1.Ultra-Low Thermal Conductivity：Thermal conductivity as low as 0.018–0.030 W/(m·K) at ambient temperature, outperforming conventional insulation mortars and most organic insulation coatings.
2.High Efficiency in Thin Layers：Effective thermal insulation can be achieved with a dry film thickness of only 1–3 mm, ideal for space-limited applications and retrofit projects.
3.Excellent Fire Resistance：Based on inorganic silica, the coating can achieve A-class non-combustibility or near A-class fire performance (subject to test reports).
4.Wide Service Temperature Range：Stable performance from –50 °C up to 200 °C (higher ranges possible with specialized formulations).
5.Good Applicability：Suitable for spray, roller, or trowel application, adapting well to complex substrates and irregular surfaces.
6.Lightweight System：Low dry density minimizes additional structural load on buildings.
7.Energy Saving & Comfort Improvement：Reduces indoor heat gain in summer and heat loss in winter, improving indoor thermal stability and occupant comfort.
Aerogel coating Precautions & Application Guidelines
Substrate Preparation
● Substrate must be sound, clean, dry, and free of oil or loose particles
● Moisture content of concrete or mortar substrates should generally be ≤10%
● Metal substrates should be properly derusted, anticorrosion-treated, and primed
Application Conditions
● Ambient temperature: 5–35 °C
● Relative humidity: ≤85%
● Avoid application during rain, snow, or strong wind
Application Process
● Apply in multiple thin coats; avoid excessive thickness in a single pass
● Recommended interval between coats: 2–6 hours, depending on formulation and site conditions
● Allow sufficient curing time after reaching the design thickness (typically 24–72 hours)
Compatible System
● Use of a dedicated primer is recommended to enhance adhesion
● A protective topcoat is advised to improve weather resistance, durability, and stain resistance
Storage & Transportation
● Store in sealed containers, protected from direct sunlight and freezing
● Typical shelf life: 6–12 months

FAQ
1.Can aerogel coatings fully replace EPS, XPS, or mineral wool?
They can replace traditional materials in thin-layer insulation, equipment insulation, and retrofit applications, but are typically used as a high-performance complementary solution in ultra-low-energy buildings.
2.How can the actual energy-saving performance be evaluated?
● Performance can be assessed through:
● Infrared thermographic comparison
● Indoor/outdoor temperature monitoring
● Building energy simulations or third-party test reports
