Hot-melt pressure-sensitive adhesives

Hot-melt pressure-sensitive adhesives are adhesives on the basis of thermoplastic rubber.

These are characterised by the fact that they do not set completely, but remain permanently tacky.  For this reason, the designation “PSA – Pressure Sensitive Adhesive” was created for this group of adhesives.

There is a very wide range of formulation options that can be used to adjust the final properties of hot-melt pressure-sensitive adhesives. Such adjustable properties include surface tack, cohesion and adhesion etc.

The contact pressure has a major influence on the resulting adhesive strength, in order to achieve sufficient wetting between the hot-melt adhesive and the substrate.  

In many applications, bonding takes place in the cold state, for example, when closing packages or shipping bags (self-adhesive closures).

On the other hand, there are industrial inline gluing processes whereby the substrates are joined with the still warm adhesive. One example of this is insulation board lamination in insulating materials.  

In addition, a distinction is made in the pressure-sensitive hot-melt adhesives between permanently adhesive and removable/repositionable types; these can often be found in magazines with free samples.
