Polyester Resins for Powder Coatings
FINEDIC products are resins for powder coatings. Powder coatings are coatings in a powder state that do not contain solvents like organic solvents or water in the coating. Polyester resins are highly evaluated as environmentally-friendly coatings because they do not release VOCs when forming coating films and they can be recovered and reused. DIC features the lineup of polyester resins below matched to various types of curing agents.
For blocked isocyanate curing, DIC stocks various hydroxyl-terminated polyester resins suited to demanded performance such as weather resistance, mechanical properties, and workability. For epoxy-cured and HAA (hydroxyalkyl amide) curing, DIC stocks many acid-terminated polyester resins.
For acrylic polyester composite curing, polyester resins are valued on such points like being able to easily control gloss using DIC's unique curing techniques, and their record of use in markets is continuing to increase.
