There has been a century of change from where the cure times of automotive finishes progressed from weeks, to days, to cure times of less than one hour. At the same time, overall product quality greatly improved, and the amount of solvent used has steadily decreased, which is an improvement for the environment.
The latest industry breakthrough is UV cure paint films. With this new technology, UV energy is used to catalyze the paint film. UV light initiates and sustains the cross-linking reaction, which leads to the through-cure of a high quality paint film in just minutes.
