: Over 2 million tonnes of unsaturated polyester resins are consumed annually for applications ranging from high-specification automotive components to waterproofing linings for marine and construction sectors. Resins For Surface Coatings. Alkyds & Polyesters [PDF]

Alkyds are the dominant binders in commercial oil-based coatings. They are technically polyesters modified with natural oils or fatty acids, which grants them their signature ease of application. Resins for Surface Coatings. Alkyds & Polyesters

: They offer superior mechanical properties, including high impact and abrasion resistance, alongside excellent aesthetic texture. : Over 2 million tonnes of unsaturated polyester

Often referred to as , polyester resins are synthetic polymers where monomers are joined by ester bonds without the addition of fatty acids. They are technically polyesters modified with natural oils

: Typically composed of roughly 60% fatty acids (e.g., soybean, linseed, or tung oil), 20% pentaerythritol, and 20% phthalic anhydride.
