What is PUR Hot Melt?
Polyurethane hot melts offer a quick adhesion because of the cooling down from high application temperature of approx. 140°C to room temperature. An additional chemical reaction with humidity provides a very strong bond to various substrates.

What are thermoplastic hot melt adhesives?
Thermoplastic hot–melt adhesives will melt again when it’s heated. Unlike polyurethane hotmelts that will go into a curing process after application.
