Thermochromic Material

Thermochromic (thermotropic) dimming material is a type of liquid composed of various components such as organic monomers, crosslinking agents, plasticizers, salts, and photoinitiators. After being cured by ultraviolet light, they form elastic functional films with temperature-sensitive characteristics: when the ambient temperature is below its critical transition temperature, the functional film appears transparent; when the temperature exceeds this threshold, it transitions to an opaque frosted state. Applying this temperature sensitivity to architectural glass can achieve significant energy-saving effects, while also enhancing the technological and aesthetic qualities of the building.
