I'm curious how thermochromatic paint is made that has many changing colors corresponding to different temperatures? Read that liquid crystals are used but they same as in LCD displays or it's somekind another chemical?
sauroman1 said:I can't find liquid crystal based paints in online shops. I mean thermochromatic not those with just two colors but LC which have beautiful rainbow colors corresponding to minute temperature changes.
Thermochromatic rainbow paint is made with temperature-sensitive pigments that change color when exposed to heat. These pigments contain liquid crystals that are arranged in a specific pattern. When the temperature changes, the crystals move and reflect light in different ways, resulting in a change of color.
The main ingredients in thermochromatic rainbow paint are temperature-sensitive pigments, binders, and solvents. The pigments are responsible for changing color, while the binders and solvents help to create a smooth and durable paint that can be applied to surfaces.
The color range of thermochromatic rainbow paint is determined by the type and amount of temperature-sensitive pigments used in the paint. Different pigments have different temperature ranges and can produce a variety of colors. The amount of pigment used also affects the intensity and range of colors.
Yes, thermochromatic rainbow paint is safe for indoor use as it is non-toxic and does not contain any harmful chemicals. However, it is important to follow the manufacturer's instructions for proper usage and ventilation.
Thermochromatic rainbow paint can be used on a variety of surfaces, including walls, wood, fabric, and paper. However, it is recommended to test a small area first to ensure compatibility and adhesion. Smooth, non-porous surfaces may require a primer before painting for better adhesion.
