Coatings are essential in various applications like car paint, marine coatings, coatings on wood and plastics, and architectural protection. However, solar irradiance, heat, and especially water induce microscopic ageing processes that with time lead to macroscopic changes like yellowing, color change, cracking, gloss loss, or delamination.
There are many xenon and UV fluorescent standards available for durability testing  of paints and coatings. Selecting the right laboratory and outdoor test standards for the specific application, is critical to prevent premature failures. 

In this Guide you learn about:

  • Stress factors and failure modes
  • Natural and laboratory weathering
  • Xenon-arc and UV-fluorescent tests
  • Standards for various applications
