Abstract

Barnices termocrómicos, procedimiento para su preparación y su utilización como termoindicador, constituidos por barniz transparente en una proporción comprendida entre el 1 y el 99% en volumen y por disoluciones de poli(3-alquiltiofenos) en una proporción, en volumen, comprendida entre el 99% y el 1%. Estos barnices termocrómicos presentan unas propiedades de tiempo de secado y dureza típicas de los barnices convencionales incorporando además la propiedad, una vez aplicados, de cambiar reversiblemente de color en torno a una temperatura característica. Estos nuevos barnices son apropiados para la preparación de recubrimientos termoindicadores, ya que proporcionan una medida orientativa y rápida de la temperatura del substrato sobre el que están aplicados a través del color que presentan. Tales recubrimientos son especialmente útiles para aquellos procesos industriales que requieren un indicador visual de la temperatura a la que se encuentra una determinada pieza, aparato, equipo, etc. De aplicación en recubrimientos.Thermochromic varnishes, a procedure for its preparation and use as a thermo-indicator, consisting of transparent varnish in a proportion between 1 and 99% by volume and by solutions of poly (3-alkylthiophenes) in a proportion, in volume, between 99% and 1%. These thermochromic varnishes have drying and hardness time properties typical of conventional varnishes, also incorporating the property, once applied, of reversibly changing color around a characteristic temperature. These new varnishes are suitable for the preparation of thermo-indicating coatings, since they provide a quick and approximate measurement of the temperature of the substrate on which they are applied through the color they present. Such coatings are especially useful for those industrial processes that require a visual indicator of the temperature at which a certain part, apparatus, equipment, etc. is located. Application in coatings.
