industrial kilns, automotive exhaust pipes, and new energy battery pack casings resists high-temperature oxidation, protects the substrate, and reduces ambient temperature.
Outdoor applications: Building exterior walls exposed to rain, snow, and intense sunlight for extended periods of time offer a coating that resists cracking and peeling, with a service life of up to 15-20 years (compared to the approximately 8-12 years for traditional thermal insulation coatings).

3. Ultra-light and thin, no additional burden on the substrate

Compared to traditional insulation materials (such as insulation wool and insulation board), Silica Aerogel Paint has a cured coating thickness of only 0.5-2mm and weighs ≤1.5kg per square meter, adding virtually no additional load to the substrate.

It is suitable for weight-sensitive applications such as historic building restoration, lightweight steel structures, and glass curtain walls, without the need for additional substrate reinforcement.

Coating retains the original dimensions of pipes and equipment, eliminating installation space constraints caused by excessively thick insulation.

4. Environmentally friendly and non-toxic, meeting green standards

Using a water-based emulsion as a carrier, it contains no formaldehyde and has a VOC (volatile organic compound) level of ≤10g/L, far below the EU EN 15102 environmental standard (VOC ≤150g/L).

It is odorless when used indoors in buildings and poses no health risks.

In industrial applications, it emits no toxic substances, meeting corporate environmental emission requirements and contributing to the achievement of the "dual carbon" goals. 5. Easy Application, Compatible with Various Substrates
Silica Aerogel Paint can be applied using standard paint application methods, such as brush, roller, and spray, eliminating the need for specialized heavy equipment. It adheres tightly to a variety of substrates, including metal (steel, aluminum alloy), concrete, masonry, glass, and wood. Its fast drying speed (touch-drying in ≤ 2 hours, through-drying in ≤ 24 hours at 25°C) shortens application time and reduces labor costs.

 

Key Properties：

1. Low density: It is one of the lightest solid materials in the world, only three times as heavy as air, and will not add too much weight to the coated object.

 

2. High porosity: the porosity is usually 80.0% to 99.8%, and a large number of pores make the coating have a certain air permeability, which helps to reduce water vapor condensation.

 

3. Strong thermal insulation performance: low thermal conductivity makes it able to effectively block the transfer of heat, which can significantly reduce the heat loss or absorption of buildings, equipment, etc., play a good role in thermal insulation and help save energy.

1. Building Energy Efficiency

Insulation of exterior walls, roofs, and interior walls of new/renovated buildings;

Energy-saving renovations for passive buildings and green buildings (helping achieve green building certification standards such as LEED and BREEAM);

Insulation of interior walls of cold storage and temperature-controlled warehouses (reducing cooling loss).

2. Industrial Thermal Insulation

Insulation of exterior walls of steam pipes, high-temperature storage tanks, and reactors in the power and petrochemical industries;

Insulation of furnace bodies and flues in the metallurgical and kiln industries (reducing ambient temperature and protecting operators);

Protection of high-temperature components in exhaust pipes and engine compartments of automobiles and ships.

3. New Energy and Electronics

Insulation of photovoltaic backsheets in photovoltaic power plants (reducing backsheet temperature and increasing photovoltaic module efficiency by 5%-8%);

Thermal management coatings for power battery packs (suppressing the spread of thermal runaway and improving safety);

Thermal insulation of electronic device casings (preventing high temperatures from affecting device stability).

Does Silica Aerogel Paint require other insulation materials for its thermal insulation benefits?

In most cases, no. A 1-2mm thick coating on building exteriors or industrial pipes is sufficient. For extreme insulation (such as ultra-low temperature storage tanks), it can be combined with a thin layer of insulation to further reduce heat loss.

Is a topcoat required for outdoor use?

No topcoat is required. The paint itself is UV-resistant, rain- and snow-resistant. After curing, it forms a dense protective film that will not fade or crack with long-term outdoor use.

How long after application can it be used?

At 25°C, it can be used after 24 hours of full drying. At lower temperatures (<15°C), the coating can be extended to 48 hours to ensure complete curing.

Can it be applied directly onto rusted metal pipes?​
It's recommended to first prepare the surface-remove rust and oil stains from the metal surface, then apply an anti-rust primer (such as epoxy). Once the primer is completely dry, apply Silica Aerogel Paint to improve adhesion and overall protection.

Silica Aerogel Paint not only provides efficient insulation and energy savings, but also adapts to diverse and complex environmental requirements. It's the preferred coating solution for cost reduction and efficiency improvement in the construction, industrial, and new energy sectors.
