Why should you attend?

In coating's industry looks are everything, while photodegradation of paints is an inevitable story. With Automotive OEMs and associated stakeholders giving a guarantee of 10-years for the finish, premature failures during application due to inadequate selection criteria often leads to expensive repainting.


Also, there are other challenges like thinner and cost-effective coatings, environmental compliance, and emerging applications with protection to wide spectrum of UV radiations. All this can be mitigated by selecting the right additives and substrates but the knowledge gathered by formulators is either based on past experiences or suppliers recommendations.


This affects the supply-chain directly consequently affecting the brand's credibility in the market. To bridge this gap join our upcoming course and:    


  • Know the principles of photodegradation process and types of degradation (UV Light and Photo induced).
  • Learn about reactable UVAs & HALS and their associated mechanisms & actions.
  • Understand the right selection criterias for Stabilizers i.e. UVAs and HALS (to meet current market norms and issues).
  • Learn application at different levels and troubleshoot formulations with weathering test methods and evaluation techniques.
