Unicol’s quality water based adhesives

3D membranes bond better with their substrates with Unicol adhesives.

3D membrane and vacuum presses are used to manufacture front panels for kitchens and cabinets, which are an alternative to real wood or painted doors. 3D pressing is a manufacturing process that uses heat and pressure to bond decorative materials to MDF panels or other substrates.

The result is a door panel that is produced much faster than a lacquered solid wood or painted door, with a vinyl covering that is durable  and easy to clean.

As this type of production has become more popular over the years, foils are now extremely authentic with realistic wood effects and matt and high gloss finishes emulating a typical painted product.

These foils have in turn put more demand on the membrane press adhesive industry to create the perfect finish. Type of plastic foils include PVC, PP and ABS.

Unicol adhesives are a crucial component in this process: there are two types of adhesives, one-component and two-component PUR water dispersion. To improve the heat resistance of these adhesives it is necessary to use an isocyanate hardener in either encapsulated form for single component grades, or separately for two component products.

The PUR dispersion is applied to the moulded MDF either with a manual gun or automated spray nozzles. Once dried, the panel is then covered with a PVC foil and placed in a membrane or vacuum press.

The pressure and heat in the press reactivate the adhesive and allow the film to shape itself on the moulded MDF.

Membrane press adhesives are very successful in bonding synthetic materials and natural materials, are water-resistant, dry quickly on the applied surface, and are resistant to high temperature (90°C).
