PAINT FOR APPLICATION OF SPECTRAL-SELECTIVE COATINGS AND METHOD OF PREPARING THE SAME, SOLAR HEAT ABSORBING DEVICE AND SOLAR COLLECTOR CONTAINING SUCH A DEVICE.

摘要

An inexpensive and easily used paint for applying spectral-selective coatings consists of spectral-selective pigment, reflective metal particles, binder and, if desired, other components with or without a liquid vehicle, the spectral-selective pigment being combined with a binder and, if desired, a liquid vehicle, and the reflective metal particles being added to the resulting pigment dispersion. A coating of the paint on a base provides a solar heat absorbing device for use in a solar collector.
