Wednesday Apr 26, 2017

Better select wax for your hot melt adhesives to meet faster your end requirements (fast setting/ long open time / good hot tack...).

Johan Goris will help you understand:

  • The link between waxes characteristics (drop melting point, congealing point…) & hot melt properties
  • How to better balance open time vs. setting speed without wasting time on trial & error

Why should you attend?

Knowing how waxes influence hot melt open time, setting speed, hot tack… is the key, if you’re trying to efficiently select waxes to meet specific needs for your hot melts. Avoid wasting time on trial and error by understanding how you can better balance between open time versus setting speed. Join this course and:

  1. Understand the dependence between your wax characteristics & your hot melts performance (open time, setting, hot tack...)
  2. Select the right wax among the many types available (PE, FT PP...) with better characterization (melting point, crystallization point, molecular weight distribution…)
  3. Understand why it is not working when you are facing a failure by reviewing formulation factors influencing performance
