Course Description

This comprehensive two-part course will help you solve any of your coating film defects faster (pinholes, orange peel...) by understanding their root causes and how to prevent them using smart science.

Expert Jochum Beetsma will address the reasons of such defects, with easy-to-apply solutions & cost-effective formulation strategies.

What to expect in this two-part course?

  • Part 1 (90 min)- Understand basic physical chemistry & analyze the causes of defects (pigment mobility, gradients in surface tension...)
  • Part 2 (90 min)- Find practical solutions for each real-life case (more thinking, less trials)

Why should you view this course?

Film defects (e.g., levelling, orange peel, pinholing, floating…) can ruin both the protective and aesthetic properties of coatings. Relying on a trial-and-error approach can waste precious time! Take cratering and crawling, for instance: they look alike but require different solutions. Join this course and:

  1. Resolve your film defects faster by correctly identifying the issue (cratering, pinholing, crawling, floating…) and understanding its root causes.

  2. Learn to prevent film coating problems by applying physical chemistry principles effectively (Gibbs energy, surface tension, etc.).

  3. Develop simpler, more cost-effective formulations by avoiding unnecessary additives in your paint or ink system.
