Our range of adhesive solutions for sandwich panels:
Sandwich panel adhesives
Paramelt provides a full range of 1K and 2K PU and water-based lay-flat laminating adhesives for sandwich panel structures of numerous core and sheet materials with variants to meet different process requirements.
1K PU adhesives
The Dynol™ range of 1K PU adhesives offers broad based solutions for diverse sheet and core materials, tailored for specific production process requirements.
2K PU adhesives
The Dynol™ range of 2K PU adhesives offers tailored products for high speed, continuous production processes and for specific substrate combinations, not suitable for 1K solutions.
Water-based adhesives
Our range of Enziflex™ and Latyl™ water-based adhesives offers a number of tailored products for the gypsum, wall covering, wall construction, textile and wood market.
Enziflex and Latyl water-based adhesives (dispersions) bonding process takes place slowly because of the water being lost, either by evaporation or absorption by the substrates. Dispersion adhesives are especially suitable for bonding high-area laminated systems made of water-permeable materials.
For dispersion adhesives the open time is determined by the temperature, the thickness of the adhesive film and the absorption properties of the substrates. The substrates are then pressed against each other.
Paramelt provides a tailored range of water-based adhesives to many areas of markets.
- Gypsum
- Wall construction
- Wood
- Textile
- Wall covering
Depending on the application and market, the following properties of the adhesive are important.
- Adhesion to the substrates
- Open time
- Drying speed
- Curing speed
- Viscosity & rheology
- Water resistance
- Corrosion properties
- Stiffness
Dynol solvent-free 2K PU adhesives require the thorough mixing with a specified type and amount of an isocyanate hardener during the sandwich panel production process. The combination of the polyol and the hardener enables the adhesive layer to build up to the final bond strength.
Because a 2K PU system provides full control of the curing process, the adhesive system is suitable for a much wider range of sheet and core materials.
Depending on the combination of polyol and hardener, it is possible to formulate defined open time and setting speeds. This allows for use on high-speed, continuous production lines. Therefore, in many cases Paramelt is formulating tailored products for a particular customer process and substrate combination.
The Dynol™ range of 2K PU adhesives consist of numerous variants for both standard and special applications, such as
- Long pot-life
- Difficult surfaces (e.g. plastics, metals and coated steel)
- Fast setting
- Fire retardant products (A2 sandwich panel)
- Customer specific product and process combinations
Depending on the type of sheet and core materials and application method, the following properties of the adhesive are important:
- Open time
- Pot-life
- Fixed or adjustable mix ratio
- Viscosity (polyol plus isocyanate)
- Press temperature
- Application method and setup
- Substrate types (core and sheet materials)
Dynol solvent-free 1K PU adhesives require sufficient moisture during the sandwich panel production process to fully cure the adhesive layer and achieve the final bond strength. This means that the core and or sheet material needs to allow for moisture absorbance or transport during the curing process.
1K PU adhesives are typically used in (semi)-discontinuous processes, where the production speed is relatively low. Moisture control at the point of lamination can help to influence curing speed. Provided that the target substrates are suitable for 1K PU, the adhesive allows for more frequent changes of laminated substrates on the same line and can bring more flexibility.
Paramelt provides a tailored range of Dynol 1K PU adhesives for different curing speeds, rheology and viscosities. For more difficult to adhere substrates such as PVC, ABS or aluminium products with increased specific adhesion are available. No matter what the specific production method (nozzle, slot-nozzle, roller or hand-applied), Paramelt is able to propose a suitable Dynol grade.
Insulation adhesive properties
Depending on the type of sheet and core materials and application method, the following properties of the adhesive are important:
- Substrate types (core and sheet materials)
- Open time
- Press time
- Press temperature
- Viscosity
- Application unit and method
- Moisture demand
Adhesives for sandwich panels
Hardly a day goes by without new roofing and insulation materials appearing on the market. Materials that architects and your clients want to combine in panels.

Having tested all sorts of possible materials over the years, Paramelt has a wealth of expertise in the field of bonding. Expertise that is constantly kept up to date and has helped to underpin the development of an extensive range of one and two-component polyurethane (PU) adhesives, often specific to an individual client and each with its own particular application characteristics.
These adhesives are used to bond covering materials such as untreated, primed, coated or painted aluminium, steel and galvanized steel, wood, plasterboard, PC, PVC, ABS to core materials, such as PUR, PIR, EPS, XPS, mineral wool (Rockwool, glass wool), polycarbonate (PC) and aluminium honeycombs.
Paramelt provides a full range of lay flat laminating adhesives for different types of core and sheet material as well as property sets of viscosity, open time and set time. Typical applications are A2 fire classified sandwich panels, caravan panels, cladding elements, insulation panels as well as prefabricated roof elements.
The construction of a core material and multiple surface layers provides a sandwich panel with strength and rigidity. A wide variety of core and face materials is used and the material choice depends on the detailed application requirements.
With the right adhesive selection, this results in high strength, light weight and cost-effective panels with excellent form stability, torsional stiffness and load bearing capacity.
