  1. Applications and Selection of Polyester Resins in Industrial Coatings: Powder, Coil, Baking, Packaging, and Metal Coating Scenarios In coating formulation, the key to selecting a resin is determining whether it can meet the critical performance requirements of the intended application. Polyester resins are widely used in powder coatings, coil coatings, industrial baking finishes, packaging coatings, and general industrial ...
  2. Film Formation and Curing Mechanisms of Polyester Resins for Coatings: From Functional Groups and Curing Systems to Crosslinked Networks Polyester resins used in coatings are not a single, uniform category. Different polyester resins vary in resin structure, reactive functional groups, curing-agent type, application method, and final coating-film structure.
  3. Understanding Polyester Resins for Coatings: Structure Design, Key Indicators, and Coating Film Performance In a coating system, the resin is the primary film-forming material that forms a continuous coating film. Pigments, fillers, additives, solvents, or aqueous media can affect application, leveling, appearance, storage stability, and certain end-use properties. However, the hardness, flexibility, ...
  4. Alkyd Resins: From Oil/Fatty-Acid-Modified Polyesters to Autoxidative Drying — Understanding Their Structure and Film-Formation Mechanism Alkyd resins are a class of oil- or fatty-acid-modified polyester resins. They are typically prepared by esterification polycondensation of polyols, polyacids or acid anhydrides, and vegetable oils or fatty acids. The name “alkyd” is derived from alcohol and acid, reflecting the basic ...
