Abstract

A coating composition for application to a substrate utilizing a high transfer efficiency applicator is provided herein. The coating composition includes monomeric, oligomeric, or polymeric compounds having a number average molecular weight of from about 400 to about 20,000 and having a free-radically polymerizable double bond. The coating composition further includes a photo initiator. The coating composition has an Ohnesorge number (Oh) of from about 0.01 to about 12.6. The coating composition has a Reynolds number (Re) of from about 0.02 to about 6,200. The coating composition has a Deborah number (De) of from greater than 0 to about 1730.
