The world continues to embrace initiatives fostering more environmentally friendly “green” processes, and the converting industry is not exempt from this pursuit. All aspects of the converting process are being scrutinized, including the need to make the adhesives and sealants component of converting more environmentally friendly.

Ultraviolet (UV) coatings are cured by UV light. They contain almost no solvents that may evaporate during the curing process. Instead, the UV curing process is achieved through polymerization—a crosslinking reaction of the coating constituents.

The photo curing extent of styrenic block copolymer (SBC)-based adhesive formulations applied as a uniform layer on a Mylar film can be readily determined by Fourier transform infrared spectroscopy (FTIR).

“The Loctite^® Equipment Sourcebook,” vol. 9 is an updated, 102-page catalog presenting the complete line of Loctite dispensing and curing equipment.

Sometimes deviations from the evenness and uniform smoothness of UV/EB cured surfaces may be an indication of an imperfect coating process.

Regulations play a prominent role in shaping business decisions and spark end user interest in UV/EB technology.

Global specialty chemical manufacturer Sartomer USA, LLC, will hold its recurring technical seminar on ultraviolet light and electron beam (UV/EB) curing chemistries at The Desmond Hotel in Malvern, Pa., near Philadelphia.
