≪Principle of a tough coat≫

When a sunbeam is cross with painted film, the part of the infrared rays in it is changed to heat energy, and it disperses and moves in the pai-lou skin. Painted film includes the strong special material for heat exchanges, and as soon as it touches this, energy exchange occurs. Almost all of heat is consumed as kinetic energy to get up at a surface. If it's this principle, the absorption color of the heat (the dark color) and a problem of dirt on a surface are also settled.

≪As an application in detail.≫

1. Dark painting wrap is possible.
   
2. The surface is tainted and damaged, and even if it wears away, the radiation effect doesn't fall.
   
3. I don't reflect by heat, so there is little reflected heat. It's suitable for a sidewalk, a poolside and a radiant heat measure on a stand floor.
   
4. It's lusterless originally, so cheap and broad resin is available.

There isn't heat exchange paint using conventional reflection of heat shielding paint and plan of heat insulation.

The feature and the merit

It's possible to lower the temperature of the paintable surface more than 10 ℃ compared with general heat shielding paint.

 Tough coat< comparison in the D-42/D-47> painting part, the heat shielding paint painting part and non-painting part

 Heat measure in school school grounds of a all-weather pavement< a problem of conventional cold burn occurrence is canceled.>
Of use and heat of a tough coat, it's possible to block off and move by a bare foot through the year.
A possibility also spreads over a roof and a poolside.

==Principal's word==

Background of environmental improvement in school grounds
Non-land Hitoshi Masashi of the surface pavement in school grounds was repaired at a main school in summer of 2006. "The bad of the drainage" was the reason that repair is biggest, but the one I wanted to settle another was to block heat off.
When I became barefooted, and group gymnastics and a dance of people were practiced in September before an athletic meet at the former school grounds, I had got a blister of a cold burn on children's sole. I had no choice but to put on shoes on the day which is mostly sunny reluctantly. So that it was introduced when I consulted charge of facilities for School Board, "tough coat" came. And children used this "tough coat" only inside of the truck which runs.

In reduction in differential temperature in the temperature rise test, the effect

A repair work of school grounds has ended safely. On a day hot for summer, it's possible to sense the temperature difference with the place where "tough coat" was applied and the place I gave a coat of ordinary paint. Every time I walked, you could realize "Oh, a way inside the school grounds wasn't hot.", so it was interestingly and I went back and forth many times.
Children also sit down on school grounds by a day hot for summer and lie. Group gymnastics and a dance of people could be done now barefoot surely by an athletic meet. It's possible to walk barefoot at any time of the year around. Moreover from a way of the soccer team using school grounds from the evening and a tennis club, "daytime heat isn't left so much it's comfortable.", is it?, I have impressions.

Differential temperature in the temperature rise test is restrained, it's possible to reduce the electricity charges by which it's for air-conditioning equipment to work. The energy conservation and the ecology technology which also lead to reduction in CO2 and relaxation in a heat island.

Not to change and to continue the effect, even if dirt is adherent, it's also excellent in a cost side.

 I play an active part by a topping and a parking lot in a roof, a roof, an outer wall, a floor, a poolside, a bridge, a ground, school grounds and a park. It's effective at the place where the sun is strong in particular.
