Solving Film Coating Defects Part-2

This is a Past Course

Recorded on Oct 11, 2017

Solve faster any of your paint defects (craters, pinholes, orange peel...) and learn to prevent them using smart science (less unfocussed trials). 

Jochum Beetsma will help you analyze the root causes of film defects (pigment mobility, solvent separation, gradients in surface tension...) and share practical solutions for each case (more thinking, less trials).

Why should you view this course?

Cratering, pinholing, crawling, floating… With a trial and error method, any paint coating defect has the power to waste your time! Take cratering and crawling: 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
Solving Film Defect

Who should view this course?

Coatings and Inks formulators / developers with a need to solve & prevent film coating defects faster by better applying science behind film defects.

    This course was very useful to understand why defects occur and what way to try to solve them.

    Hong X. , from Cardolite Corporation

    Excellent course! Simple, sound and clear advice. Hint on how to solve some cases I face.

    Francis M. , from SEPAD

    Very good fundamental review with some specific examples.

    Tryg J. , from Carestream

    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

    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.

    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.
