Glue guns can be bought in low temperature and high temperature hot-melt versions. Low temperature units heat up to about 120º C and are more suitable where a high temperature is not wanted. High-temperature guns} heat up to around 195°C and result in a stronger bond. Also available are dual glue guns which feature a switch so that both low and high temperatures can be utilised for different applications.

For industrial applications, there are a broad range of heavy duty industrial glue guns available which are designed to optimise production efficiency. These range from high output compressed air industrial glue guns to multi temperature guns.

Glue sticks are on the market in various sizes for different types and sizes of glue guns. The commonest size has a diameter of 11mm. Glue sticks are also available in various lengths, from about 10cm upwards. However, most glue guns will accommodate glue sticks of any length. Hot melt and low temperature glue sticks are available for the different types of glue gun. Hot melt adhesives do not contain any solvents or water. They bond when they fall in temperature and this means that they can set quickly.

For industrial purposes, different types of glue sticks are available for specialist uses. The commonest diameters are 12 and 43mm. For domestic use, there are only a few types of glue sticks that are available. Glue sticks have different open times, which is the time taken to form a bond. This varies from a couple of seconds to several minutes.

Glue guns need to be switched on several minutes before being used so that the heating element and glue stick can warm up. As the glue stick gets hot it melts and then it can be used to bond various materials together. Care should be taken when using hot glue guns as hot glue can be dangerous.
