Solving Coating Film Defects in Practice

28 Days left to register

Wednesday Sep 9, 2020

This comprehensive two-day 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-day course?
  • 9th Sept: Part 1 (90 min)- Understand basic physical chemistry & analyze the causes of defects (pigment mobility, gradients in surface tension...)
  • 23rd Sept: Part 2 (90 min)- Find practical solutions for each real-life cases (more thinking, less trials)

Why should you attend?

Film defects (levelling, orange peel, pinholing, floating…) can ruin protective and aesthetical properties of coatings. With trial and error method, these defects have the power to waste your time! Take cratering and crawling for instance: they look alike but do not call for the same solution! Join this course and:

  1. Resolve your film defects faster by identifying correctly the one you have to solve (cratering, pinholing, crawling, floating...) & its root causes

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

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

    Very good fundamental understanding of chemistry behind film defects. Appropriate level in general with a good balance of practical and fundamental understanding.

    Tryg J. , from Carestream

    Excellent course! It gives a real understanding of the causes of the defects.

    Francis M. , from SEPAD

    It was good to see, how simple physical phenomena interact and how gradients are formed even with a homogeneous applied film

    Bernd W. , from Rhein-Chemotechnik

    This very good course covered fundamental concepts given during previous courses, but done so with more hands-on practical examples of how those concepts relate to defects.

    Roger K. , from Eastman Kodak

    Excellent technical content!

    Patrick Y. , from Cabot Corporation

    Good explanation of the physico-chemical phenomenas of different film defects.

    Joel R. , from Folien Fischer AG

    Jochum Beetsma gave very good link between defects and physical chemistry

    Subrahmanya S. , from Asian Paints Ltd.

    This course connects experimental results and observations with the underlying physical science and principles governing coating defects. This is the best discussion of surface energy and surface wetting/dewetting that I have heard.

    Chad K. , from Lexmark International

    The course helped improve my understanding of the cause of coating defects, and has equiped me with the tools to analyse and resolve these problems.

    Christopher J. , from International Paint/Akzonobel

    I gained a better understanding of "cratering" vs "orange peel" I am looking forward to Part 2, to determine the difference between cratering vs. pinholes. and the difference between "hammer finish" vs. "orange peel".

    Gerry G. , from Albany International

    Gave a good insight into some relevant surface issues we are currently having.
