The sun's rays are divided into ultraviolet ray, visible ray and infrared ray.Ultraviolet ray functions chemically such as sterilization, and visible ray is light which is recognized, mainly called sun light. Infrared ray is related with bioaction having about 0.78μm~1000μm of wavelength and it is divided into near-infrared ray which is near visible ray and far-infrared ray which has longer wavelength. There are many classifying ways by theory, but generally, it is classified into near-infrared of 0.78μm~3μm, mid-infrared of 3μm~6μm, far-infrared of 6μm~15μm and extreme infrared of 15μm~1000μm.
The effects of radiation of far infrared are as the followings.

It blocks hexavalent chromium which is one of induction substances of atopy in cement so act as a relaxant of atopy symptoms.
Humidity control capacity of soil has functionality 3 times of general cement, and it may absorb moisture when house is wet and release moisture when house is dry.
Put 55~60% water compared with weight of material into ARA powder container, stir it and apply it using roller, brush or airless gun. There is no smell so it can live on the construction day.
