CNT-reinforced fire-resistant coatings improve thermal insulation and fire retardancy in buildings, vehicles, and industrial facilities.

✔ Benefits:

• Reduced fire spread and improved safety.
• Enhanced thermal stability in aviation and space applications.
• Improved protection of critical infrastructure in high-temperature environments.

3. Dual-Climate Applications: Adaptability to Both Cold and Hot Conditions

✔ CNT-Based Smart Roads:
