WB Adhesives: Predictive Methods for Faster Developments

This is a Past Course

Recorded on Mar 5, 2014

Adjust faster adhesion, Tg, wet tack, setting speed… by knowing what & by how much you should change your water-based adhesive formulation BEFORE trying.

David Horwat will share his hands-on experience using particle distribution, Tg & molecular weight… to reach desired performance in a timely manner.

Why should you view this course?

Waterborne adhesive formulators experience increased pressure to tailor their products faster & at lower cost in order to meet their customers very specific end-use requirements. This productivity gain cannot be achieved without reviewing development process & thinking smartly at future steps... To this extend, computerized formulation is the way to go!

  1. Make better decisions (right the first time) for your WB adhesive developments with a smarter use of physical variables
  2. Set up smaller series of experiments to get the needed results (predict Tg, work at constant Tg or viscosity...)
  3. Implement straight away the good practices discussed - the only thing you need is an Excel spreadsheet!
WB Adhesives: Predictive Methods for Faster Developments

Who should view this course?

Intermediate to skilled WB adhesive formulators
Especially those involved in packaging/ laminating applications.

Course Outline

The following sections will be covered during this session:

  1. The productivity advantages of predicting formulation results

  2. Key Structure Property Relationships for polymer raw materials

  3. Modeling the Tg of a formulation

  4. Experimental design using predicted Tg results

  5. Key Structure property relations for wet rheology

  6. Historical Models

  7. The two regions of viscosity / solids prediction

  8. The 3 key variables:
          • Aqueous Viscosity
          • Critical Packing Factor
          • Mean Particle Size

  9. Plasticizer response as a key parameter

  10. Other properties as linked to Viscosity

Excellent course! The concept of modifying Tg without changing viscosity is of great use for DOE's and deeper understanding of formulations

Minedys M. , from Hewlett-Packard

Very good! It gives an interesting and consistant way to look at current and new materials in terms of drying and hopefully on some physical properties.

Jean-Bernard C. , from PROMA ADHESIVES

Useful information on the design of formulations have been shown.

Dolores K. , from MITOL

As water based technology is relatively new to me, it gave me good tools to characterize some properties
