Bolingbrook, IL, April 2001 Radiation curing of ultraviolet acrylates is now practical in production environments when two equipment concepts from IST America the North American subsidiary of IST Metz are combined.  By using IST America stepless lamp controls in combination with IST America continuous measuring equipment, the application of hot melt pressure sensitive adhesives can be controlled precisely, thus eliminating overcuring (which reduces adhesion) and undercuring (which yields high adhesion, but low cohesion).  Practical demonstration of the precise control concept offered by IST America was disclosed in a paper presented at CMM International 2001, the packaging exposition held in Chicago April 23-25, 2001, by Rolf Müller of IST METZ GmbH, the parent company of IST America.  In discussing the concept, Andrew Stott, IST America vice president of sales, commented: With several installations now in place, the practicality of ultraviolet acrylates in high speed production environments has been demonstrated.  Each installation must be carefully engineered and designed to yield the desired production results, a strength of the IST America application team.
