I. Thermal Insulation Mechanism
The insulation mechanism of aerogel coatings is primarily reflected in three aspects: blocking thermal conduction, heat reflection, and radiative thermal insulation/heat retention.
II. Application Scenarios
Mainly used for exterior walls in regions with "Hot Summers and Cold Winters" or "Hot Summers and Warm Winters."
Building Types: High-end residential complexes, Grade-A office buildings, wellness and healthcare facilities, cultural and tourism venues, and landmark architectural facades.
Substrate Compatibility: Fully compatible with concrete, real stone paint, insulation boards, steel structures, and curtain wall systems.
III. Core Values
4-in-1 Multifunctionality: Integrates thermal insulation, hydrophobicity (water repellency) & weather resistance, crack & mold resistance, and eco-friendly energy saving.
Ultra-Thin & Lightweight: A thin coating of 2–5mm adds negligible weight and does not alter the aesthetic texture of the facade.
Summer Performance: Reduces indoor temperatures by 3–8°C, achieving 25%–35% energy savings on air conditioning.
Winter Performance: "Locks" in temperature to reduce heat loss, achieving 20%–30% energy savings on heating.
Superior Durability: Resistant to acid rain, salt spray, and intense sun exposure. Its high elasticity resists cracking caused by thermal expansion and contraction.
Sustainable Living: Extends the exterior wall renovation cycle to 8–10 years. The water-based formula meets green building standards with zero odor, ensuring a human-friendly environment.
IV. Technical Specifications (Core Indicators)
Temperature Resistance: -40°C to 120°C
Thermal Conductivity: ≤ 0.044 W/(m·K)
Adhesion Strength: ≥ 0.6 MPa
Environmental Standard: Water-based, eco-friendly, and zero formaldehyde.
V. Application Procedure (Construction Process)
The application follows this sequence: Substrate Treatment → Putty Application → Primer → Aerogel Insulation Mid-coat → Topcoat.
Drying Time: Each subsequent layer must be applied only after the previous layer is completely surface-dry.
Uniformity: All materials must be applied evenly and achieve a firm bond between layers.
Substrate Treatment Requirements:
The wall surface must be clean and free of debris.
Moisture Content: If moisture is >10%, let it dry. If ≤8%, lightly moisten with water, wait for surface water to disappear, then apply an interface agent.
pH Value: If pH >10, apply alkali-resistant putty for sealing.
Putty Application:
Applied in 2–3 layers; each layer should not exceed 2mm in thickness.
Sand each layer after drying to remove dust; the final layer must be sanded perfectly flat.
The primer can be applied via roller, brush, or spray, working from top to bottom.
Aerogel Mid-coat Application:
Recommended for troweling or spraying at temperatures between 5°C and 40°C.
Troweling: Apply in stages; each layer should not exceed 2mm. Ensure each layer is compacted and firmly bonded.
Spraying: Can be applied in a single pass to reach the specified thickness.
Final Step: Allow the aerogel mid-coat to dry thoroughly (72 hours at room temperature) before applying the decorative topcoat.
VI. Engineering & Economic Benefits
Cost Efficiency: Reduces comprehensive construction costs and eliminates frequent post-maintenance expenses.
Energy Savings: Continuously lowers building energy consumption, providing long-term cost reductions for both property management and owners.
Problem Solver: Solves common industry pain points where exterior insulation fails to be waterproof, or waterproof layers fail to resist temperature fluctuations and cracking.
Asset Value: Enhances building quality and competitiveness with a coating lifespan of ≥8 years, providing long-term peace of mind.
✅ Precautions
Weather Conditions: Suspend construction during extreme temperatures, high humidity, rain, snow, or strong winds.
Protection: Avoid scratching the finished surface with sharp objects.
Easy Repair: Localized damage can be repaired by re-coating with the same model, resulting in a seamless finish with no color difference.
Compatibility: Highly compatible with all mainstream exterior wall substrates, ensuring high construction efficiency.
