文摘
- •
The addition of Altiris 800 greatly increases the NIR reflectance of the coating.
- •
The cool white roof coating can reduce the roof surface temperature by 30.8 °C.
- •
The low Tg of the binder endows the cool coating with moderate dirt resistance.
- •
Artificial accelerated weathering reduces the solar reflectance of the coating.
- •
The inferior weather resistance is due to the presence of C
C in the polymer chains.
