Product Description

 **HW-222 Special Sealant for Power Energy Storage System**

**Product Features**
HW-222 is a high-performance, multifunctional sealant designed for power energy storage devices, providing excellent thermal conductivity, flame retardancy, weather resistance, insulation and waterproof performance,
fully meeting the stringent requirements of energy storage systems.

**Key Applications and Advantages**
1. **Thermal Conductivity and Flow Performance**
- Efficient thermal conductivity: With excellent thermal conductivity, it ensures rapid heat transfer between battery packs and improves the overall system heat dissipation efficiency.
- Strong flow performance: It is easy to fill the gaps between complex components, ensuring close contact and efficient heat conduction between battery packs.

2. **HVAC system sealing**
- Internal and external barriers: The sealant has efficient sealing performance, effectively isolates air exchange and avoids leakage.
- Improve energy efficiency: Supports the optimized operation of the HVAC system and improves the overall energy efficiency of the energy storage compartment.

3. **Flame retardant function**
- High flame retardant grade: When irreversible thermal runaway occurs inside the battery pack, the sealant can effectively suppress the spread of open flames and ensure system safety.
- Comply with international flame retardant standards and provide an additional protective barrier for the energy storage system.

4. **Weather-resistant caulking**
- Excellent weather resistance: It can be used to seal the air vents inside and outside the energy storage compartment, with a service life of more than 30 years, UV resistance, high and low temperature resistance.
- Long-lasting stability: It can maintain sealing and functional integrity even under extreme climatic conditions.

5. **Insulation and waterproofing**
- Strong insulation: It forms reliable electrical insulation protection at the wiring harness joint to avoid arc and short circuit risks.
- Excellent waterproof performance: Prevent moisture intrusion to ensure that the energy storage system can still operate stably in a high humidity environment.

**Packaging specifications and colors**
- Packaging: 300ml ink cartridge, 600ml sausage, 20L barrel (customizable)
- Color: gray [other colors can be customized]

**Storage and usage instructions**
- **Storage conditions**: Store in a dry and ventilated environment, temperature ≤25ºC, avoid direct sunlight.
- **Shelf life**: 12 months from the date of production.
 

We use raw materials supplied by the world's leading chemical giants,
Chemical material inventory of thousands of tons or more.Have more production capacity than peers.
 The adhesive manufacturing process is completely enclosed to prevent external temperatures and various uncontrollable factors from affecting the product quality.

APPLICATION
Apply to clean, dry and grease-free surfaces. Cut the nozzle at 45°angle to the desired shape and size. For better appearance, cover outside of joint areas with masking tape before application.  
 Tool immediately after sealant application and remove masking tape before sealant skins.

Caution
Uncured silicone can irritate eyes and skin. If contact is made with eyes, flush with water for 15 minutes and seek medical advice. Use in well ventilated area and keep out of reach for children.
LIMITATIONS
1.Unsuitable for curtain wall structural applicatio
2.Do not use for below ground.
3.Do not use when substrate temperature is above 50ºC or surfaces that are wet, oily, greasy, dusty or dirty.
4.The surfaces coated with paint are unsuitable for sealant.
5.Do not clean or treat the sealant with materials, solvents or cleaning agents that may affect or discolor the sealant, particularly during sealant cure.
