Adhesives for modular kitchen and bathroom furniture
Adhesives are used in a variety of ways to manufacture case furniture. This is the case, for example, for surface or profile laminating processes, edge bonding or carcass gluing. Especially for bathroom or kitchen furniture, the use of the right adhesive is crucial. This is the only way to produce furniture that can withstand external influences for years. These are primarily heat and moisture or steam. Furthermore, the right adhesive is crucial for smooth, economically efficient production. Polyurethane-based adhesives offer by far the best performance. Of course, our reactive PUR hotmelt adhesives are also available in micro-emission quality.

2D surface lamination
Adhesives for laminating furniture fronts
Modular bathroom and kitchen furniture is often made of wood-based materials such as MDF or chipboard, which is then coated with decor materials to protect the substrate and to make the product more visually appealing. Popular decors are: paper, hard-wearing laminates (CPL, HPL), PVC, ABS, PP, PMMA and PET films, and real wood veneers. There is a huge choice of decor materials available, giving kitchen designers endless design options. Elements that are commonly laminated are:
- fronts
- sides
- rear panels
- shelves
Supermatt and high-gloss decors are currently en vogue. The surfaces must be mirror-smooth, also across bonded edges and especially on thin decors, as even the smallest irregularities will impact the apearance. The surfaces must also be very resistant to moisture, heat and steam over the long term.
Our product range includes a series of adhesives specifically for high-gloss surfaces, as well as for other decors. We also offer tried-and-tested inline solutions for effective surface bonding and edge banding in a single run (e.g. the CompleteLine process).
Our engineers have decades of experience in bonding a wide variety of material combinations. They have extensive knowledge of the standard machines and application methods, and are committed to developing customized bonding solutions for and with our customers.

3D surface lamination
Kitchen and bathroom furniture sometimes has a 3D surface for aesthetic or design reasons. MDF boards are commonly used for shaker panelling, for instance. Durability is a key aspect for kitchen furniture. In kitchens as in bathrooms, the furniture is constantly exposed to heat, moisture and steam. It is therefore essential that the adhesive used to glue the decor and the substrate has the same long-lasting properties as the other materials. 3D coating is most commonly used for kitchen and bathroom fronts.
Typical material combinations are:
- PVC films and MDF
- PP films and MDF
- PET films and MDF
- ABS films and MDF
- real wood veneers and MDF
Laminating is usually done with low viscosity, polyurethane-based 1C or 2C dispersions, using membrane or vacuum presses. With the right know-how and the right product – e.g. a PUR dispersion – even high-gloss decors and very sensitive films that do not tolerate high joining temperatures can be perfectly bonded.
Polyurethane dispersions are sprayed to the wood-based boards using a manual gun, a spraying machine, or robot technology. The adhesive is then dried, and the bonding should take place within the next 24 hours. To this purpose, the product is placed in either a vacuum or membrane press, where the decor film is applied. Temperature and pressure reactivate the adhesive, allowing the decor film to adapt to the 3D contours of the product.
PVAc dispersions (white glues) can also be used for gluing veneers. Before being pressed, the veneers are slightly moistened on the surfaces that will later be visible, to prevent any cracks or tears occurring during the pressing process. Both materials are then pressed in a membrane press.

Edge banding for kitchen and bathroom furniture
Edge banding gives the finishing touch to coated boards. The visible narrow surfaces are coated with decorative plastic, wood or metal edges, so that the final product looks as if it was cast in a single mould. The joints between the materials are particularly fragile, but must be made as invisible and physically tight as possible. Kitchen and bathroom furniture, in particular, is often exposed to water, steam and heat. If a badly made edge joint comes into contact with these elements, it will begin to swell and, sooner or later, ruin the whole piece of furniture.
There is a huge variety of edge banding materials on the market; plastic, metal or wood are usually used. Edge banding is used for:
- fronts
- side panels
- and occasionally rear panels
The surfaces themselves are generally already laminated before edge banding is done. Typical material combinations for edge banding are:
- MDF boards with ABS edges
- chipboards with ABS edges
- sandwich panels with ABS edges
- sandwich panels with aluminium edges
- and many more.
Nowadays, zero bond lines are the standard in high quality furniture. They stand for the highest level of workmanship and offer the best protection against moisture and other elements.
Reactive PUR adhesives are the products of choice for realizing sophisticated edge banding in kitchen and bathroom furniture. With these adhesive systems, chemical cross-linking occurs after physical curing, resulting in very high temperature resistance (-30°C to +150°C) and moisture resistance. This gives reactive PUR adhesives clear benefits over EVA or polyolefin-based adhesives. KLEIBERIT PUR hotmelts are suitable for almost all edge banding purposes.
Do you need advice on which adhesive to use or how to optimize your processes? Our engineers have extensive knowledge of standard edge banding machines. Drawing on 70 years of experience in adhesives and coating machines and methods, we have the expertise to improve your specific edge banding processes. To the products & direct contact links.

Gluing dowels and furniture bodies in kitchens and bathrooms
Dowels are used to join laminated and edge-banded furniture elements, usually for corner joints, and they are often glued in. In mass production, they may be inserted with the aid of dowel insertion machines and using a special dowel glue. Either a very high viscosity or a low viscosity thixotropic dowel glue is used, depending on the intended use of the furniture and the specifics of the production process. Dowel glues are special PVAc-based dispersion adhesives that prevent the application nozzles becoming encrusted.
