Cytec has introduced in Europe a new silicone-free slip additive designed to enhance the performance of UV-curable overprint varnishes (OPVs). The new additive, Ebecryl 341, targets the need in the graphics industry for OPVs that provide slip, but still must be receptive to inks. Currently available slip additives contain silicone, an ingredient that dramatically decreases ink receptivity on surfaces.
In addition to being silicone-free, Ebecryl 341 additive is UV-curable, and is highly compatible with existing UV- and EB-curable formulations. As a result, the new additive allows ink manufacturers to formulate OPVs that cure instantly when exposed to ultraviolet light or an electron beam source, providing outstanding processing and finishing characteristics, with minimal impact on the environment. In development testing, Ebecryl 341 was shown to impart excellent slip characteristics between cured coatings, and was even more effective in certain cases than the silicone-based additives it replaced.

Ross Ships New Dual Shaft Mixer Design
Ross recently shipped a new dual-shaft VersaMix design incorporating a special helical agitator and high-speed dispersion blade. This combination of agitators provides improved axial and radial turnover of the materials being mixed, applying high shear to the product. This feature is especially useful for viscous materials that have poor flow qualities, the addition of powders that have a tendency to float on the surface and when heat transfer of the batch constituents is important.
The helical agitator is designed for bi-directional operation. Teflon scraper assemblies are attached to the outside of the anchor agitator to facilitate scraping of the sides and bottom of the vessel, when operating in either the forward or reverse direction. The VersaMix can also incorporate a High Shear Rotor-Stator Mixer. The Model VMC-100 includes an air/oil lift that raises the agitators out of the mix vessel.

Gardco Offers Palm Probe
Gardco offers the Palm Probe production ambient light measurement system. The Palm Probe radiometer addresses UV measurement and process control in areas where it has been difficult to pass a radiometer through the process. It has a wide dynamic range, allowing it to read from very low levels of UV light as in fluorescent bulbs to very high levels of UV found in powerful UV curing systems. It is designed to withstand the physical conditions of the UV curing chamber as well as protect the operator and instrument from damage or electric shock.
