This e-Training Course will help you optimize interfacial tensions in your waterborne coatings and inks in order to prevent & solve issues induced by inadequate liquid / solid surface tension (pigment dispersion, leveling...).

Johan Bieleman will share his practical experience on how to select the right chemistry, define the optimal loading and combine various additives for maximum synergy & simplicity.

5 reasons to attend this online course:
Reason 1 Save time selecting surfactants (polysiloxanes, polyfluorsurfactants...) with a detailed review of their pros & cons by an expert in additives

Reason 2 Reduce costs of your WB coatings and inks by adjusting variety and loadings of additives used to reach targeted performance

Reason 3 Achieve better balance in paint properties (wetting, adhesion, leveling, film appearance...) by efficiently controling tensions at different interfaces

Reason 4 Troubleshoot less by understanding how to deal with high number of additives (wetting agents, defoamers, thickeners...) & minimize side-effects

Reason 5 Get expert insight for your own projects by interacting with Johan Bieleman during the Q&A session

COURSE TYPE: Advanced Formulation
Ideally suited for:
  • Formulators of waterborne paints, inks and related products (and those switching from solvent based coatings)
  • Technicians involved with the development or testing of raw materials for such systems
  • Engineers, scientists and managers responsible for formulating and developing ingredients


    • Prerequisite: Working knowledge in WB coatings and inks formulation is recommended to fully benefit from this course


    WHAT YOU WILL TAKE AWAY FROM THIS COURSE:
    Formulating waterborne systems requires the use of plenty of additives (wetting agents, levelers, associative thickeners, defoamers...) and it is often difficult to find the right balance in composition to achieve desired performance while minimizing side-effects.

    With the structured review on interfacial tension control for waterborne systems provided by this practical course, attendees will come away with enhanced autonomy & efficiency in their coatings & inks formulation work.

    They will be able to select additives on solid grounds rather than just trusting suppliers recommendations and to play with their formulation (composition & loadings) to achieve / adjust performance.

    Early Registrants: Submit your specific needs when registering and let Johan Bieleman help you find appropriate solutions.

    The following sections will be covered during this session:

      1. Introduction (why surfactants are essential ingredients in a waterborne paint)

      2. How surfactants help influence performance, cost and quality

      3. Fundamentals of Surface Tension

      4. Review of Surfactant families (benefits & drawbacks)
      a) Organic hydrocarbon based surfactants
      1.1: sulphates, sulphonates
      1.2: sulphosuccinates
      1.3: phosphate esters
      1.4: carboxylates
      1.5: polyols
      1.6: quats, various
      b) Polysiloxanes
      c) Polyfluorsurfactants

      5. Pigment wetting

      6. Side effects: Film defects and surface control

      7. Side effects: Foaming and Defoaming

      8. Optimizing surfactant usage for cost efficiency & reduction of side-effects

      9. Summary

    At the end of the training there will be a Q&A Session where you can pose questions to Johan Bieleman. A transcript of all the questions and answers will be made available after the event.
