Red Ink Decomposition Test. Photocatalyst that decomposes organic substances (viruses, bacteria, odors, etc.) when exposed to light.
A diluting red ink (Pilot) with water is applied to the tile coated with PALCCOAT VLAG. Consider the red ink as an organic substance (viruses, fungi, odors, etc.). The light amount is about 500 Lux LED light. This is a test that visualizes the invisible photocatalytic effect.
* Methylene blue is used in the JIS performance test, but in this simple test, methyl red is adopted to make the difference easier to recognize.
