Why you should use MITOPUR adhesives for your sandwich panel project

Sandwich panels are versatile and efficient products that can be used for various applications, such as building, transportation, and refrigeration. Sandwich panels consist of two outer layers of metal, composite, or wood, and an inner core of insulating material, such as foam or honeycomb. To create a strong and durable sandwich panel, you need a high-quality sandwich panel adhesive that can bond the layers together and withstand different environmental conditions. In this article, we will introduce you to MITOPUR adhesives, a range of one- or two-component polyurethane adhesives that are specially designed for sandwich panel production. We will explain the benefits and features of MITOPUR adhesives, and how they can help you achieve your sandwich panel project goals.

MITOPUR adhesives can bond to various substrates and core materials, such as metals, wood, plastics, ceramics, and insulation materials.

The benefits of MITOPUR adhesives

MITOPUR adhesives are one or two-component polyurethane adhesives that are manufactured by Mitol, a leading European producer of adhesives with over 75 years of experience1. MITOPUR sandwich panel adhesives offer several benefits for sandwich panel production, such as:

• Excellent adhesion: MITOPUR adhesives can bond to various substrates and core materials, such as metals, wood, plastics, ceramics, and insulation materials. They can also fill the gaps and reduce the consumption of glue.
• Water and temperature resistance: MITOPUR adhesives are water-resistant according to EN 204 D4 which means they can withstand exposure to water and humidity. They are also temperature-resistant from -40°C to +80°C, which means they can cope with high and low temperature cycles.
• Strong and elastic joint: MITOPUR adhesives have high final strength and retain elasticity even at low temperatures. They can provide good thermal insulation and structural integrity for the sandwich panel.
• Solvent-free and odour-free: MITOPUR adhesives do not contain any solvents or emit any unpleasant odours. They are environmentally friendly and safe to use.
• MITOPUR adhesives can also have fire-retardent properties.

The features of MITOPUR adhesives

MITOPUR adhesives are available in different types and forms, depending on your application method and production speed. You can choose from:

• One-component polyurethane adhesives (1C): These are reactive systems that cure by a chemical reaction between glue and moisture or water. They are suitable for manual spreading with roller or notched trowel for gluing small or large dimensions of sandwich panels. Some examples of 1C MITOPUR adhesives are MITOPUR E19 and MITOPUR E55.
• Two-component polyurethane adhesives (2C): These are reactive systems that cure by a chemical reaction between two components. They are suitable for machine mixing and spreading in high production serial gluing. Many types in range by name MITOPUR.

MITOPUR adhesives have different viscosity and pot life, which means you can adjust the amount and the time of application according to your needs. They also have different open time and cure time, which means you can control the speed and the quantity of the production process.

How to use MITOPUR adhesives

To use MITOPUR adhesives for your sandwich panel project, you need to follow some simple steps:

• Prepare the surfaces: make sure the surfaces of the substrates and core materials are clean, dry, and free of dust, grease, or oil. If necessary, sand or degrease the surfaces to improve the adhesion.
• Apply the adhesive: depending on the type of adhesive you choose, apply it manually or automatically on one surface. Use a roller or a notched trowel or a machine. Follow the instructions of the product TDS (Technical data sheet) for the correct amount and method of application.
• Press the surfaces together: align the surfaces carefully and press them together firmly. Avoid any movement or displacement during the curing process.
• Wait for the adhesive to cure: depending on the type of adhesive you choose, wait for the appropriate time for the adhesive to cure completely. Follow the instructions for the correct curing time and temperature.
