From ancient times light has been used as a guide, as safe route and as a general everyday solution. Light has always been a natural means of distinguishing the phases of days and nights, measuring the unstoppable flow of time and allowing us to navigate using the stars, even in the darkest of places.
Light is also synonymous with divinity, spirituality, purity and magic. Light is an element full of real and surreal qualities that, through human beings' imagination, creativity and thirst for knowledge, has enabled the evolution and major transformations of life.
Light allows us to explore and observe the universe; from the smallest particles to the most distant stars. Among other things, we can send digital information to every part of the world, eternalize fleeting moments through photographs and look through bodies to enable medical assistance. Qurtech contributes to the world of technological innovation by specialising in ultraviolet light curing through the imagination, creativity and thirst for knowledge of the people who work with us.
Ultraviolet light curing
Ultraviolet light curing is a rapid drying process, which uses high intensity UV light to initiate a photochemical reaction that, through crosslinking, "dries" coatings, adhesives and inks instantly. Originally introduced in the 1960s, this technological process has given way to the streamlining and speeding-up of manufacturing in many industries. This is a highly versatile process which, due to its distinctive traits, such as low-temperature processing, high-speed curing/drying* and low (sometimes zero) emissions, can be used for many different applications, including printing, coating and assembling.
The main advantage of UV curing lies in its drying speed* and properties and consequently in its potential for a finished product to be immediately reprocessed and/or packaged and subsequently shipped. In addition, lowering the time of the entire process significantly reduces reject rates and the occurrence of defects. This is due to the part's shortened exposure time to dust particles and impurities contained in the air. This characteristic increases the quality of the finish, the consistency and the robustness of the process. Another benefit of UV technology is that it allows for a contained, compact and very efficient production area. This impacts the entire manufacturing process, often permitting a higher quality finish than other, more traditional, systems and technologies can achieve.
