How Foam is Formed Foam consists of bubbles that are formed when air or a gas is trapped in a liquid or solid substance. Certain conditions are required for foam to be formed. Mechanical work or agitation is required, as are surfactants that reduce surface tension, so that work increases surface area. Also, foam must […]

First and foremost both Aqueous (water-based) and UV coatings have achieved wide spread use in the Graphics Arts Industry as competing top coats. Both offer aesthetic enhancement and protection, adding value to a variety of printed products.
Why Prop 65? In California, Prop 65 requires the state to publish a list of chemicals known to cause cancer, birth defects or reproductive harm. The law requires a warning label on anything containing these. Benzophenone was listed in 2012. Benzophenone (BP) or Benzo, has been generally recognized as the most used Photoinitiator (PI) globally. […]
UV/EB Materials Since March 2008, Ultraviolet (UV) and Electron Beam (EB) ink, coating and adhesive formulations have been used in direct contact with food products. The change came about due to the efforts of the RadTech Food Packaging Alliance which was able to obtain FDA clearance for a number of UV/EB raw materials. This important FDA […]
Cork Industries Formulates Benzophenone Free UV Coatings Photoinitiators (PIs) are a key component and a cost driver for UV curing products. They are capable, as their name implies, of initiating or starting a photoreaction. This occurs when a PI absorbs radiation energy from light exposure to produce highly reactive free radicals and ionic species. These […]
Work & Turn Work & Turn is a term used to describe the sheetfed litho practice of printing on both sides of a substrate. Typically, the first printing pass prints one side of the substrate. A second printing press pass follows as the job is turned and fed through the press again. The second pass […]
