Hot melt glue guns are designed for use with our range of industry standard 12mm diameter hot melt adhesive glue sticks. They work by melting sticks of glue at high temperatures and as the glue cools it hardens, attaching to the surface, enabling you to firmly bond a variety of materials together. Although glue guns originally served the purpose of bonding soles to shoes, their uses have since evolved and expanded into multiple industries. Nowadays, they are considered to be standard household tools that can be used for DIY, hobby and craft projects, as well as being used in professional industries, such as spine gluing in bookbinding, woodworking, manufacturing, and packaging to name a few examples.
