Hot glue for a gun is a substance that acquires a viscous structure when heated to a certain temperature. It gets a solid state after complete cooling.
The choice
A wide area of use, fast time for fastening and versatility have provided the popularity of this tool. The form of its release can be any - pillows, blocks, granules and rods, which have become most widespread and have a variety of diameters and sizes. The main advantage is the ability to use glued elements in a few minutes. Before choosing a hot glue for a gun, the characteristics of which depend on the shape, you need to purchase the tool with which it is used. Of course, working with this tool is possible without a special gun. For example, by heating with a candle or a soldering iron. But this is at least inconvenient.
The size
Glue sticks are suitable for any materials, including fabric, paper, cardboard, metal, wood, plastic and others. The exceptions are PVC, plaster and concrete. With all other materials, the tool provides a strong bond. Hot glue for the gun is divided by diameter. The most common are 11 and 7 mm. There are many other sizes. In this case, the choice of one or another depends on the available gun. Stickers can also have different lengths: in the range from 4 to 20 cm.
Transparent glue
Hot melt glue for the gun, the characteristics of which may be different, is suitable for certain materials. It is represented in many shades. All types of this substance differ in properties and component composition. The most widely used white transparent sticker due to its versatility. It can be found in any store related products. It is suitable for working with any foundation. Therefore, this option is optimal in domestic use and the creation of crafts. Transparent yellow composition used with cardboard, paper and wood.
Colored rods
Versions with any shades, with the exception of black, also belong to the category of universal. An extensive color design allows you to choose a hot glue for the gun, which corresponds to the parts palette. For example, when working with a red vase, in order to get inconspicuous joints, you need to take a scarlet cartridge. Opaque white stickers are suitable for gluing a white base and elements stylized as metal or glass. When purchasing, pay attention to the properties. But, as a rule, the shade performs only decorative functions, and the adhesive mass is universal. Hot-melt adhesive for the 11 mm Zubr gun in gray and black is able to act as an insulating material and sealant. It is ideal for sealing joints and insulation.
Temperature
Melting point is an equally important characteristic. In some rods, it is 150 degrees. Another is enough to operate at a lower temperature. It is worth noting that for places characterized by a slight heating, less fusible glue should be selected. When choosing, it is necessary to take into account the characteristics of the thermal gun and the materials used for work. Hot melt adhesive for the gun can be applied with various tools:
- Glue roller or head.
- Special machine or applicator.
- The foot pedal used to equip professional devices.
- Glue household gun.
Composition
Ethylene vinyl acetate compounds are most prevalent. They allow you to work with various bases, including fabrics, ceramics, a certain type of metal, plastic, wood and paper. There is also a polyofinol hot melt adhesive for the gun, the use of which is necessary for objects exposed to a wide range of temperatures. The chemical formula provides the cleaning of the bath, nozzle and the entire instrument system from the composition that was used previously. Funds on this basis are more stable, which is why they have become widespread in the electronic, packaging and automotive industries. They can be used for light metal, foil, leather, hardwood and other materials characterized by the presence of synthetic and hard resins.
The adhesive, which belongs to the category of pressure-sensitive products, ensures the stickiness. The scope is vast. It includes hard-to-stick planes. It is used in the field of construction, the automotive industry, as well as for work with large surfaces. Hot-melt adhesive for the gun (black or any other color) with medium pressure sensitivity ensures that the sticky plane remains for 5 minutes. This is the best option for connecting elements that are not resistant to heat and large surfaces.
What do you need to know?
There are many different characteristics. But, first of all, it is necessary to build on the proposed materials. This can be polypropylene with the addition of aluminum, spunbond, plastic, laminated surface, paper and cardboard coated with ultraviolet varnish. It is also necessary to take into account the subsequent impact on the material. For example, transportation, contact with food and water, and temperature conditions are taken into account.
To obtain reliable bonding, a special role is played by such characteristics as shade, pour time, and structure viscosity. The feed rate may vary. The application procedure is divided into automatic and manual. Moreover, for each type of base a different form of composition is suitable: tablets, pads, blocks, pins. The speed of preparation of the mass and its fluidity directly depend on the rate of melting of the rod. As a rule, the tool is designed to work with a certain type of composition. Some professional options have a temperature change function.
Application features
Hot melt adhesive for the gun, the photo of which is presented above, can have a different viscosity, depending on the distribution method. Compositions with a dense structure are applied by the disk or roller method, and the nozzle or nozzle is suitable for low-viscosity material. Compliance with the duty cycle of the equipment and setting time is required. Also, when it becomes necessary to replace the base for gluing, you need to make sure that the glue itself does not need to be replaced. Rods from different manufacturers may have different component composition. Therefore, they should not be mixed. Otherwise, a change in structure and characteristics is possible.
Safety precautions
Hot melt adhesive for the gun, the melting point of which depends on the composition, is classified as a medium hazard substance. It is characterized by low toxicity. But vapor in the airways can contribute to short-term inhibition of the central nervous system. Short-term use does not require equipping with protection tools. In this case, it is desirable to provide ventilation of the room. It is also worth noting the defeat that can lead to a working technique. In particular, these are burns that occur when a molten composition enters the skin.
Reviews
Akfix hot melt, according to customers, has a thick structure that simplifies use. It reliably fastens surfaces, but eventually acquires a yellowish tint. Rexant rods reviews are mostly positive. Their main advantage is low consumption. They also significantly accelerate the process of work. Adhesive for the gun "Bison", as noted by users, is characterized by the presence of convenient packaging, low cost and quality of the connection.
