Let us powder coating manufacturers tell you why powder coatings clump.

Reason

Powder coatings have a tendency to clump at a certain temperature, mainly due to the softening of materials such as resins and leveling agents in the powder coating when exposed to heat. Powder coatings are all thermosetting powder coatings, where the resin used as the main film-forming material is a low molecular weight organic polymer. These resins have a physical property that, at lower temperatures, they exhibit a hard and brittle glassy state. When the temperature rises to a certain degree, the resin begins to transform into a state with a certain degree of elasticity and adhesion. Below this temperature, the resin returns to a non adhesive glassy state. The temperature at which the glassy and viscoelastic states of the resin transition to each other is called the resin's glass transition temperature.
