Purchasing Glue Guns and Adhesives
February 20, 2012
Glue guns can be purchased in low temperature and high temperature hot-melt versions. Low temperature glue guns heat up to about 120º C and are more suitable where a high temperature is not wanted. High-temperature glue guns} heat up to around 195°C and produce a stronger bond. Also on the market are dual glue guns which feature a switch so that both low and high temperatures can be used for different purposes.
For industrial applications, there are a good range of heavy duty industrial glue guns available which are designed and constructed to optimise production efficiency. These units range from high output compressed air glue guns to adjustable temperature guns.
Glue sticks are on the market in various sizes 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 bond when they drop in temperature and this means that they can set quickly.
For industrial needs, different types of glue sticks are available for specialist uses. The most common 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 duration needed to form a bond. This varies from a few seconds to several minutes.
Glue guns need to be turned on several 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 operating hot glue guns as hot glue can be dangerous.
