Reactive Polyurethane Hot-Melt Adhesives Solvent-Free

Reactive Polyurethane Hot-Melt Adhesives (Solvent-Free) 

During the application, the so-called skinning time has to be observed, that is, the time in which the contact with the humidity of the air already leads to a curing reaction on the surface. This skin prevents a sufficient wettability of the second adherend. 

The outstanding property of such PUR adhesive layers is their high elasticity or flexibility over a wide temperature range (approximately -40 to 80 °C). This thermomechanic behavior is the precondition for the application in car industry.
