UV Cure Coatings: A Short Course

Instructor:
Michael Dvorchak, Bayer MaterialScience

Course Description:

Part I: Basic UV Cure Coatings Technology
This first session highlights the fundamental principles of free radical chemistry as it centers around the use of 100% solids UV Cure Aromatic/Aliphatic Polyurethane, Epoxy, Polyester, Polyether oligomers and there use with monomeric acrylates in combination with specific photoinitiators. This concept will be further refined to show the use of the oligomer technology without acrylated monomers. The course will look at the issues of surface inhibition on free radical chemistries and techniques to limit this problem. UV light sources will also be reviewed and will include the following: full spectrum UV light sources, UV A light sources both in automotive and industrial settings, fluorescent UV lights and UVA LEDs. Techniques will also be described on how to ensure that equipment and light sources are evaluated for there optimum performance. This section will close out on the technique of curing highly pigmented UV Cure Coatings.

Part II: Advanced UV Cure Coatings Technology
This second session focuses on more advanced UV Cure coatings systems. The course will provide a look at the development and use of UV dual cure 2-Component Polyurethanes and their use in the automotive industry as automotive clear coats. In addition the automotive refinish industries move to the use of UVA light technology for use in rapid repair of body putties, primers and clear coats. This session will also show some of the initiatives of the RADTECH /I-CAR UV to move this technology out into the market place. A review of the development of a UV A cure aerospace coating will also be describe. The session will round out looking at some of the newest technologies that use water and high MW polymers that are really the green of the green coatings technologies. Discussions will focus on how these UV coatings are formulated and used/applied for new and emerging markets.
