Abstract
Solvents used in coatings may contain substances that are hazardous to health and the environment. An alternative solvent free technology uses plasma and powder materials to obtain high quality coatings with variable thickness, on various surfaces. The technology is also applicable for 3D objects.

Hazard Assessment
Substance to be substituted: The term "organic solvents" covers a wide variety of organic substances. Many of them have a relatively low boiling point and a high vapour pressure. Organic solvents can be carcinogens, reproductive hazards, and neurotoxins. Alternative substance: As an alternative plasma and powders are used under controlled conditions, that can contain hazardous substances and no final assessment can be made here.
Description of Substitution
The technology uses non-toxic plasma gases (air, nitrogen, argon) and micro-size powder (0.1-20 microns) to obtain high quality coatings. Unlike other technologies, the alternative described in this case enables the continuous and agglomerate-free conveyance of the coating powders into the plasma gas. The powders can be metallic, semiconductor, compound semiconductors, polymers. The coatings can be applied on various substrates such as: paper, cardboard, textiles, glass, metal, ceramics, polymers or wood. The coating thickness range is 1-20 micrometres. The technology can be used for 3D objects as well as for larger surfaces, when several parallel equipments may be needed.
Case/substitution evaluation
The technology avoids using solvents that may contain hazardous substance like carcinogens, mutagens and reprotoxicants. Some of the solvents are hazardous for the environment and may generate large amounts of volatile organic compounds. Being highly automated and used in controlled conditions, the alternative reduces operator exposure. It eliminates the costs of solvents supply, transport, storage and safe use, as well as those for abating their emissions and managing their wastes. The substitution involves investment costs and appropriate training of operators.
