Aerogel Insulation Paint

 

Key Properties：

1. Good high temperature stability: the thermal conductivity of aerogel materials changes little with the increase of temperature, and can still maintain excellent thermal insulation effect at high temperatures, while the thermal conductivity of traditional thermal insulation materials changes greatly when the temperature rises, resulting in decreased thermal insulation performance.

 

2. Light weight: aerogel itself is one of the lightest solid materials in the world, after being added to the paint, it will not increase the heavy load of the coated object, compared with traditional thermal insulation materials such as rock wool and other dense materials, the advantages are obvious, especially suitable for scenes with strict requirements on weight, such as aerospace, mobile equipment, etc.

 

3. Good flexibility and adhesion: It has excellent flexibility and adhesion, which can enhance the seismic performance of the surface of the coated object. The porous aerogel structure can also effectively absorb and disperse the energy caused by seismic waves, reducing the risk of damage to the object, while the traditional insulation materials such as glass wool and rock wool are brittle and have poor flexibility.

 

4. Strong durability: the nano three-dimensional network structure of aerogel provides excellent insulation stability, avoiding the phenomenon that traditional materials are easy to produce accumulation and deformation for a long time, and the insulation effect is sharply reduced, and its replacement cycle can reach about 20 years, which is longer than the service life of traditional insulation materials of about 5 years, and the use cost of the whole life cycle is lower.

1. Inhibit gas convection: aerogel has a nanoscale porous structure, and its porosity is extremely high, up to 80%-99.8%. These pores are extremely small, and the average pore size is usually smaller than the free path of air molecules (about 70nm at normal temperature and pressure). When the air is confined in such a small pore, the heat convection movement between molecules is greatly limited, and it is difficult to form an effective heat transfer channel, which inhibits the air convection heat transfer and makes it difficult to transfer heat through the air flow.

2. Reduce heat conduction: the solid skeleton of aerogel is made of nano-scale particles connected to each other, which makes the path of heat conduction in the solid skeleton become extremely tortuous and long. At the same time, the low thermal conductivity of the aerogel further reduces the conduction rate of heat in the solid material. As a result, the heat conduction through the solid skeleton is greatly reduced.

3. Blocking thermal radiation: the nanoporous structure inside the aerogel scatters and absorbs thermal radiation. When the heat radiation passes through the aerogel, it will constantly reflect and scatter between the pore wall and the solid skeleton, so that the propagation direction of the heat radiation is constantly changed, and the energy is gradually consumed. In addition, some components of the aerogel may have the ability to absorb specific wavelengths of thermal radiation, converting the radiant energy into other forms of energy, thus effectively blocking the transfer of thermal radiation.

When the aerogel is applied as a thermal insulation coating, these thermal insulation mechanisms work together to form an efficient thermal insulation barrier on the surface of the coated object, significantly reducing the heat transfer from the high temperature side to the low temperature side, and achieving a good thermal insulation effect.

1. What is the fire rating of the paint? Is there any relevant testing and certification? How long can the fire resistance limit be reached in the actual fire scenario?
The product fire rating can reach A level, with the testing certification issued by the authority. In the standard fire test, it can effectively delay the spread of the fire within a certain period of time, the specific fire resistance limit varies according to different test standards and coating thickness, under normal circumstances, the specific thickness of the coating can withstand 1-2 hours of high temperature flame impact.

2. How is the weather resistance of aerogel heat insulation coating? Long-term exposure to outdoor, such as ultraviolet, rain, high and low temperature alternating environment, how long will the performance decay?
The coating has excellent weather resistance, and the special formula and process make it effectively resist ultraviolet and rain erosion. After simulated accelerated aging test, under normal outdoor use conditions, it is expected that a slight performance attenuation will occur in 10-15 years, and the overall insulation effect will not be affected. The actual service life may vary depending on the specific environment.

3. How is the waterproof performance of the product? Can it prevent water vapor from penetrating and protect the inside of the coated object from moisture?
The aerogel thermal insulation coating has good waterproof performance, and the hydrophobic rate can reach more than 98%. It can effectively block water vapor penetration and provide reliable moisture protection for coated objects in humid environments.

4. What is the price of aerogel insulation paint? What are the cost advantages over traditional insulation materials?
Product prices will vary depending on the specific model and quantity purchased. Although the initial purchase price may be higher than some traditional thermal insulation materials, in the long run, due to its good thermal insulation performance, it can significantly reduce energy consumption, reduce equipment maintenance and replacement frequency, and the overall cost is lower. For example, in building insulation, energy consumption costs can be reduced by 30%-50%.

5. What scenes and material surfaces is this paint suitable for? How is the adhesion to different materials?
Widely used in building exterior walls, roofs, industrial pipes, equipment tanks, electronic appliances and other fields. It has good adhesion to metal, ceramic, glass, concrete, plastic and other material surfaces. Proper cleaning and pretreatment of the surface before construction can further enhance the adhesion.

6. Is the construction process complicated? Do you need a professional construction team? What are the precautions in the construction process?
The construction process is relatively simple, and can be applied by spraying, brush coating, roll coating, etc. Although it is not mandatory to have a professional construction team, the construction effect is better with personnel who have undergone simple training. During construction, it should be noted that the ambient temperature should be between 5 ° C and 40 ° C, the air humidity should not be higher than 85%, and the coated surface should be clean, dry and free of oil.

7.Could you provide us with samples for testing? What is your response time if technical support is required?
Appropriate samples can be provided for your testing. If you need technical support, we have a professional technical team, after receiving the demand, within 24 hours to give a response, and according to the actual situation as soon as possible to arrange technical personnel to arrive at the scene.
