ChromaTemp
This is a microcapsule product with a special thermochromic dye, which changes color according to temperatures. The thermochromic dye causes the change of color by the heat-induced chemical structure change. Since it is very sensitive to the external environment, it is made as a microcapsule-type product for protection and thus its repetitive durability is increased. Thermochromic microcapsule has various colors. Because a temperature for changing color can be adjusted variously, you can properly choose diverse types of product according to colors and temperatures.
Temperature for changing color: 0-70°C
Principle of color change
When heat is applied to thermochromic microcapsule, the substance structure inside the microcapsule changes and consequently its color disappears. At cooling time, the internal substance structure of the microcapsule returns to its original state reversibly, and thus the microcapsule has color.
ChromaTemp Series
ChromaTemp Bichrom
Bichrom dye features the change of color by the structural change in specific condition. Since the dye is very sensitive to the external environment, it is made as a microcapsule type product to extend the period of its repetitive function. The microcapsule with the dye is called Bichrom Microcapsule.
Bichrom Microcapsule has various colors. Because a temperature for changing color can be adjusted, you can properly get diverse types of product according to colors and temperatures.
Difference from the standard ChromaTemp
ChromaTemp changes from being colored to being colorless reversibly. But Bichrom Microcapsule changes from being colored to being colored and thus is applied to wider range of areas.
Temperature for changing color: 0-70°C
Principle of color change
When heat is applied to Bichrom Microcapsule, the substance structure inside the microcapsule changes and consequently its color disappears. At cooling time, the internal substance structure of the microcapsule returns to its original state reversibly, and thus the microcapsule has its original color.
SpyBall Serie Erasable Microcapsule
As a kind of thermochromic microcapsule, SpyBall has a property which its color disappears and recovers in accordance with temperature.
If it exceeds the specific temperature, its colors disappear and then recover below the specific temperature in accordance with chemical structure change of substance within capsule. We can make color disappear in specific part by generating heat caused from friction utilizing this principle, disappeared colors to be recovered by lowering temperature below zero.
Principle of color change
It maintains color changes in the range which is wider than existed thermochromic microcapsule products by using special matrix which induces the change of chemical structure in accordance with temperature.
SpyBall product decolors over 60° or 80° its color disappears, it colors back only under low temperature where there is few possibility of coloring during daily life.
ChromaTemp Rev
Reverse thermochromic microcapsule is a product with thermochromic dye, which reveals it’s a color according to increasing temperature. The reverse thermochromic dye, changes its color by the heat-induced chemical structure change. Since the dye is very sensitive to an external environment, it is made as a microcapsule-type product for protection, enhancing its repetitive durability.
Principle of color change
When heat is applied to reverse thermochromic microcapsule, the substance structure inside the microcapsule changes and the color appears. When cooled down, the microcapsule recovers its original structure, and the color disappears.
Available temperature: 40°, 60°C
