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 […]

Top Recommendations for Work & Turn Aqueous Coatings

Work and Turn Offset Printing

Work and Turn Offset Printing Work & Turn, (W&T) as we know it, is a process familiar to the sheet-fed printer where the second side of a sheet is printed after the first side. This is accomplished normally by turning the sheet over from left to right using the same edge of the paper or […]

Metallic Cold Foil Graphics Persuades Shoppers

Cold Foil Label

Rapid Productivity Fuels Growth Growth has come rapidly for productivity improving cold foiling. Foiling is known for its ability to add eye-catching visual effects to all aspects of printing creating brand differentiation. Foiling has proven to be effective in attracting and persuading shoppers to choose one product over another. Cold foiling, first developed in the […]

Shipping, Storing, and Handling Aqueous Coatings in Cold Environments

Aqueous Coatings in Cold Environments

A Guide to Shipping, Storing, and Handling Aqueous Coatings in Cold Environments Aqueous coatings, integral to the graphic arts industry, boast versatility in their thermoplastic or thermosetting formulations, whether in solution or emulsion polymer blends. Predominantly water-based, these coatings contain approximately 60% water along with various property-enhancing components. Storing and handling such aqueous coatings in […]

Notable differences between Aqueous Coatings and UV Coatings

Aqueous UV Coating Differences

Aqueous print coatings and UV (Ultraviolet) print coatings are types of coatings applied to printed materials to enhance their appearance, durability, and other functional properties. First and foremost both Aqueous (water-based) and UV coatings have achieved widespread use in the Graphic Arts Industry as competing top coats. Both offer aesthetic enhancement and protection, adding value […]

Is Cleaning up Forever Chemicals like PFAS on the Horizon?

Cleaning up Forever PFAS Chemicals from Drinking Water

Eradicating PFAS Forever Chemicals? Two exciting research developments from UC Riverside scientists, published in the journal “Nature Water”, have given rise to the hope that “forever chemicals” might be broken down and neutralized. The focus is on the subclass of these chemical products (PFAS) that contain chlorine atoms. New research under the leadership of Professor […]

Aqueous Coatings & Foaming

Aqueous Foam

Aqueous Coatings are Complex Blends Aqueous coatings are complex blends of materials with a typical formula consisting of a mixture of aqueous emulsions, blended with additives to improve properties and performance. These additives are commonly, small quantities of an amine, a plasticizer, waxes, a surfactant, coalescent aids, and anti-foam agents.

Mystery of Drying Aqueous Coatings

Aqueous Coating

It’s well known and understood that washed clothing dries when the wash water is evaporated.  Similarly, paint dries when the diluent solvent is evaporated, leaving a film of dry paint solids. Aqueous coatings dry as volatile components (mainly water), about 60% of the typical formula composition, evaporate or are absorbed by a porous substrate.  Coalescence […]

What Is It About Viscosity?

Water Viscosity

Understanding and Testing of Viscosity in Coatings Viscosity tells us how thick or thin a liquid is. Coating viscosity is the property of a fluid that causes it not to flow easily because of the resistance of its molecules. When we use coatings, we need to understand viscosity, because it is key to accurate application, […]
