Hot Glue Hot Melt


Experts advise people to choose the glue they use very carefully. It is important to know what different types of glue are used to glue different materials. If intending to glue unusual combinations of materials, such as wallpaper on metal surfaces or leather on pottery, then universal glue or specialist glue intended for particular materials can be used, but glue containing solvents should be avoided.

An example of solvent-free glue is thermoplastic or hot glue. They have become more and more popular recently not only for use in construction but also for domestic use. They are easy to use; in addition, this type of glue is both cheap and highly effective. It adheres instantly and can be used with almost any kind of material. It is an adhesive substance which may melts when heated, and hardens when it cools down. Glue is usually made of various polymeric materials, i. e. one base material and various impurities which keep the base material in a stable condition at room temperature. The impurities enable the temperature at which it melts and crystallises to be changed. Most commonly, a mixture of polypropylene and various resins is used in glue production. In other words, it is a plastic material that remains solid at room temperature. It melts if heated, but unlike other types of glue, it hardens incredibly quickly. It is water-resistant and non-toxic.

This type of glue can fill spaces, does not shrink and is resistant to mechanical stimuli, so it is convenient to use for gluing non-smooth materials. In domestic situations, hot glue guns are used containing a glue stick and the heating element. Glue in this kind of gun is very hot, and so users should be careful. Hot glue is sticky, but it can harden within a minute or even within a few seconds. Glues that melt at higher temperatures are easily distributed on the surface, but are not so durable, and the glue hat melts at lower temperatures is more difficult to use but they are firm and of high quality.

Hot glue has a number of advantages: any domestic works which include gluing can be carried out in a cleaner and faster manner; the glue may be removed and the place of the item may be changed at any time; in addition, they are convenient to use in situations when an item needs to be glued, and use of another type of glue is not possible because there is not time to wait for 12 hours while it dries and there is no space for mistakes, so the process needs to be planned in advance. Such guns are perfect for making a variety of types of handicrafts: for example, for collages made from natural and artificial materials. They are perfect for gluing puppets, souvenirs, toys, architectural layouts and other things. This glue perfectly glues fabrics, wood, ceramics, plastics and so on. The glue gun can serve you for several years, but it is important to prevent it from overheating and it should not be plugged into a power outlet for more than 15-20 minutes at a time. If the body of the gun seems hot, it should be turned off, but the glue can still be used for some time after this. When the gun gets cooler, it can be turned on again.

This glue is a good choice if you have to glue plastic often. Plastics, including Teflon, nylon, polypropylene and so on are famously are almost impossible to glue: plastic surfaces are too smooth and slippery, and most glue does not stick, but the glue gun copes with this task perfectly. In addition, it can not only glue two surfaces together, but can also fill in gaps, if a harder material melting at lower temperatures is used. It has been claimed that this glue can even be used for metals. It must be borne in mind that the properties of different glue vary, but the universal glue can be used for various materials, so it is not surprising that this glue is so popular.
