One and two-component Polyurethane Adhesives are widely used to manufacture sandwich panels. Their properties carry numerous advantages that make them suitable for this type of material. These include:
High mechanical strength, makes it possible to bond various materials, including steel, aluminium, wood, composites, plastics, etc., used in sandwich panel construction. At the same time, it allows for durable and stable bonds between the different layers, which is extremely important in producing this type of panel, due to their high mechanical loads and exposure to the weather.
High flexibility, which allows compensation for movements and vibrations that occur in sandwich panels as a result of temperature changes or mechanical loads. At the same time, it ensures that the panels are resistant to damage caused by movements of the structure (e.g., in the case of panels used in transport structures).
High adhesion to a wide variety of materials, including metal, wood, plastics, etc., results in a strong and durable bond between the different layers of the panel. This results in a high-quality product with a stable structure. Resistance to atmospheric factors such as humidity, UV radiation, and temperature changes, so that the panels produced can be used outdoors, in transport structures, or in other applications where high material durability is required. Ease of processing, which significantly improves the panel production process. Adhesives can be applied using various techniques, including spraying, brushing, or in special machines.
