Abstract
Traditional paints are exposed to harsh environmental influences like UV rays, oxygen, and water, which cause photo-degradation of the pigments’ colors. This review aims to discuss current research endeavors that could improve the durability of paints in the real-world applications of painting to achieve the desired colorfastness properties. It has become evident that recent research activities indicate that it is not only the chemical structure of organic molecular dye that is important for determining the stability of colors but also their interactions with their binder material systems. Only high-quality pigments with sensitive organic dyes require sophisticated applications from UV Absorbers and Hindered Amine Light Stabilizers (HALS) to ensure some acceptable stability. It explains clearly that UV light triggers the production of free radicals that contribute to the destruction of dye’s color pigments. Moreover, both laboratory-based research work by this paper intends to discuss the effective contributions of nanotechnology in the study of durability. Moreover, it briefly focuses on Nano Dyes and Nano-Encapsulated Colors. Due to their immensely large, exposed surface area, the ingoing UV rays are effectively reflected by the Nanostructure of the tiny particles. This paper intends to clarify the negatively reacting inorganic additives of the Nanostructure, such as Titanium Dioxide (TiO2) and Zinc Oxide (Zn-O), which work as photo-catalysts in such outdoor paints. At Nanoscale we use Graphene Nano plates and other two-dimensional materials which act as a protective barrier against the fading of paints.
