Types of thermochromic pigments:
Thermal achromatic type: colored state at low temperature, when the temperature rises to the set value, the pigment changes from colored to colorless. Its color change temperature can be set in the range of -20 ~ 70 ° C according to user needs: The R series color-changing pigments have the most varieties, complete chromatography, and are the most commonly used color-changing pigments.
Hot hair color type: its color ~ temperature characteristics are opposite to the R series. It is colorless at low temperature, and the pigment changes from colorless to colored when the temperature rises to the set value. Its color temperature range is: 60 ~ 65℃.
Other key words: up converting pigment, IR phosphor, infrared ray active pigment
Infrared phosphor is mainly composed of rare earth inorganic substance (non-toxic and non-radioactive), which does not show color in sunlight and sunlight. It is colorless and transparent, and displays dazzling light when it is irradiated by the infrared ray of 940~1060mm (peak value 980mm). This paint temperature tolerance is wonderful, 60 ° c (long-term) to 800 ° c (2 hours) performance remains the same.
The Photochromic pigment is a photochromic powder material made by wrapping the reverse photochromic dye in the microcapsule. The product improves the solubility of OP oil, allowing it to be uniformly dispersed in water-based systems. MC is white in an indoor light source environment and becomes the color of a dye under ultraviolet or sunlight. It can be added directly to the appropriate application for use. The average particle size of the photosensitive microcapsule powder is 3-10μm, which is a microcapsule powder containing 2% to 5% of the photochromic powder, and the moisture content is ≦3%. Suitable for water-based, oil-based ink, paint and plastic injection, extrusion Photosensitive microcapsule powder is a pigment, characterized by bright color, high temperature resistance and solvent resistance, which can be used in plastic injection, oily ink and paint.
