Hot-melt adhesives

kleje hot melt, are extremely popular. They are incredibly versatile and useful adhesives that are used in a variety of areas in both everyday applications and industry. It is therefore worth taking a closer look at their unique properties and the benefits they bring.

PUR adhesives – reactive polyurethane adhesives

PUR adhesives are used in a variety of industries and are characterised by a process of irreversible cross-linking of the joint on contact with moisture. Their main advantage is their high bonding capacity and speed, which translates into work efficiency. PUR adhesives also provide water resistance and resistance of the joint to external influences such as changing weather conditions or mechanical loads. PUR hotmelt adhesives are reactive adhesive systems which, after initial bonding, enter into further cross-linking with each other and the materials being bonded. This makes them ideal for bonding components with different properties and structures. Reactive polyurethane adhesives are able to provide a durable, waterproof and mechanically strong bond. For this reason, they are widely used in furniture manufacturing, industrial automotive manufacturing and also in the construction industry. These adhesives are very popular due to their versatility and reliability in creating durable bonds.

Hot melt adhesives – types and characteristics

Hot melt adhesives are a type of thermoplastic solid that can be heated to its melting point, causing it to turn into a liquid. There is no water or solvents in their composition. This is very convenient because the adhesive, when subjected to a temperature of 120 – 180°C, turns into a liquid and can be easily spread on various surfaces. As soon as it cools down, it acquires adhesive properties and shows high durability and adhesion to the substrate. The basis of hot melt adhesives is a polymer, which is EVA (check also – EVA adhesives), polyolefin or synthetic rubber (check also – synthetic rubber-based adhesives). Hot melt adhesives are widely used in a variety of fields such as industry, electronics or art, enabling unique designs to be created. Its flexibility and good adhesive properties make hot melt adhesives an extremely versatile material that has found applications in many areas of everyday life.

Advantages of hot melt adhesives

The versatility of hot melt adhesives is one of their most important features, as they can be successfully used as industrial adhesives in a variety of industries. Thanks to their ease of use, they are very popular with professionals as well as amateurs who need to bond two surfaces quickly and effectively. Their fixation is instantaneous, which significantly speeds up the production and repair process. It should also not be forgotten that hot melt adhesives are safe for the environment and health, as they do not emit harmful substances.

Hot melt adhesive – can I glue anything with it?

Hot melt adhesives are characterised by unique properties that make them indispensable in many applications. One of their key strengths is their versatility. They offer the ability to bond a wide variety of materials, including plastics, fabrics, wood, metal.

Properties of hot melt adhesives

Hot melt adhesives have many desirable properties that make them so widely used. They can be used to join different types of materials, such as wood, metal, glass or plastics. An additional advantage of hot melt adhesives is their ease of use – all that is required is to heat the adhesive sufficiently to make it sticky and ready for use. These adhesives are characterised by their high viscosity, so you can expect a durable bond. Hot melt adhesives cure very quickly, making the manufacturing or repair process fast and efficient.

Hotmelt adhesive applications

Hot melt adhesives are widely used not only in home workshops, but also in various industrial sectors. In the packaging industry, it is these adhesives that are commonly used to bond plastics and to glue cardboard and cardboard. In the crafts industry, hot melt adhesives are indispensable for a variety of assembly work. In the furniture industry, hot melt adhesives are used to bond various furniture components, such as the edges of furniture boards or plastic profiles.Another industry where hot melt adhesives are commonly used is the textile industry, where they are used to bond or laminate various materials, such as fabrics, leathers or knitted fabrics. Thanks to their advantages, hot melt adhesives play an important role in many industries, enabling materials to be joined permanently.

Hot-melt adhesives – summary

Hot melt adhesives, such as, for example, EVA hot melt adhesives, are a type of hot melt adhesive with high bond strength and resistance to a variety of factors. They are widely used in many manufacturing plants to create strong bonds. These adhesives can be applied using equipment or special guns that dissolve the adhesive at a high temperature and then apply it to the surface of the materials to be joined linearly or by spraying. These adhesives can also be heat-activated, which means that once they have cooled down, they can form a bond characterised by high adhesion with high moisture and stress resistance, but with low heat resistance.
