Powder coating

Description

A thermosetting resin preparation used to evenly coat metallic pieces without the use of solvents. Powder coatings were introduced about 1960 but only became popular when solvents were tightly restricted at the end of the twentieth century. Electrodeposition is used to uniformly coat a metal object with the finely ground resin, then heat is used to fuse the particles into a hard, resistant film. The coatings are typically 1-3 mm thick.
