In June, Fusion UV Systems Inc., Gaithersburg, Md., was granted U.S. patent 6,908,586 B1, "Free Radical Polymerization Method Having Reduced Premature Termination, Apparatus for Performing the Method, and Product Formed Thereby." The patent supports the company's Light Hammer line of high intensity UV lamps for industrial UV curing. It applies to the enhanced level of curing that results when substantially constant UV is used to cure coatings and inks.
David Harbourne, president of Fusion says, "We're anticipating this can have a significant impact on existing and new UV chemistries. Some customers are already getting improved product quality and performance using the Light Hammer UV curing system."
