Solving Adhesion Issues of Coatings & Inks

113 Day(s) left to register

Wednesday Oct 9, 2024

Avoid failure cases! Quickly tackle real-life coatings adhesion issues (weak boundary layers, poor wetting, insufficient roughness, lack of strong interactions & stress...) and troubleshoot them with expert solutions.

Expert consultant - Jochum Beetsma, will focus on the key aspects of coatings adhesion (wetting process, film formation, adhesion mechanisms & the influence of additives...). Surface pre-treatment for different substrates (plastics, metals, wood…) and test methods will also be discussed.

Why should you attend?

Ensuring proper adhesion between coatings and various substrates (wood, metals, plastics and mineral substrates) continues to be one of the most critical challenges. Whether it is strong shrinkage seen within the coating itself or low surface energy of the substrate’s surface, multiple factors can negatively influence adhesion.

Simultaneously, applying incorrect methodologies will waste your time in resolving adhesion issues (poor wetting, insufficient roughness, lack of interactions & weak boundary layers...). Speed up by joining this online course and:

  1. Be quick to detect factors disturbing your coating adhesion by reviewing key adhesion mechanisms (intermolecular interactions, diffusion, surface roughness, penetration and interfacial crosslinking).

  2. Troubleshoot faster by reviewing compatible fix (pre-treatment & additives) based on root causes analysis.

  3. Gain understanding of how to measure adhesion using pull-off & cross-cut test.

  4. Get expert guidance to solve your own adhesion challenges based on real-life examples.

Who should attend?

Experienced developers, formulators, producers and users of coatings, inks and related systems (waterborne, solvent-based, high solids, melts and powder coatings) for application on different substrates (wood, metals, plastics & mineral substrates...).

Course Outline

  • Importance of wetting and spreading: surface tension, surface energy, pre-treatment & additives.

  • Pre-conditions in order to achieve adhesion: complete wetting, surface roughness, adjustment of interactions and prevention of stress (caused by shrinkage).

  • Influence of additives on adhesion: wetting agents, adhesion promoters and release agents.

  • Understanding of adhesion mechanisms: intermolecular interactions (hydrogen bonding), diffusion, penetration, mechanical anchoring & covalent bonding.

  • Main causes & their solutions for adhesive failure: additives, stress, substitution, hydrophobicity, dirt, smoothness and weak boundary layers.

  • How to measure adhesion: pull-off test & cross-cut test.

  • Every day problems associated with intercoat adhesion.

  • 30 Mins Q&A session- Interact live, put across your formulation queries to the expert !

    All these points will be illustrated with REAL LIFE EXAMPLES (wood coating system, cohesive failure, improve adhesion on plastic and covalent bonding with metal).
