Structural Epoxy Toughening: Practical Formulation Strategies

This is a Past Course

Recorded on Sep 18, 2014

Improve the toughness of your structural epoxy adhesives while keeping environmental & temperature resistance in target by reviewing the various formulation strategies.

John Bishopp (>40 year-exp.) will share his hands-on view on the benefits & drawbacks of CTBN, nanosystems, RLP/PUR blends... in regards to your toughening objectives.

Why should you view this course?

Toughening of structural epoxy adhesives is still one of the major requirements of the end-user design engineers. There is almost too much literature on the subject and a guided tour is essential to help rationalize development projects.

By attending this online course:


  1. Don't get lost in the huge amount of literature with a guided tour from a hands-on expert
  2. Identify key optimization factors (particle size, second phase Tg...) for faster achievement of your toughness targets
  3. Get practical advices on how to efficiently implement toughening strategies in your formulations by interacting with John Bishopp
Structural epoxy

Who should view this course?

Formulating chemists working in the field & to a certain degree, structural design engineers.

Course Outline

The following sections will be covered during this session:

  1. Definition of toughening
  2. Difference between flexibilising and toughening
  3. Mechanisms of toughening
  4. Detailed chemistry of the toughening polymers/telomers
  5. Reaction schematics for adduct formation
  6. Introduction to specific PUR/CTBN toughening
  7. Relatively novel low MW epoxies which aid in toughening
  8. High temperature toughening
  9. A brief introduction to nano-toughening

Excellent course! Pleased to find so much information on topic, delivered with context. Also very convenient.

Evan D. , from Willamette Valley Company

Very helpful to understand how to toughen structural adhesive!

Hong X. , from Cardolite Corporation

Perfectly what I wanted to know, VERY fast technical pace, but this is what I am looking for - lots of content!!

Wolfgang K. , from Wacker Chemie AG

Mr. Bishopp obviously knew his material well and I liked the amount of chemical detail.

Brian S. , from Ashland Inc.

Excellent! Many toughening approaches were discussed.

Andrew R. , from ITW Red Head

The structures and recommendations of specific products is good to help us have a starting point for the concepts explained in the presentation.
