THERMOCHROMIC COATING AND METHOD OF MANUFACTURING THEREOF

摘要

A thermochromic coating that comprises a thermo chromic compound and a polyurea resin. The thermo chromic compound and polyurea resin form a thermochromic layer. The coating optionally has a protective layer containing a resin and a UV-blocking material arranged on top of the thermochromic layer. A reflective layer containing a reflective material is optionally arranged between the thermo chromic layer and the substrate. A thermochromic coating is formed by applying successive reflective, thermochromic, and protective layers on a substrate.
