PUR glue is a reactive polyurethane hot melt. It is applied molten and gives fast initial tack on cooling, then reacts with moisture to become a thermoset that cannot be remelted.

Benefits

High heat and water resistance, very thin bond lines ("zero joint" edges), adhesion to wood, metal, PVC, ABS, composites and textiles, and low coat weights.

Uses

Edge banding, profile wrapping, flat lamination, panels and doors, automotive trim, textile lamination and filters.

Tips

Protect the melt from moisture (closed melters, slot nozzles), keep to the recommended temperature, clean equipment at stoppages and allow several days for full cure.
