Abstract
UV curable coatings are becoming an increasingly popular alternative to conventional coatings. Compared with thermal coatings, UV coatings provide a number of benefits to plastic part manufacturers including enhanced appearance, improved performance, and various process worker safety, and environmental advantages. But, same high speed curing and highly-crosslinked chemistry that underlie these benefits can also make adhesion failures more likely. This paper examines the problem of adhesion common to UV curable liquid and powder coatings, and describes some tradeoffs associated with popular methods to reduce adhesion problems. Atmospheric plasma provides an especially attractive method of enhancing adhesion of UV cure coatings to a wide range of plastic materials.
Background
Since the early 1970s, UV curable coatings have gained slow, but steady acceptance as an alternative finishing technique for a wide range of substrates from wood flooring, to glass optical components, and from pipe and tube to plastic cosmetics containers. Today for exam
