Alkyd Resin (Long Resin) are saturated polyester resins modified with fatty acids, which have high flexibility and low viscosity. The word Alkyd, which has been changed to Alcid, is made up of the words “L” meaning alcohol and “Kid” meaning acid. However, some sources believe that the word is made up of the words alcohol and anhydride.
What is a Alkyd Resin (Long Resin) ?
Alkyd resins are formed by the reaction of an oil (fatty acid), a polyunsaturated alcohol (polyL) and a polyunsaturated acid or anhydride. In fact, alkyd resin is a polyester in which there is a capacity for fatty acids.
feature Alkyd Resin (Long Resin) ?
Long resin is a hard and brittle polyester, but the fatty acid (or oil) in its chain has improved the flexibility and durability of the paint, its moisturizing properties, and its ability to adhere to the surface, prolonging its drying time. In this material, due to the presence of ester groups, we see polarity, which is different from the amount of fatty acids used in it. The lower the amount of oil used, the polar it is and the better the adhesion.
Alkyd resins are very resistant to corrosive environments; Low sulfuric acid vapors or dilute acid sprays do not have much effect on the quality and durability of these paints, but if the acid concentration increases, these paints will have no resistance.
Application of Alkyd Resin ?
A wide range of applications and features for alkyd resin can be considered as one of the most widely used resins in the paint and resin industries, but they are generally known as resins used in construction and decorative oil paints, and these materials can also be considered It also used urea formaldehyde and In traffic colors
