Bayer's UV-Cure Coatings Technology from A - Z

Indianapolis, IN, May 07, 2012 --(PR.com)-- Ultraviolet-cure (UV-cure) coating technology continues to gain traction in the coatings industry due to its many competitive advantages – low energy costs, no pot life issues, reduced environmental impact and a fast cure time, among others. Formulators are looking to capitalize on this technology and optimize its performance.

To give formulators a better understanding of UV-cure coating technology, Michael Dvorchak, manager – intellectual property & new media, Coatings Adhesives & Specialties, Bayer MaterialScience LLC, led a two-part session, “Tutorial 3: Radiation Curing,” from 8:30 a.m. - 10 a.m., Monday, May 7, during the pre-conference tutorial session at the American Coatings Show (ACS).

Generally, the tutorial provided a concise overview on the fundamentals of radiation-curing coatings, their benefits and limitations, as well as the basic chemistry involved and appropriate applications.

During “Part I: Basic UV-Cure Coatings Technology,” attendees learned about the fundamental principles of free-radical chemistry as it centers around the use of 100 percent solids UV-cure aromatic/aliphatic polyurethane, epoxy, polyester, and polyether oligomers. Dvorchak also discussed their use with monomeric acrylates in combination with specific photoinitiators. In addition, he addressed the issues of surface inhibition on free-radical chemistries, and techniques that limit this problem. Other topics he highlighted include UV light sources and curing highly pigmented UV-cure coatings.

“Part II: Advanced UV-Cure Coatings Technology” focused on more advanced UV-cure coatings systems. For example, Dvorchak discussed the development and use of UV-curable polyurethane dispersions, UV-A transportation coatings, UV direct-to-metal applications, UV-cure plastics coatings and UV site-applied flooring. He also reviewed the development of a UV-A cure aerospace coating, as well as the formulation of new, more environmentally friendly UV coatings and their application in new and emerging markets.
