Abstract
Thermosetting powder coating compositions comprising cellulose butyrate having a butyryl content of from about 35% to about 55% by weight, a hydroxyl content of from about 0.5% to about 3.0% by weight, and a viscosity of from about 0.05 to about 1.0 second are disclosed. The composition further comprises a crosslinking agent and a catalyst which allows the powder to flow out prior to fusion. Coatings formed by this composition have excellent physical properties and appearance.
