Epoxy coatings find much use to protect mild and other steels due to their excellent protective properties. [43] Change in color, known as yellowing, is a common phenomenon for epoxy materials and is often of concern in art and conservation applications. Epoxy resins yellow with time, even when not exposed to UV radiation.

Epoxy resin is typically used post-1930s and is an indication of modern conservation work. Generally, epoxy is very hard, but unlike shellac it is not brittle. The color of epoxy resin can range from yellow/green to a dark yellow/brown. Yellowing of the resin is an indication of aging.
History of painting – painting is the production of paintings, that is, the practice of applying paint, pigment, color or other medium to a surface (support base, such as paper, canvas, or a wall) with a brush, although other implements, such as knives, sponges, and airbrushes, can be used. The history of painting reaches back in time to ...
A generic epoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen.This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers.
Plastic arts are art forms which involve physical manipulation of a plastic medium, such as clay, wax, paint – or even plastic in the modern sense of the word (a ductile polymer) – to create works of art.
Red acrylic paint squeezed from a tube Example of acrylics applied over each other. Experimental pictures with "floating" [a] acrylic paint Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps.

Today, epoxy and the acrylic types predominate. The description and the generally touted advantages are as follows: Epoxy: Although aliphatic epoxy materials have been used, the majority of EPD epoxy types are based on aromatic epoxy polymers, most commonly based on polymerization of diglycidal ethers of bis phenol A. The polymer backbone may ...
