What is a PUR hot melt gun?

A PUR hot melt gun is a handheld tool that applies a specialized type of hot melt adhesive, known as polyurethane reactive (PUR) hot melt, to a variety of surfaces. PUR hot melt guns are often used in woodworking, construction, and other industries that require strong, long-lasting bonds.

How does a PUR hot melt gun work?

Some PUR hot melt guns like the Infinity Bond Flex 50 can heat up 50-gram PUR cartridges and dispense the molten adhesive through a nozzle onto the surface being bonded. Others are connected to a tank and are only used to dispense PUR. Portable PUR hot melt guns typically have an adjustable temperature feature, while bulk PUR guns have flow settings to accommodate different application needs.
