Working under the motto “we paint everything”, it is clear that we could not go past glass coating in our research.

Glass, possessing a number of unique properties, primarily the ability to create various optical effects, has always been the subject of interest for specialists in the field of construction, interior decoration, furniture production, etc. Glass coating refers to the “processing” technology, the task of which is to increase the artistic and decorative properties of products. It allows you to create a wide palette of various color solutions, which makes glass as a decoration material even more attractive.

Everyone knows the advantages of polymer powder coating technologies.

Therefore, special attention is paid to glass coating with thermoset powders. Numerous studies have been and continue to be conducted by leading paint developers. And, despite certain successes achieved, gaps in the quality of coating have become a reason for serious and mostly justified criticism. With the development and introduction of new modified thermoplastic paints, noticeable progress has been made in the field of improving methods of powder coating of glass. However, despite their relative attractiveness, the presence of rather complex installations in technological cycles prevents their widespread practical implementation. However, due to the urgent need to solve this problem, it can be stated that a significant technological breakthrough in the field of application of powder paints for glass is predicted in the near future.

We believe that it will primarily be connected with thermoplastic paints. The basis for this statement is our practical experience with thermoplastic paints.

We discovered that when coating glass with thermoplastic paints, in addition to good adhesion, finished products acquire a new property – safety, since the nature of the destruction of such glass is similar to triplex. The powder coating additionally performs the functions of a protective film. We received samples of colored “coating” triplex (a polymer layer of paint was used instead of the classic triplex film ). The obtained results indicate the prospects of this direction and require further theoretical and practical development.

Now we will consider alternative methods of coating glass with liquid paints and varnishes (LPM).

For this purpose, there are several groups of lacquers, the first is paints (enamels based on ceramides ) fired in an oven at high temperatures, the second is a group of air-drying acrylic and polyurethane materials. They can be both water-soluble and dilutable organic solvents.

We use two-component polyurethane-acrylic paint in our work when coating glass. The analysis of the results of practical application showed that the materials provide good mechanical and chemical resistance, adhesion, have a wide range of color shades, their coloring according to the RAL system is possible, as well as a good group of special effects and, importantly, a relatively low cost of the coating process. We carry out solid coating of the surface, and also use artistic stencils, which allow you to get full-color drawings of any complexity.

We have developed and tested the method of high-performance drying of the specified materials in IR ovens.


  • Drying – removal of moisture that is in various connections with the material.
  • Heat treatment – heating the material to activate chemical reactions.

Given the differences in the physical essence of the tasks to be solved, a step-by-step programmable furnace operation mode is used in which the power and, most importantly, the spectral composition of the radiant flow are controlled. At the same time, we get the perfect quality of the painted surface with good adhesion. The full cycle of thermal exposure is 20-25 minutes. The photos show examples of continuous and fragmentary coating. We painted the facade and interior glazing of Shakhtar Hotel in Donetsk.

In addition to simple coating of glass, the interest of designers in creating large-scale full-color images on the surface of glass (and mirrors) is continuously growing. The existing methods of applying a high-quality drawing are not without drawbacks and due to the complexity of the tools used have limited application. Therefore, one of the goals we are pursuing was to show the possibility of solving similar problems with simpler techniques and means, based on the use of the principle of sublimation heat transfer (see the section “Polymer decoration”).

The developed combined method of image formation, which does not require the imposition of restrictions on the size and configuration of the surface, allows you to form an image on a mirror surface with a transparent or matte background.

Experimental testing showed that the resolution achieved with this method on large glass sizes (2500×4000) corresponds to the maximum visual resolution. The photo shows samples of coating and decorating glass and mirrors.

The practical side of the application of the developed method involves an in-depth study of the mechanism of image formation, development and optimization of equipment parameters. We are ready to provide everyone interested with an offer on equipment for sublimation glass decoration.
