This technology uses the low-carbon geopolymer material & high emission powder to make the passive radiative cooling inorganic coating. Besides, all raw materials are from easily-gained ore or industrial by-products, and the multi-color appearance is also developed. Notably, for decreasing the heat island effect, this coating is feasible to transmit heat into radiation that can be throughout the atmosphere.

1.此技術使用無機聚合材料製成無機塗料，低耗能且低碳排放。
2.此技術所使用原料主要來自於天然礦石及工業副產品，成本低且取得容易。
3.此技術製成簡單，只需將鹼性配方液與粉體攪拌即可塗裝，操作簡單便利。
4.此技術製成之塗料非單一顏色，應用領域更廣。
5.此技術製成之塗料塗裝於水泥或灰砂等基層上可與其產生化學反應，附著力極佳。
6.此技術製成之無機塗料其耐老化、耐生物侵蝕、耐高溫、疏水、抗龜裂等特性優於一般有機塗料。
7.此技術製成之塗料能將建築物/道路鋪面之熱不論晝夜以輻射形式將熱傳遞至太空，避免熱受困於大氣層內使環境溫度上升，繼而降地能源消耗同時減緩熱島效應。

This technology is applied to exterior of buildings and pavements. By means of that, the internal heat can be radiated day and night to the outside and through the atmosphere. Afterwards, the urban energy consumption will decline and protect the environment. Meanwhile, the merits of this technology, such as low cost, easy making, multi-color and so on, meant the great development potential on practical application.
