An alkyd resin is a polyester resin modified by the addition of fatty acids and other components. Alkyd resins are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils. Mostly alkyds are used in automotive refinishing enamels and the linseed based alkyds are also used in general purpose industrial air drying enamels.
Alkyd resins can be regarded as a class of modified condensation polymers. Originally, alkyd resins were merely the reaction products of phthalic anhydride and glycerin, and were too brittle to make satisfactory coatings. However, the use of fatty oils or unsaturated fatty acids in combination with the brittle alkyds resulted in flexible, glossy, air-drying coatings, which at the time of discovery revolutionized the chemical coating industry. Still today, surface coatings based on alkyd resins as film formers continue to be one of the largest types of coatings used in the world.
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 commercial oil-based coatings. Alkyd resins are a staple ingredient in most synthetic paints, varnishes, and enamels. Around 200,000 tons of alkyd resins are produced each year and used as coatings and finishes in the protective coatings industry.

Products made with alkyd resins can be to protect metal, wood, or concrete from weather and natural wear and tear. In addition, coating a structure with an alkyd resin-based product can help prolong its lifespan. Orson is one of the best alkyd resin manufacturers in India.
This complex oil-modified polyester acts as a film-forming agent in some paints and clear coatings. The different types of alkyds you use will depend on what you’re trying to protect. You’ll often find alkyd resin used in exterior painting products or in stains (varnish). Why? Because they’re durable, resilient, and offer a high-quality finish with excellent protection. Alkyd coatings are water-resistant, and they can adhere to various materials like wood or metal.
