UV-curing of coatings

UV Curing of Coatings and Inks on Cylindrical-Shaped Parts... 

Photoinitiated polymerization and crosslinking of monomers, oligomers, and polymers constitute the basis of important commercial processes with broad applicability, including photoimaging and UV curing of coatings and inks. 

UV Cure Mechanisms. There are two fundamental mechanisms for the uv curing of coatings free radical and cationic. The more common free radical mechanism consists of a chain reaction with four primary steps ... 

The second patent [94] does not give further information about the synthesis but describes an application of these products — UV curing of coatings for optical fibers. Telechelics diols are used as coreagents for cationic polymerization of epoxy resins. Such coatings are composed of ... 

It has now been well established that UV-curing of coatings can be achieved and there have been many references in the literature as to the development and descriptions of these coatings and the UV-curing art. Most of these literature references describe commercial curing of clear finishes as well as UV-curable inks. This paper explores some of the parameters associated with non-ink low viscosity pigmented UV-curable coatings ... 

UV curing of coatings and printing inks is based on photocrosslinking by photoinitiated radical and cationic polymerization." Whereas monofunctional monomers polymerize to linear polymers, multifunctional, e.g. di- and tri-functional, monomers and oligomers are required to produce a crosslinked polymer network.
