Glass decoration: the characteristics of finishing lines

There are several reasons for coating glass. Aesthetically decorating the surface of the glass, creating a decorative frame around the panel or implementing specific functional characteristics. Whatever the aim, we have developed equipment dedicated to glass coating which focuses on high-quality application uniformity, transfer efficiency and ease of use. A number of these contain special patented solutions, and the experience we have gathered working with leading global glass manufacturers has led us to play a leading role in specific market segments.

In which sectors are glass finishing solutions used?

Integrated finishing lines for glass are applied in various sectors and use different technologies:

Application fields

Here is a selection of specific products with glass



Glass decoration: technologies

The technologies range from roller coating to spray coating, as well as the drying procedures. Designed in our finishing laboratories around the world, we have implemented patents in the field of spray coating and with regard to solar panels. Our roller coating solutions incorporate a high-performance laser-engraved application roller ensuring uniformity and superior transfer efficiency. Our software solutions also support customers who handle glass, bringing them further benefits in terms of productivity, cost-effectiveness and coating quality.


Applying water-repellent coatings to glass

Until recently, special hydrophobic products were applied to glass surfaces manually. This remains a possibility, but will never be as economically viable as automatic spray coating procedures, which also ensure consistent quality and correct parameter settings to achieve optimum results.

Shower doors, car windshields, glass roofs for bus shelters are all typical applications where a transparent, spotless glass surface is not only an attractive one, but also a functional one. Other applications which benefit from water-repellent surfaces include solar panels to avoid accumulation of particles which reduce solar-cell efficiency and ceramic tiles to avoid limescale build-up.

Tested extensively on our PRIMA spray coater, we have established the optimal parameters to apply these special coatings in a factory-based scenario. One litre of water-repellent coating will cover approx. 40 square metres of glass and can be applied at low pressures.


Achieving quality results

Before exploring single benefits of each machine in relation to the application mode, it is important to know that our approach to glass coating responds to the evolving demands of manufacturers and third-party coating companies who need to achieve top quality results while being faced with the following issues:

  • Ease of use and quick set-up procedures
  • Flexibility enabling frequent coating changeovers
  • Application uniformity and precision
  • Reducing manual tasks through automation and line integration

Frequently Asked Questions

Frequently Asked Questions

01 What are the advantages of roller coating?

High flexibility in terms of output rate and choice of cycles/processes according to the line make-up.

Zero solvent emissions thanks to 95% use of products with high dry residue (UV) content.

Possibility of using the roller technique for any application on all flat surfaces.

02 What are the advantages of spray coating?
Firstly, spray coating ensures all sides of the piece are covered. Secondly, the product shape is unimportant and, since it is not a contact-type coating, different tolerances between products are compensated for automatically.
03 What are the advantages of drying?
Let's talk about the advantages of the whole finishing process, which includes lacquer application and drying. The "finished" item ends up with improved resistance and protection from external agents, as well as a better aesthetic presentation.
04 On which materials can I spray coat?
Any material, bearing in mind two conditions.
  • That the coating must match the substrate material to ensure proper adhesion.
  • That the piece being coated must be able to pass through the machines/systems.
05 Which coated materials need drying?
All coated materials need drying. The type, duration and method of drying differ according to the nature and quantity of the applied lacquer.
