Choosing Between One and Two-Component Adhesives: Which Is Right for Your Project?

When it comes to constructing durable and efficient structures, the choice of adhesives plays a pivotal role. Sandwich panel adhesives have emerged as game-changers in various industries, offering robust options for multipurpose sandwich panels. In this article, we'll delve into the world of these adhesives, exploring their types and characteristics. They can be broadly categorized into two primary types.

MITOPUR adhesives are versatile, adhering to a wide range of substrates and core materials.

One-Component Polyurethane Adhesives

  • Composition: These adhesives consist of a single component, pre-formulated and ready to use without the need for mixing.
  • Application: Ideal for applications where efficiency and convenience are essential, often used in high-production settings.
  • Advantages: Known for their fast curing properties, making them suitable for machine mixing and spreading. Available in various viscosities to meet different bonding requirements. Efficient application with spray method, simple manual spreading using a roller or notched trowel. Effective infiltration into insulating material because of its low viscosity and foaming characteristics.
  • Use Cases: Commonly used in industries like caravaning, air- conditioning, and building elements for bonding various plates onto isolating materials. Their versatility makes them suitable for both large-scale production and manual application.

    Two-Component Polyurethane Adhesives

    • Composition: These adhesives consist of two separate components, including a polyol and a hardener, requiring mixing before application.
    • Application: Favored for applications on thin plates and decorative panels, where foaming of the one-component polyurethane adhesive due to the transfer of bubbles to the surface is not desired.
    • Advantages: Offer flexibility in bonding larger surfaces or higher capacity due to their possibility of adjusting open time and pressing time. They can be adjusted for pot life by adding a catalyst, providing an optimum production process. Solvent and odor-free adhesives ensure a pleasant working environment. High production capacity due to short pressing time. Excellent processing with spray application or manual spreading with a roller or notched trowel. Suitable for assembling applications on vertical and ceiling surfaces.
    • Use Cases: Often employed in the construction of sandwich panels used in building constructions like aluminum doors, metal roofing, mobile homes, containers, clean rooms, and other applications where strong, temperature and water-resistant joints are required.

    MITOPUR adhesives are water-resistant, tolerate a wide temperature range, provide thermal insulation, and are environmentally friendly.

    Advantages of MITOPUR Adhesives

    As a trusted solution provider, MITOL offers a diverse range of sandwich panel adhesives known as MITOPUR. These adhesives are available in one or two-component formulations, ensuring flexibility in bonding processes. MITOPUR adhesives cater to a wide spectrum of industries, including automotive, air- conditioning, building elements, and shipbuilding.

    MITOPUR adhesives are capable of adhering to a wide range of substrates and core materials, such as metals, wood, plastics, ceramics, and insulation materials such as mineral wool, EPS, XPS, polyurethane foams, and metal honeycomb. Additionally, they can fill gaps and reduce glue consumption. These adhesives are water-resistant according to EN 204 D4 and can tolerate temperatures ranging from -40°C to +120°C. They have a high final strength and remain elastic even at low temperatures, while also providing thermal insulation and structural integrity to sandwich panels.

    To wrap up

    MITOPUR adhesives by MITOL are versatile one and two-component polyurethane adhesives used in various applications. One-component options like MITOPUR E20 or E45 are suitable for wood, metals, plastics, and more. Meanwhile, two-component adhesives like A1+B7 or A2+B7 are ideal for surface bonding of metals, wood, plastics, ceramics, and insulation materials. These adhesives offer convenience, flexibility, and environmental friendliness, making them suitable for various projects.
