How PERFECT COOL works

PERFECT COOL is the pavement which can reduce thesurface temperature by applying PERFECT COOL COAT.
The coating can reflect infrared radiation, the portion ofthe solar radiation with strong heating effects, through acombination of special heat reflecting pigment that offers
high reflectance and hollow ceramic microspheres that
effectively reflect infrared radiation. It reduces theincrease in road surface temperatures during the day andsuppresses radiant heat at night.

The Solar heat-blocking coating layer reflects near-infrared
radiation, thereby suppressing pavement heating.
This prevents rising temperatures and heat accumulation.

Reflective properties

The pavement absorbs and accumulates solar radiation;
as it does so, surface temperatures increase. The hot pavement
heats the surrounding air and during the night, releases theaccumulated heat and makes nights even warmer.

PERFECT COOL features low reflectance in the visible
range but has much higher reflectance properties thannormal paint or asphalt in the infrared range. Thus, while
it may appear the same to the human eye, it is capable ofsuppressing increases in road surface temperature.

NIPPO’s unique heat-blocking technology suppresses
increases in road surface temperature by about 10°Cor more.
Improve ambient conditions in summer time.

The effects of PERFECT COOL are obvious when you compare thermographic
images of PERFECT COOL pavement (left) and normal pavement (right).

Example of road surface temperature

Reduces road wear by traffic by 50%, thereby
doubling pavement life. Suppresses loss of aggregate
from permeable pavement. (PERFECT COOL M/ML)
Requires no additional costs after the initialinvestment.
Requires no maintenance, such as water spraying.
Increases visibility and improves safety.
Suits the surrounding environment or a specificpurpose, with different versions of the product tochoose from.
Compatible with a wide range of pavement types,including permeable pavement.

Compared to normal pavement, road surface temperatures are approximately
12°C lower during the day and 3°C at night.
