An alkyd is a polyester resin modified by the addition of fatty acids and other components. [1] Alkyds are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils .

alkyd resin, a complex oil-modified polyester that serves as the film-forming agent in some paints and clear coatings. Developed in the 1920s, alkyd-based enamel paints were once one of the most important types of surface coating.

2020年2月13日 · An alkyd is an ester-based polymer derived from the polycondensation reaction of a polyhydric alcohol and a polybasic acid. In addition to these ingredients, the resulting resin is modified with an oil or a fatty acid to make it more flexible and to air harden it.

Alkyd resins are thermoset polyesters obtained through the reaction between an acid (or an anhydride) and an alcohol. Among the polyhydric alcohols used in the reaction of polyesterification are the glycerin and pentaerythritol.

2024年8月21日 · Alkyd resins are a type of synthetic resin widely used in manufacturing coatings, paints, and varnishes. Its ability to provide durable, glossy finishes with excellent adhesion makes it a preferred choice for various applications, from architectural to industrial coatings.

2016年3月4日 · Although alkyds are no longer the largest volume resin type used in coatings, they still play a significant role in the coatings industry, not only because of their versatility, but also because they employ a significant amount of renewable material. The term alkyd is derived from alcohol and acid.

2024年6月28日 · Alkyds, or alkyd resins, are polyester resins modified by the addition of fatty acids and other components. These synthetic resins are known for their excellent binding properties, making them a popular choice in the production of …

2022年4月6日 · What is an Alkyd Resin? An alkyd is an ester-based polymer resin that’s modified (modified alkyd resin) by adding fatty acids or other oils. They are the predominant binder in most commercial oil-based coatings. The resin is flexible, glossy, quick-drying, and less prone to chipping, making it ideal for paints, varnishes (stains), and ...

Alkyd Resin: Properties, Applications, and Industry Insights. Alkyd resin represents a crucial class of polyester resins that have been extensively utilized in various industries for over eight decades.
