Powder coating for radiator in Shandong Province

   The powder coatings for radiators in Shandong Province tend to agglomerate at a certain temperature, which is mainly due to the softening of resins leveling agents. Thermosetting powder coating is an organic polymer with low molecular weight. This kind of resin itself has a kind of physical properties. At a lower temperature, the hard brittle glass state will appear. When the temperature rises to a certain degree, the resin will change into a certain elasticity adhesion state. Below this temperature, the resin will return to the glass state. The temperature at which the glass state viscoelastic state of the resin change mutually is called the glass transition temperature of the resin.
