Chemistry and chemical engineering
Alkyd paints are based on alkyd resin precursors, which are polyesters incorporating unsaturated fatty acid chains such as oleic acid, linoleic acid, linolenic acid, and ricinoleic acid. In the drying process of a paint film, the solvent evaporates (physical drying), and then chemical reactions take place, resulting in the curing of the binder.
