| Performance Comparison | Aerogel Coating | Traditional Thermal Insulation Materials |
|---|---|---|
| Thermal Insulation Effect & Heat Preservation Performance | Thermal conductivity ≤ 0.15W/(M·K); 3D network pore structure, providing superior heat preservation effect | Polystyrene board: approx. 0.035W/(M·K); Rock wool board: 0.035 - 0.047W/(M·K) |
| Fire Resistance Rating | Generally Grade A or A2, low risk, classified as Grade A fire-retardant material | Polystyrene board, polyurethane foam, etc. usually have low fire resistance rating; Rock wool board is Grade A, but some unqualified products have risks |
| Construction Convenience | Can be applied by spraying, brushing, scraping and other methods; simple construction, low skill requirements for construction workers, adaptable to different substrate structures and surface morphologies | Requires cutting, splicing, fixing and other processes during construction, which is relatively complicated, and has certain requirements for the skills of construction workers |
| Lightness & Thinness | Thickness only needs about 1-2mm, saving space and reducing building load | Thickness usually needs 30-50mm, or even thicker |
| Waterproof & Moisture-proof | Water repellency rate can reach 99% and above, not easy to absorb water and get damp | Some insulation boards need waterproof treatment, and their thermal insulation performance will decrease after water absorption |
| Service Life | Can reach more than 10-15 years, even up to 30 years according to some data | Affected by factors such as base wall treatment and adhesive quality, problems such as falling off may occur after several years of use, affecting the service life |
Application Steps for Aerogel Thermal Insulation Coating
1. Surface Preparation
Clean the wall or roof surface thoroughly before application. Remove dust, grease, loose particles, old peeling paint, and moisture to ensure proper coating adhesion.
2. Surface Repair and Priming
Repair cracks, holes, or uneven areas if necessary. Apply a suitable primer based on the substrate type to improve bonding performance and coating durability.
3. Coating Mixing
Stir the aerogel insulation coating evenly before use. Follow the recommended mixing instructions to maintain stable coating consistency and insulation performance.
4. Coating Application
Apply the coating evenly by spray, roller, or brush according to project requirements. Multiple thin layers are generally recommended instead of one excessively thick layer.
5. Drying and Curing
Allow sufficient drying and curing time between layers and after final application. Drying conditions should follow the product technical guidelines for optimal performance.
6. Final Inspection
Check coating thickness, surface uniformity, and adhesion after curing to ensure the insulation layer meets project standards.
Important Application Considerations
Ensure Proper Surface Dryness
Do not apply the coating on wet or heavily damp surfaces, as moisture can affect adhesion and coating stability.
Avoid Extreme Weather Conditions
Outdoor application should avoid rain, snow, strong wind, or extremely high humidity conditions during construction and curing.
Control Coating Thickness
Excessively thick single-layer application may affect drying efficiency and surface quality. Follow the recommended coating thickness guidelines.
Use Compatible Primers and Topcoats
Select primers and finishing coatings that are compatible with aerogel insulation materials to maintain long-term performance.
Follow Recommended Temperature Range
Application should be carried out within the recommended ambient temperature range to ensure proper curing and insulation effectiveness.
FAQ
1. Does the coating crack or peel under high temperatures?
Properly applied industrial-grade coatings are formulated for thermal stability and adhesion under demanding operating conditions.
2. What application methods are available?
The coating can typically be spray-applied or manually applied depending on project size and surface requirements.
3. Can customized fireproof solutions be provided?
Yes. Coating thickness, formulation, and performance targets can be adjusted according to project needs and industry standards.
4. Is the coating environmentally friendly?
Many aerogel-based coatings are designed with low material consumption and energy-saving benefits, supporting more sustainable industrial operations.
5. How can buyers choose the correct coating specification?
Selection depends on operating temperature, fire protection requirements, substrate type, and environmental conditions. Our technical team can recommend a suitable coating system based on your project details.
