Hot melt adhesive 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.
Choice
Extensive area of use, fast setting time and versatility ensured 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 possibility of using glued elements in a few minutes. Before choosing a hot melt adhesive 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.
Size
Glue sticks are suitable for all materials, including fabric, paper, cardboard, metal, wood, plastic and more. The exception is PVC,plaster and concrete. With all other materials, the tool provides a strong bond. Hot melt adhesive for the gun is divided by diameter. The most common are 11 and 7 mm. There are many other sizes available. In this case, the choice of one or another depends on the existing pistol. Also, stickers can have different lengths: in the range from 4 to 20 cm.
Transparent glue
Gun hot melt adhesive, which specifications may vary, is suitable for certain materials. It comes 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 of related products. It works with any base. Therefore, this option is optimal for domestic use and creating crafts. Transparent yellow compound is used with cardboard, paper and wood.
Colored rods
The category of universal also includes options with any shades, except for black. Extensive color options allow you to choose a hot melt adhesive for a gun that matches the palette of parts. 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 toproperties. But, as a rule, the shade performs only decorative functions, and the adhesive mass is universal. Hot-melt adhesive for 11 mm gun "Zubr" of gray and black color is able to act as an insulating material and sealant. It is ideal for sealing butt joints and insulation.
Temperature
Melting point is an equally important characteristic. For some rods, it is 150 degrees. For others, a lower temperature is sufficient to operate. It should be noted that for places characterized by low heating, a less fusible adhesive 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 glue for the gun can be applied with various tools:
- Glue roller or head.
- Special machine or applicator.
- A foot pedal used for professional equipment equipment.
- Household glue gun.
Composition
Ethylene vinyl acetate compounds have become the most common. They allow you to work with a variety of substrates, including fabrics, ceramics, certain types of metals, plastics, wood, and paper. There is also a hot melt adhesive for guns, which is necessary for items that are exposed to a wide range of temperatures. The chemical formula provides cleaning of the bath, nozzle and the entire instrument system from the composition that was usedpreviously. Products based on this are more stable, due to which they have gained popularity in the electronics, packaging and automotive industries. They can be used for light metal, foil, leather, hardwood and other materials with synthetic and hard resins.
Pressure-sensitive adhesive ensures tack retention. The scope of application is extensive. It includes hard-to-glue surfaces. It is used in the field of construction, the automotive industry, as well as for work with large surfaces. Hot melt adhesive for gun (black or any other color) with medium pressure sensitivity provides a sticky flat for 5 minutes. This is the best option for joining elements that are not resistant to heat and large surfaces.
What you need to know?
There are many different characteristics. But, first of all, it is necessary to build on the proposed materials. It can be polypropylene with the addition of aluminum, spunbond, plastic, laminated surface, paper and cardboard coated with UV varnish. You also need to take into account the subsequent impact on the material. For example, transportation, contact with food and water, temperature conditions are taken into account.
To obtain a reliable bond, such characteristics as shade, setting time, structure viscosity play a special role. The mass feed rate can be different. The application method is divided into automatic and manual. At the same time, a different form of composition is suitable for each type of base: tablets, pads, blocks, pins. The rate 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
The hot melt adhesive for the gun, the photo of which is presented above, may have a different viscosity, depending on the method of distribution. Compounds with a dense structure are applied with a disk or roller method, and a nozzle or nozzle is suitable for low viscosity material. Compliance with the operating cycle of the equipment and the setting time is required. Also, if it becomes necessary to replace the base for gluing, you need to make sure that you do not need to replace the glue itself. Rods from different manufacturers may have different compositions. Therefore, they should not be mixed. Otherwise, the structure and characteristics may change.
Safety
Hot glue for a gun, whose melting point depends on the composition, belongs to the category of substances with a medium degree of danger. It has low toxicity. But inhalation of vapors can contribute to short-term depression of the central nervous system. Short-term use does not require equipping with protection tools. In this case, it is desirable to ensure ventilation of the room. It is also worth noting the defeats that the method of work can lead to. In particular, these are burns that occur when the molten composition gets on the skin.
Reviews
Akfix hot melt adhesive, according to buyers, has a thick structure that simplifies use. It reliably fastens surfaces, but over time acquires a yellowish tint. Reviews about Rexant rods are mostly positive. Their main advantage is low consumption. They also significantly speed up the process of work. Glue for the gun "Zubr", according to users, is distinguished by the presence of convenient packaging, low cost and quality of the connection.
