Optical Characterization of Coatings Based on Microspheres and Evaluation of their Application for Energy Control

Caracterización Óptica de Recubrimientos Basados en Microesferas y Evaluación de su Aplicación para el Control Energético

The purpose of this research is to perform the optical characterization of microsphere-based coatings for application in energy control, evaluating materials from two manufacturers: Gaina (Kawaguchi Steel Industry Limited, Tosu shi Japan) and Thermo-facades (Suberlev, Castellón Spain).

The methodology used is experimental deductive, for which nanotechnology equipment was used considering the areas for spectrometry and ultraviolet visible (UV-Vis) spectrophotometry in the spectrum ranges between 190 and 400 nm, visible and near infrared (Vis-NIR) in the spectrum range from 400 to 900 nm and Fourier transform infrared spectrometry (FTIR), covering both the middle infrared (MIR) and the near infrared (NIR), in order to obtain reflectance measurements in the solar spectrum (from 250nm - 30000nm). The comparison method used is that described by the ASTM E903: 2012 standard "Standard test method for solar absorbance, reflectance and transmittance of materials by using integrated spheres". The values ​​obtained from the reflectance and spectral absorbance variables of the samples used are within the ranges allowed as thermal coating and contribute to energy efficiency in the housing and building sectors.
