Technical data

1 - Structure


HPL laminates are produced in sheets or rolls. The upside of each sheet has a decorative layer – unicolour, imitating wood or stone, or a whimsical pattern.

The underneath is pre-polished and prepared for gluing or joining with a carrier board.

HPL contains several layers:

Each layer is made of a different kind of paper, prepared and produced in a different way.

  1. Overlay protective layer - top, invisible layer, special impregnated paper containing corundum. Due to the content of corundum,  HPL possesses the required resistance to wear  and scratches.
  2. Decorative layer – printed paper impregnated with melamine resin. The pattern may  be wood-like, stone, whimsical or unicolour.
  3. Core paper – paper of the highest degree of hardness, impregnated with phenol resin.

2 - Storing and transport


  • HPL SWISS KRONO should be stacked and stored on a flat, firm, and stable surface.
  • Storage surface should be bigger than laminate sheet.
  • Top, last sheet of the stack should be placed with the decorative layer on the bottom and covered with covering panel over the entire surface.
  • Between sheets in the stack there should be no dirt that might scratch the laminate surface.
  • Individual sheets may be rolled up, decorative side facing inwards.
  • HPL should be stored in closed and roofed rooms, protected from humidity.
  • Caution should be exercised during moving and transport of laminate sheets to avoid damaging them.

3 - Room conditions during HPL laminates processing 


Room humidity and temperature have a crucial influence on HPL laminate linear dimension changes.

Optimum conditions:
Temperature: 18-22°C
Air humidity: 50-60 %.

Note: Storage and room conditions during processing have a direct influence on HPL SWISS KRONO laminates gluing and processing results.




4 - Processing


The top surface of HPL SWISS KRONO laminate is made of high-quality melamine resins, thanks to which it is relatively firm.

HPL SWISS KRONO laminate processing should be performed on a stable, flat, even surface.

Laminate should be placed with decorative side up. Do not let laminate vibrate or tremble. Sharpness and proper movement of tools are crucial.

Decorative side cracks, breaks, or bumps result from inappropriate processing or the wrong tools.

Use standard carpenter's tools for cutting, such as circular bench saws, buzz saws, and jigsaws. Remember to follow the saw manufacturer's instructions.

Good quality of the processed edge depends on:

- teeth shape
- teeth number
- cutting speed
- feed speed

5 - Gluing HPL SWISS KRONO


Decorative HPL SWISS KRONO laminates may be used in a variety of ways by gluing them to carrier wood-derived materials..

When making combined elements out of HPL SWISS KRONO and carrier materials, it is crucial to use proper gluing systems matched to the place of use of the finished product.

Before gluing, clean both sides of the laminate and the carrier material thoroughly. All, even the smallest smudges and stains must be removed.

During gluing, follow all adhesive manufacturer recommendations on both adhesive layer application and proper stress.

The following kinds of adhesives are appropriate for wood-derived materials:

Dispersive adhesive

e.g. PVAC = white glue


Condensing adhesive

e.g. urea-formaldehyde/melamine, resorcinol, phenol resins


Contact adhesives

e.g. neoprene adhesives


Reactive adhesives

e.g. epoxy, unsaturated polyesters, polyurethane adhesives


Hot-melt adhesives

e.g. polyurethane hot-melt adhesives

6 - Carrier materials


To create the perfect surface, laminate HPL Swiss Krono should be used (glued) on both sides of the carrier material.

It is recommended to use laminates of the same parameters, particularly the same thickness, on both sides.
Remember to glue opposite laminate sheets to the carrier material in the same direction.

Failure to follow above recommendations may result in material deformation. 


Carrier materials

  • Particle boards
  • MDF
  • HDF
  • OSB
  • Plywood
  • Wooden boards

7 - Cleaning


HPL SWISS KRONO should be cleaned with a damp soft rug or sponge and regular cleaning agents available on the market, e.g. dish soap.

Cleaning agents commonly used in households perform well in contact with laminate if they have no wear properties and do not contain acids or strong alkaline substances.

After washing with standard cleaning agents, laminate should be washed with clean water and dried completely in order to obtain a smooth surface without smudges.

HPL SWISS KRONO is resistant to most stain-causing substances, e.g. milk, tea, coffee, wine, syrups.

Despite the high parameters of HPL laminate, it is recommended to remove remains of all aforementioned products from the surface promptly.

Particular attention should be paid to products such as blueberry juice, beetroot juice, or tomato puree.
