Heat-activatable adhesives based on Bayer MaterialScience´s Polyurethane Dispersion range Dispercoll® U have become established worldwide in demanding industrial applications. However, ultimate performance such as Heat Resistance can only be achieved through a high molecular weight chemically crosslinked adhesive, using a conventional crosslinking isocyanate. Additionally, the use of such 2-component adhesive system requires the adhesive end user to accurately meter and mix the crosslinking isocyanate.

Over the past few years, Bayer MaterialScience has developed polyurethane dispersions with surface deactivated finely dispersed isocyanate particles, so called latent-reactive polyurethane dispersions. A very interesting aspect of this technology is the possibility to pre-coat substrate surfaces with a storage stable reactive adhesive film or to prepare separate storage stable reactive adhesive films. The crosslinking of the polyurethane polymer is then initiated by heat activation. During this WebSeminar, you will be introduced to the technology of latent-reactive polyurethane dispersions.

Jeff Dormish and Jörg Büchner will discuss the use of latent-reactive systems for pre-coatings and films in adhesive applications.
