On many German locomotives the control panel labels were printed with black light paint and a black light source was provided in the cab. This left the driver with full night vision while still enabling him to distinguish between the different switches and levers to operate his locomotive. [citation needed] Bodypainting with fluorescent paint
These UV wavelengths are found in sunlight and many artificial lights, but the paint requires a special black light to view so these glowing-paint applications are called 'black-light effects'. Fluorescent paint is available in a wide range of colors and is used in theatrical lighting and effects, posters, and as entertainment for children.
A UV coating (or more generally a radiation cured coating) is a surface treatment which either is cured by ultraviolet radiation, or which protects the underlying ...
Blacklight fluorescent tubes. The violet glow of a blacklight is not the UV light itself, but visible light that escapes being filtered out by the filter material in the glass envelope. A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light.
The addition of reactive diluents facilitates the processing of the lacquers, allows the addition of more fillers and improves the wetting behavior on the substrate. [1] If volatile diluents are replaced by reactive diluents, flammability, smell, skin irritation and environmental compatibility (by lower or no VOC emissions) can be improved. [2]
In printing, organic pigments are mainly used in the inks, so the shifting or bleaching of the color of a printing product due to the presence of UV light is usually just a matter of time. The use of organic pigments is justified primarily by their inexpensive cost compared to inorganic pigments.
UV–vis microspectroscopy is also used to analyze trace evidence, such as textile fibers and paint chips, as well as questioned documents. Other applications include the authentication of various collectibles and art, and detecting counterfeit currency.
Acrylated urethane oligomers are typically abrasion resistant, tough, and flexible, making ideal coatings for floors, paper, printing plates, and packaging materials. Acrylated polyethers and polyesters result in very hard solvent resistant films, however, polyethers are prone to UV degradation and therefore are rarely used in UV curable material.
