The Infinity Bond PUR WW30 is a woodworking polyurethane PUR hot melt with a 30 second open time. It dispenses from an easy-to-use cordless cartridge glue gun and bonds exceptionally well to wood, laminates, light plastics and metals. The Infinity PUR WW30 offers a significantly stronger bond than traditional glue sticks or bulk hot melt. It also holds up better to difficult conditions including exterior applications. Infinity PUR WW30 offers a good initial tack and a bond that will continue to strengthen as it reacts with moisture in the air.
