Exploring Material Properties of Friction, COF, Slip, and Slide Angles

Slide

Opposing, as they are, friction and slip are key to much of what functions on Earth. Without friction we would not be able to walk, we would slip, and slide with little control. Driving relies on tires to maintain a grip on pavement giving us vehicle control through friction. Brakes control our ability to stop […]

Electron Beam Applications’ Expanding Footprint

Electron Beam Applications Chart

Electron Beam (EB) does a lot of things, but perhaps the most significant one is the ability to break bonds of polymers.  When chemical bonds are broken, they produce free radicals (unpaired valence electrons), which are the drivers of free-radical chemical reactions.   These are the basis of the majority of present-day commercial EB applications.  An […]

Aqueous and UV Coatings Tricks to Cleanup Process

Printing Separation

Aqueous and UV / EB Coatings have distinct cleanup methods that can make the processes run better.  This article will address specific tricks to cleanup before, during, and after press runs of aqueous, UV, and EB Coatings. Safety First and Second We will tackle the important steps in the cleanup of coatings for both Aqueous […]

Measuring Durability in Coatings with Abrasion Testing

Not a proper abrasion test!

How do we best test to predetermine the durability of printed/coated graphic arts products? Abrasion tests can determine the durability of printed and coated graphic arts. The durability of a printed coating is typically defined by such terms as, scuff, wear, rub, smudge, abrasion, blotching, and/or pick-off resistance. Historically a problem, defacing abrasion damage is […]

Trends that affect Printing and Coating Markets Covid-19 Accelerates Trends in Printing and Coating Various trends are in place that are now and will continue to affect printing and coating markets. Covid-19 has acted as an accelerant for these trends. When the initial reaction to Covid-19 locked-down world wide economies, businesses closed, people stayed home, […]

Testing the Cure of Electron Beam Coatings (EB) & Ultraviolet Coatings (UV)

MEK Rub Test

The UV and EB Curing Process Prior to discussing the testing of the cure of UV/EB curable coatings let’s review what UV/EB curing is. Curing or polymerization is the process of reacting prepolymer monomers and oligomers together in a chemical reaction that forms polymer chains, or cross-linked three-dimensional networks. UV curing is a process that […]

eGreen™ High Gloss EB Coating

eGREEN™ is a high gloss, flexo, or rod applied, zero VOC, environmentally responsible, fast curing, workhorse EB curable green coating designed for application over a variety of substrates. Unlike conventional EB coatings, which are typically 100% petrochemical resource-based, eGREEN™ is made using abundant Green renewable bio-resource content. Properly applied and cured, eGREEN produces a smooth glossy, […]
