Term: ultraviolet

Definition of “ultraviolet” by Brushworks Painting: Ultraviolet (UV) refers to a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays. It falls in the range of approximately 10 to 400 nanometers on the electromagnetic spectrum.
In practical terms, ultraviolet light is invisible to the human eye, but it has significant effects in various fields:

In painting and coatings, UV radiation can cause fading, chalking, and degradation of paint films, especially on exterior surfaces exposed to sunlight.
UV-resistant paints and coatings are formulated to withstand prolonged exposure to sunlight, helping to maintain colour and finish over time.
In health and safety, prolonged exposure to UV rays can damage skin and eyes, so proper protective measures are important when working outdoors.

In summary, ultraviolet refers to a form of light energy that, while invisible, plays a crucial role in both the deterioration and protection of painted surfaces.
