Environmentally friendly, low cost, aesthetically attractive and high durable decorative coatings

Decorative coatings provide attractive and aesthetic appearance to the products. They are applied to buildings and associated structures for decoration and protection.

The market for decorative coatings is based on the rapid urbanization, increasing demand for colorful and glossy appearance and an extreme increase in investments in infrastructure are propelling the growth of the building, construction, and fashion industry in developing and developed countries.

The reconstruction & renovation projects in the building sector drive the global decorative coatings market during 2022 to 2030 to almost 100 billion by the end of this decade.

The global decorative coating market can be segmented based on the different kinds of products, materials, coatings, technologies and importantly by application.

Benefits of PVD techology

Based on customers’ interests, the focus is given to luxury and home (product), with inorganic oxides and nitrides of metals (materials), exterior (coatings) done by Physical Vapour Deposition - termed as “PVD” (technology) for both residential and non-residential applications.

For last four decades, environmental scientists have been making many alarms that the electroplating of finishes, such as hard chromium, cadmium and nickel in metal finishing have been recognized as a major source of environmental pollution in every country.

Since last three decades, the development of ‘environmentally clean’ technologies in all aspects of industrial manufacturing has been an essential task required and initiated by environmental laws and restrictions tailored by several countries around the world.

Electroplating of decorative and protective coatings stays one among the top sources of environmental pollution.

Despite stringent government laws, electroplating is still surviving through strong lobbying court orders as hard chrome became easily and commercially available and electroplating-based industrial manufacturing has developed into a huge, well-organized, sophisticated and financially mammoth multi-billion-dollar sector.

At least for last few years, strong activities are initiated with an objective to systematically replace some of the ‘environmentally dirty’ technologies (especially for cadmium, chrome and zinc) with high performance dry coating ‘clean’ methods.

Among many available technologies for decorative coatings, the highest focus has been given on physical vapour deposition (PVD), chemical and plasma-assisted chemical vapour deposition (CVD, PACVD) and thermal spraying.
