polyurethane adhesives

Large area polyurethane adhesives are specialised products that are used in a wide variety of industries due to their unique properties. Their description and applications are outlined below.
Description of Polyurethane Adhesives
Polyurethane adhesives, also known as urethane adhesives, are available in one and two component forms. They are characterised by their high bonding strength to a wide range of materials such as

    Wood
    Plastics (including PVC, polystyrene)
    Metals (steel, aluminium, copper)
    ceramics
    Insulating foams (polystyrene, polyurethane)

Due to their molecular structure, these adhesives form strong bonds, making them ideal for applications where high strength and flexibility are required.
Key properties

    Flexibility: Able to withstand dynamic loads and temperature changes.
    Chemical resistance: These adhesives are resistant to water, oil and chemicals, making them ideal for applications in harsh environments.
    Fast cure: Once applied, the adhesive quickly reaches full strength, speeding up the production process.

Typical applications
Large area polyurethane adhesives are used in a wide range of applications:

    Construction: Used to bond wood components and building materials, providing resistance to moisture and temperature changes.
    Furniture industry: Ideal for bonding various types of wood and wood-based composites.
    Footwear industry: Used to bond leather to synthetic materials, providing flexible and durable bonds.
    Manufacture of sandwich components: Used in the construction of isothermal walls and containers.
    Industrial applications: Used in the manufacture of components requiring high strength and chemical resistance.

Polyurethane adhesives are valued for their versatility and ability to effectively bond a variety of materials in demanding conditions.
