Solving Adhesion Issues of Coatings & Inks (Part 2)

Two-part DISCOUNT: Please remember to tick both parts when registering to benefit from 25% off Part 2.

Early registrant bonus: because it is impossible to cover specific examples for all systems/substrates, feel free to send your own adhesion cases if you would like the expert to integrate them in his presentation – Contact us for more details

The following key aspect of coating adhesion will be covered:

PART 1 - September 27, 2012

Wetting: surface tension, surface energy, spreading and work of adhesion.
Film formation: a solid-liquid interface transforms to a solid-solid interface.
Adhesion mechanisms: mechanical anchoring, diffusion, intermolecular forces, hydrogen bonding and interfacial chemical reactions.
Adhesion aspects of different substrates: wood, plastic, metal and stone-like materials.
Methods of pre-treatment of substrates.
Mechanisms of adhesive failure.

PART 2 - October 11, 2012

Discussion of Case Studies given in Part 1.
Examples: epoxy systems and polyurethane systems.
Issues with intercoat adhesion: the adhesion between two coating layers.
Importance of mechanical properties of coatings with respect to adhesion.
Influence of additives on adhesion.
Main causes for adhesive failure: additives, stress, substitution, hydrophobicity, dirt, smoothness, weak boundary layers and osmosis.
Tests for measuring adhesion of films.
Phenomena closely related to adhesion: easy-to-clean coatings, anti-graffiti and reinforcement of coatings.

At the end of the training there will be a Q&A Session where you can pose questions to Jochum Beetsma.

A transcript of all the questions and answers will be made available after the event.

Fredrik C. , from Teknos Oy:
"Gave a good overall overview on the aspects of adhesion. It is a problem that I encounter many times in my work."

Gustavo B. , from Lorama Inc.:
"Excellent overview and examples, with good logical explanations."

Martin D. , from CAS-MI Laboratories LLC:
"The course very well covered different substrates with case studies. I found useful information on specific treatments involved for the interaction between the substrates and the topcoat/primer interface."

Blistering or flaking inducing metal corrosion, wood dimensional instability, lack of adhesion to plastics… Adhesion-related failures are numerous, costly and can trigger catastrophic consequences. This implies that prevention of damage should start by coating adhesion being foolproof.

You will improve your efficiency at developing new products and troubleshooting existing formulations with an in-depth review of key governing coating adhesion aspects: adsorption, wetting, surface tension, surface energy and wetting agents.

Adhesion of films onto substrates as well as intercoat adhesion will be discussed.
