Thermochromic Pigment - Thermochromic pigment for thermochromic Paint Thermochromic Ink Thermochromic Fabric – Topwell
Introduction Themochromic pigments are composed of micro-capsules that change color reversibly. When the temperature is raised to a specified temperature the pigment goes from colored to colorless (or from one color to another color). The color returns to original color as the pigment is cooled down. Processing temperature The processing temperature should be controlled below 200 ℃, the maximum should not exceed 230 ℃, heating time and minimize material. (High temperature, prolonged heating... -
