A Guide To Glue Guns and Adhesives
Glue guns can be purchased 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 undesirable. High-temperature glue guns} heat up to approximately 195°C and result in a stronger bond. Also on the market are dual glue guns which feature a switch so that both low and high temperatures can be utilised for different purposes.
For industrial purposes, there are a wide range of heavy duty glue guns available which are designed to optimise production efficiency. These units range from high output pneumatic industrial glue guns to variable temperature guns.
Glue sticks are available in several different diameters for different varieties 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, the majority of 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 set when they decrease in temperature and this means that they can set quickly.
For industrial applications, different types of glue sticks are available for specialist uses. The commonest diameters are 12 and 43mm. For home 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 few seconds to several minutes.
Glue guns should be switched on a few minutes before being used so that the heating element and adhesive can warm up. As the glue stick increases in temperature 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.
