Resins and Curatives: The Binder System for Thermosetting Powder Coatings
Winter 2000 Vol. 2, No. 1
Ideally, appearance and other properties of a powder coating should be equivalent to those of a liquid coating of the same thickness. However, the unique requirements of a thermosetting powder coating impose restrictions on the binder system (the resins and curatives), making this difficult to achieve.
While liquid paint and powder coatings are similar in many respects, the technology used to prepare them is markedly different:
