AG-C Aerogel High Temperarure thermal Insulation Coating are formulated by blending nanoporous SiO₂ aerogel powder with an inorganic binder into a viscous water-based paste, and can be conveniently applied via troweling, scraping, or spraying. AG-C200, AG-C400, and AG-C600 are designed for operating temperatures up to 250℃, 450℃, and 650℃, respectively.Boasting long service life, Class A fire resistance, and superior thermal insulation, these coatings are ideal for insulating industrial high temperature pipes, equipment, valves, flanges, and other irregular parts. They also function as caulking or bonding agents in high-temperature environments and prevent pipe scalds, effectively resolving the "last mile" problem of thermal insulation.
As a professional China aerogel manufacturer with full in-house production capacity from nano aerogel powder to finished coatings, we develop and produce AG-C HT Series High Temperature Aerogel Coating. This series is a water-based industrial thermal insulation solution, with our proprietary nano porous silica aerogel powder as the core functional raw material.
It is specially designed for the harsh working conditions of industrial high temperature scenarios range from 250°C to 650 °C. It completely solves the core pain points of traditional rock wool, ceramic fiber and calcium silicate materials, which have been unable to be solved for a long time. It is widely recognized by global petrochemical, thermal power and smelting industry clients.
The industry-leading performance of AG-C HT Aerogel Coating comes from the nano porous structure of its core aerogel powder raw material. The three-dimensional nano network structure of silica aerogel powder locks static air inside the coating, and effectively suppresses heat conduction, convection and radiation at the same time.
This unique structure allows the coating to maintain stable thermal insulation performance under long-term high temperature working conditions. It will not appear powdering, performance degradation or structural damage, which are common problems of traditional high temperature insulation materials.
Traditional high temperature insulation materials must be installed after the equipment is shut down and cooled down. For petrochemical pipelines, smelting equipment and thermal power generation systems, even a short shutdown will bring hundreds of thousands of economic losses.
AG-C HT Aerogel Coating can be directly applied on the surface of running high temperature equipment. It quickly forms a dense and stable protective layer during construction, with excellent thermal shock resistance. This feature completely eliminates the need for production shutdown, and saves huge direct and indirect economic losses for your plant.
Valves, flanges, elbows, pump bodies and other irregular parts are always the weakest points of industrial thermal insulation systems. Traditional sheet and blanket materials can not fully fit the complex curved surfaces. They are difficult to cut and install, and will leave a large number of gaps.
These gaps will cause serious heat loss, local overheating and even safety accidents. Our paste coating can perfectly adapt to any irregular surface and narrow installation space. It achieves seamless and dead-angle-free full coverage insulation, completely solving the last mile problem of industrial thermal insulation.
Traditional high temperature insulation coatings are easy to crack, hollow and peel off during thick layer construction. They require multiple times of thin coating, and long waiting time for drying between each pass. This leads to long construction period and high rework rate.
AG-C HT Aerogel Coating has excellent structural stability. It will not crack or hollow during thick layer construction, and can achieve high flatness after one-time molding. It has a bonding strength of more than 0.6MPa with the substrate, and will not peel off under long-term thermal shock cycles. This greatly shortens the construction period, and reduces repeated rework and maintenance costs.

Poor thermal insulation performance of traditional materials leads to continuous heat loss of high temperature pipelines and equipment. This pushes up the temperature control energy consumption of the production line, and brings rising energy bills month after month.
The nano aerogel core of AG-C HT Aerogel Coating delivers excellent thermal insulation performance. It greatly reduces the heat loss of high temperature equipment, and cuts the overall energy consumption of the production line by a large margin. The stable performance can last for more than 10 years, bringing continuous energy saving benefits for your project.
Industrial high temperature scenarios have extremely strict requirements for fire safety and on-site operation safety.
Flammable traditional insulation materials bring huge fire hazards, and exposed high temperature surfaces are the main cause of scald accidents in the plant.
AG-C HT Aerogel Coating meets the highest industrial flame retardant standards. It will not burn or release harmful substances under high temperature environment. The tight bonding layer also forms a reliable anti-scald protective barrier on the equipment surface, effectively reducing the safety risk of on-site operators, and fully complying with the global industrial safety management specifications.
AG-C HT Aerogel Coating uses 100% water-based formula, with no volatile harmful organic compounds. The whole process of production, construction and use is safe and environmentally friendly, and will not produce harmful residues.
It has wide compatibility with other industrial coating systems. You can choose matching high temperature primer to enhance adhesion and anti-corrosion performance, or apply protective topcoat on the surface according to the anti-corrosion and decorative needs of the project.

Aerogel high-temperature coating is a thin, flexible insulation material applied directly to equipment surfaces. It provides surface temperature reduction for personnel protection and insulation of complex or irregular equipment geometries.
AG-C Aerogel high-temperature coatings can be applied directly to irregular or complex surfaces such as valves, elbows, and flanges, providing effective anti-burn protection in thin layers. Their hydrophobic properties reduce moisture absorption and lower the risk of corrosion under insulation (CUI), while the lightweight formulation adds minimal load to equipment. Additionally, the coatings are flexible, allowing for localized application and easy maintenance.
AG-C Aerogel high-temperature coatings are used to insulate industrial equipment operating at high temperatures, while also providing personnel protection from burns. They are ideal for surfaces that are difficult to cover with traditional insulation, such as valves, flanges, elbows, and rotating machinery components. For example, the hot surfaces of a coal mill can be coated to prevent burn hazards and reduce surface heat loss in areas where blankets or rigid insulation cannot fit.
