Semi-glossy finish Sahar paint

Alkyd paint is a polyester modified by the addition of fatty acids. The term alkyd, modified from the original name alcide, refers to a combination of alcohol and organic acids. The fatty acid in this causes a flexible coating to form and the paint to dry.

Alkyd paints are produced in different shades of white to black and are divided into three categories: long, medium and short, depending on the percentage of available drying oil composition:

Long oil alkyd paints contain a high percentage of oil and are generally sold as a medium concentration coating and have a high drying speed.
Medium oil alkyd paints are composed of less oil and a higher percentage of polyester and dry more slowly and are used as high-gloss coatings and wood polishes.
Short oil alkyd paint has a much lower oil content than polyester and therefore is not air dry and only dries by heat.
