Aerogel Fire-Proof Coating (AG-FPC)

AG-FPC is a water-based fireproof and thermal insulation coating formulated with silica aerogel powder and other inorganic components. It appears as a light yellow transparent liquid with 50–60% solid content and zero VOC. When exposed to flame or high temperature, it expands rapidly — five to twenty times — forming a dense insulating char layer that blocks heat transfer and delays flame spread. It is non-conductive, which suits applications requiring electrical safety. Typical uses include new energy vehicles, mobile phone batteries, electronics and electrical appliances, fire doors and fire-resistant glass, as well as building fire protection and industrial equipment insulation.

The AG-FPC series covers six grades matched to different operating temperature requirements: AG-FPC-10 for 1000°C, AG-FPC-11 for 1100°C, AG-FPC-12 for 1200°C, AG-FPC-13 for 1300°C, AG-FPC-14 for 1400°C and AG-FPC-15 for 1500°C. This allows specifiers to select precisely against the thermal exposure of the application rather than over- or under-specifying. The general working temperature range is stated as 20°C to 1500°C depending on grade. Grade selection should be based on the maximum credible exposure temperature and required protection duration; the technical team can assist with selection when provided with the application details and substrate.

Published properties include adhesion above 0.5 MPa by pull-off method, specific gravity of 1.3–1.4 kg/L, viscosity of 500–2000 cPs, expansion ratio of 5–20 times, solid content of 50–60%, drying time of at least 24 hours at room temperature, and zero VOC. Thermal shock resistance and temperature-humidity cycling comply with GB/T 31467.3-2015, a standard associated with battery pack safety requirements, and prohibited substances comply with REACH/RoHS testing. Buyers should note that fire-performance claims for a specific assembly, such as a fire door rating, depend on the tested system, so project-level certification should be confirmed case by case.

AG-FPC requires no primer and can be applied directly by spraying, brushing or rolling onto metal, concrete, plastic and wood substrates, with reported excellent adhesion and long-lasting weather resistance. Substrates should be clean, dry and free of oil, dust, rust and loose material to achieve the published pull-off adhesion. Because it is an intumescent system, uniform film build is critical to achieving the designed expansion layer; applicators should control wet film thickness consistently and respect the 24-hour minimum drying time at room temperature before handling or topcoating. Recommended dry film thickness per application is not published on the page; confirm in the current TDS.

AG-FPC is a pure inorganic intumescent coating, non-toxic and water-based, but buyers should understand its boundaries: fire protection performance depends on applied film thickness, substrate, and the complete assembly, and the coating alone does not constitute a certified fire-rated system; drying requires at least 24 hours at room temperature, longer in cold or humid conditions; and grade selection must match real exposure temperature. Packaging format, shelf life and minimum order quantity are not published on the page; confirm these in the current TDS or with the sales team. Samples can be arranged for adhesion and expansion checks on your actual substrate before project ordering.
