Principle

• Earthcoat thermal insulation coating is a new-generation composed of water-based resin, Earthcoat particles, microspheres.
• The hollow microspheres in EC-I Earthcoat insulation mid-coat contain a near vacuum internal structure.
• Earthcoat particles feature up to 95% porosity with pore sizes below 50 nm (smaller than the mean free path of molecules).
• This structure makes heat transfer within the coating extremely difficult.

Advantages

• The coating interface reflects heat and creates extremely high interfacial thermal resistance.
• A 2–3 mm coating thickness delivers thermal insulation performance equivalent to more than 10 times that of conventional insulation materials.

Working Mechanism

Low Thermal Conductivity + Heat Reflection

• Heat transfer QQ from the high-temperature side to the low-temperature side consists of:
  • Q₁: Conductive Heat Transfer
  • Q₂: Radiative Heat Transfer
• Due to the high emissivity of the filler, Q₂ contributes significantly more than in conventional materials.
• The internal hollow spherical structure and Earthcoat porous structure:
  • Refract and reflect thermal radiation, reducing radiative heat transfer efficiency.
  • As a result, Q₂ transfer efficiency is extremely low, giving the coating high thermal resistance.
