UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. UV curing is a low-temperature, high speed, and solventless process as curing occurs via polymerization. [2] Originally introduced in the 1960s, this technology has streamlined and increased automation in many ...
UV coatings advantages in this application can be summarized as faster, smaller, and cleaner with no thermal ovens required. The coating and curing (almost instantly) at speeds ranging from 100 feet per minute to over 800 feet per minute so the faster production speeds provide greater opportunity for return on investment for the customer (ROI).
In ionic curing processes, an ionic photoinitiator is used to activate the functional group of the oligomers that are going to participate in cross-linking.Typically photopolymerization is a very selective process and it is crucial that the polymerization takes place only where it is desired to do so.
In chemistry, a photoinitiator is a molecule that creates reactive species (free radicals, cations or anions) when exposed to radiation (UV or visible). Synthetic photoinitiators are key components in photopolymers (for example, photo-curable coatings, adhesives and dental restoratives).
Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...
UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. In comparison to other technologies, curing with UV energy may be considered a low-temperature process, a high-speed process, and is a solventless process, as cure occurs via direct polymerization rather than ...
The next type of curing light developed was the quartz-halogen bulb; [4] this device had longer wavelengths of the visible light spectrum and allowed for greater penetration of the curing light and light energy for resin composites. [3] The halogen curing light replaced the UV curing light. The 1990s presented great improvements in light curing ...
Heat-sensitive carbon fiber tubes coated with a UV curable powder coating. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
