RAL1005 honey yellow electrostatic thermoset powder coating with high mechanical property
Powder coatings are applied to metal substrates to form highly durable and attractive finishes. They are manufactured and applied without the use of organic solvents; thus, they are highly desirable from an ecological standpoint. Most of the current interest in industrial powder coating technology is in formulations based on thermosetting resin binders, predominantly epoxies and polyesters (saturated types with carboxyl or hydroxyl functional groups). Epoxies are preferred for their overall physical properties, while polyesters exhibit better outdoor weathering properties. This report focuses on powder coatings based on thermosetting resins and discusses only the electrostatic spray method of application. Most of the interest in powder coatings and their best prospects for growth involve these technologies. The major thermosetting powder coatings are based on four chemistries: epoxy, polyester, urethane and acrylic.
