Some furniture surfaces are three-dimensional – typically specially formed or milled MDF panels – either for structural or design-related reasons. To achieve an appealing look, feel, and functional performance, these surfaces are laminated using 3D processes such as membrane or vacuum pressing.
Low-viscosity, single- or two-component PUR dispersions are generally used for this type of lamination.
Typical applications include:
- Fronts
- Shelf tops for sideboards and display cabinets
- Wardrobe doors
- Door panels
Common material combinations typically include:
- PVC films and MDF
- PP films and MDF
- ABS films and MDF
- Real wood veneers and MDF
Narrow radii and sharp contours present particular challenges in 3D lamination. Achieving high-quality results requires both the right adhesive and expert application know-how.
PUR dispersions are the preferred choice, as they are suitable for bonding standard films as well as high-gloss décors. Even very thin films that are sensitive to elevated temperatures can be laminated successfully with the appropriate dispersion.
The PUR dispersion is applied to the substrate either manually using a spray gun or automatically via spray nozzles, after which the decorative material is pressed on using a vacuum or membrane press. The pressure and heat inside the press reactivate the adhesive, allowing the film to conform precisely to the contours of the substrate.
PVAc dispersions (also known as white glues) can be used for laminating real wood veneers and offer a cost-effective alternative to PUR dispersions for bonding various types of veneers. Before bonding in a membrane press, the veneers are moistened to prevent cracking or tearing during pressing. In Kleiberit’s experience, PUR dispersions remain the best choice when very high resistance to temperature and moisture is required – for example, in bathroom or kitchen furniture.
