Technology

Digital printing itself is not an innovation anymore. It has been in use in many different industries like printing & packaging for quite some time.  The use of Digital Printing Technology in the flooring and furniture industry however is a true innovation. 

The crucial difference compared to common indirect printing technology is the application of a digital printer, printing the desired image directly onto the (pre-finished) substrate. The water or UV-based ink is applied onto a water or UV-based receptive layer in a single pass or even multi-pass process. The colorless performance coatings above the decor are usually done with UV varnishes. In the meantime, digital printing is entering the third dimension - the 3D systems from Klumpp Coatings, which are tailored to the new system processes, are the benchmark here!

Added value

  • No matter whether it is paper, wood, HDF, MDF, Vinyl, WPC, multiplex, particle boards, mineral fiber or vinyl – Klumpp Coatings‘ adhesion promoter provides perfect bonding to almost every substrate.
  • Klumpp Coatings aqueous and UV-based printing sealers offer the best receptive properties for digital printing with water or UV-based as well as hybrid ink systems.  Our close contacts to all manufacturers of digital printers for industrial use, as well as the know how we gained through our experience, not only make sure you have the right line layout tailored to your requirements. You will also achieve excellent printing results in terms of clarity, deepness and brilliance.
  • Our field-tested clear UV performance coatings are capable of covering every conceivable stress class economically - right up to class 34. 
  • There are practically no limits to the surface design either: gloss levels between 4 and 95 units or three-dimensional surfaces.

Coating system

Primer

Primers are used for direct adhesive bonding between the substrate and the coating structure that is applied subsequently. The applied primers adhere to a variety of substrates and are formulated to be waterproof.

In addition, there are special adhesion primers, which are applied after the application of the printing inks, thus fixing them and integrating them ideally into the overall structure via their adhesive bond.

UV Putties

UV putties are used to fill in irregularities. They are an absolute must when wishing to present smooth, homogeneous surfaces, as required in digital printing.
Klumpp Coatings offers the following putty types: 

Light UV putties which can be fed in with commercial membrane pumps and can be applied in a cycle. This setting makes it easy to handle. 

Heavy UV putties which are usually applied with closed jaws and have exceptional attributes in terms of filling capability.

UV Sealers

In the digital printing process, a distinction is made between the UV primers, which are used before the digital printing to fix up the digital print layer and those that follow the digital printing to enable a high degree of abrasive strength .

Before digital printing:

Coloring UV sealers as printing base.

UV sealers to fix up the digital print layer for a precise, sharp print image.

After digital printing:
SIS-UV sealers have been especially developed by Klumpp Coatings to the Swedish Industrial Standard (SIS).  They enable a high degree of abrasive strength according to the Falling Sand method. 

Anti-abrasive UV sealers achieve the best abrasion results according to the sandpaper technique  (S429..  

UV sanding sealers make efficient lacquer sanding possible.

3D Structure & Pore-filler Coatings

DPL floorings provide maximum product diversity. On top of that, the visual and haptic appearance of the surface can be varied by a 3D-structured surface. 

There are several methods for this, which we can all be mapped with our coating systems:

  • Roller process - the coat is applied with a specially engraved roller.
  • Embossing - deformation of the incompletely cured UV varnish via calander rolls / press plates.
  • Release film - a patented process whereby a transparent, structured film coated with liquid UV varnish is placed in the liquid varnish on the substrate. The film and substrate are combined under a calander and pass under the UV lamps. The hardening takes place through the foil, which is pulled off again after the radiators.
  • 3D digital printing - either with (transparent) UV ink on the hardened paint film or with a special ink, which is printed on the liquid paint film and - through a chemical incompatibility - gives this a desired structure, which must be subsequently fixed with UV lamps

Topcoats

In industrial coating of flooring, the topcoat must be regarded as being of particular importance because it fulfills several important functions at the same time, and as a finish is mainly responsible for how the surface look is assessed. 

Anti-scratch topcoatshave been developed by Klumpp Coatings.  In 1995 we were demonstrably the first coating manufacturer to apply this innovation to parquet applications. They have since become the state of the art. They are based on the very latest nano-particle technology which offers optimal levels of scratch resistance.  The topcoat not only offers anti-scratch protection, but also gives the surface the desired glossiness and homogenous look.   Klumpp Coatings topcoats are known as being very pleasant to the touch. 

Micro-bevel coatings

Klumpp Micro-bevel coatings are universally applicable with different application systems (vacuum, crown wheel, spray head, etc.).

The specific adaptation of the formulation to the respective field of application fulfills all required properties to a very high degree:

  • Color adjustment to basic colors of the decor
  • High filling power with only one application
  • High chemical and water resistance
  • Very user-friendly
  • Highest running stability
  • No sticking together of the filters
  • Low set-up costs
  • No drying of the nozzles
  • Low cleaning effort
