Ultraviolet (UV) curing uses high-intensity light rather than heat to dry (or cure) and harden coatings, adhesives and inks. Unlike conventional air-drying methods, UV curing does not use solvents and therefore no pollutants are created.
The application of ultraviolet (UV) curing has increased in the last few years, the benefits of this technology are:
A technology that is environmentally friendly, due to reduced use of solvents
Low energy consumption and therefore economical benefits
Compact plant size.
Radiation curing under oxygen-reduced conditions, improves the products properties and reduces the costs. Some of the main advantages of these conditions are:
Reduction of expensive photoinitiators (UV)
Higher curing speed
Lower energy costs
Better scratch resistance
Less ozone formation (EB).
In most cases, nitrogen and in some cases carbon dioxide, is used to eliminate the oxygen in the curing chamber.
We provide a range of solutions to fit your needs, these include: consultation and testing, optimum supply of nitrogen based on the individual specifications decided around economic and technical aspects, required purity, suitable equipment (metering panels) to supply and control the needed amount of nitrogen to the UV or EB unit as needed, including the measuring of the oxygen concentration.
