Maximizing Moisture Resistance in Structural Epoxy & Polyurethane Adhesives

If you are not careful while selecting ingredients (polyols, base polymers, curing agents...) to formulate your structural adhesive, the bonded joint may not hold up in extreme environment conditions (marine, windmills...). This occurs mainly due to the negative impact of moisture.

Tackling this issue using trial-and-error method or choosing an outdated solution will not help! Join this course to:

1. Understand how moisture negatively impacts the bulk properties of structural adhesives, interfaces, & substrates.


2. Maximize moisture resistance with the right selection of ingredients (polyols, base polymers, curing agents...) as per applications (transportation, wind turbine blades, marine, civil engineering...)


3. Ensure long-term adhesive strength without affecting other desirable application & service-life properties using expert tips.


4. Learn about chemical testing environment standards with practical examples.


5. Get advice on your own technical challenges by interacting live with our experienced expert Edward Petrie.

Epoxy & Polyurethane Adhesive Formulators and End-Users who are looking to enhance the service life of their structural adhesives while maximizing moisture resistance must opt for this course.
