Hot Melt Bulk - PUR

The latest hot melt adhesive advance is the PUR adhesive, which is a 100 percent solid, one-component urethane prepolymer that "behaves like a standard hot melt until it reacts with moisture to crosslink or chain extend, forming a new polyurethane polymer." By curing the polymer in this way, PURs have performance characteristics that are more enhanced than those of standard hot melts. It achieves its ultimate strength over the next few days by reacting with moisture in the air and substrates to form a significantly stronger bond than a conventional hot melt.
