Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue of Coatings entitled “Coatings for Building Applications”.

The protection of buildings with smart coatings has long been a challenge for the coating industry, due to the impact of pollutants and synergism of climate parameters, intensively affecting the building façade. Into this framework, research activities were addressed and focused on self-cleaning, hydrophobic, and super-hydrophobic coatings, exhibiting durability to the environmental loading and compatibility to the building substrate. Recent advantages in nanoscience have resulted in the establishment of smart materials with multifunctional properties, such as self-cleaning, self-healing, antifungal, biocidal, super-hydrophobic, anti-graffiti, breathable paints, energy-efficient paints, renders with nano-additives, etc. Nanostructured coatings could accomplish more than one of the above-mentioned desired functionalities and therefore could be considered as powerful suggestions for building protection and a clean environment. In this Special Issue, contributions on the above topics will be welcomed, and authors are encouraged to submit their works concerning inorganic and organic coatings with specific properties addressing both building and environment protection.

The topics of interest include but are not limited to the following:

  • Photocatalytic and self-cleaning coatings;
  • Hydrophobic, super-hydrophobic, and water/oil repellent actions;
  • Coatings with biocidal and antifungal functions;
  • Anti-graffiti properties;
  • Energy-efficient paints;
  • Renders with nano-additives;
  • Coatings with CO2 sequestration action.

This study aims to evaluate the difference in thermal behavior among paints with the presence of traditional and NIR pigments by means of a simple and cheap laboratory-scale test. Considering these goals, the thermal and esthetical properties of two different cool coatings were assessed, highlighting their positive and limited aspects. Two different complex near-infrared inorganic reflective (NIR) pigments with yellow and black respectably colors were mixed in an acrylic waterborne copolymer binder. The paint formulations were applied on steel panels. The thermal performance of the coatings was investigated in the NIR-region of the light spectrum by exposing the samples to an IR-lamp. The outer and inner surface temperatures of the painted panels were recorded using thermocouples and an IR camera. The samples were aged by artificial UV-B light exposure. Color and specular gloss changes at different exposure times were evaluated. The behavior of the cool coatings was compared with that of conventional coatings with similar color characteristics. The black cool coating achieved a maximum temperature decrease, compared to the conventional black one, of approximately 12 °C. The stability for the cool coatings was very similar to that of the conventional coating, indicating that black pigment could be a potential candidate for cool-coating applications. The yellow cool coatings did not show a significant decrease in temperature compared to the conventional paint. The gloss and color changes resulted as influenced by the types and amount of pigments.

Radiative cooling is a passive cooling technology that can cool a space without any external energy by reflecting sunlight and radiating heat to the universe. Current reported radiative cooling techniques can present good outside test results, however, manufacturing an efficient radiative material which can be applied to the market for large-scale application is still a huge challenge. Here, an effective radiative cooling coating with a near-ideal selective emissive spectrum is prepared based on the molecular vibrations of SiOx, mica, rare earth silicate, and molybdate functional nanoparticles. The radiative cooling coating can theoretically cool 45 °C below the ambient temperature in the nighttime. Polyethylene terephthalate (PET) aluminized film was selected as the coating substrate for its flexibility, low cost, and extensive production. As opposed to the usual investigations that measure the substrate temperature, the radiative cooling coating was made into a cubic box to test its space cooling performance on a rooftop. Results showed that a temperature reduction of 4 ± 0.5 °C was obtained in the nighttime and 1 ± 0.2 °C was achieved in the daytime. Furthermore, the radiative cooling coating is resistant to weathering, fouling, and ultraviolet radiation, and is capable of self-cleaning due to its hydrophobicity. This practical coating may have a significant impact on global energy consumption. Full article
