The photo above is a micrograph of a water droplet (5Êl) during the water-repellency
test for gTAMAGAMI.h When the water is absorbed by the paper, it usually can not
keep its globe- shape. In this photo, you can see that the droplet has
not soaked into the paper and has kept the fine globe-shape on the surface.
The reflection on the droplet is the reflection of the light we used to
take the photo. The outer ring is the original reflection of the light.
By the reflection passing through the droplet in an instant, the inner
ring, is the product of the reverse reflection of the outer ring, was created.
As a result, we can see the double rings of the light reflection on the
droplet which is just like the eye of a human being. By analyzing how precise
the rings are, it is proved that the droplet is in its perfect globe-shape.
This is proof of the high water-repellency of gTAMAGAMI.h
The photo on the left is a micrograph of a water droplet during the water-repellency test under the same condition as above for the washi paper which is not coated with our super high water-repellent. The instant the water came in contact with the paper, the water began to soak into the paper. You can clearly see this by observing the shape of rings of the light reflection on the droplet.
