The use of vinyl ethers as reactive diluents for cationically cured UV formulations was one of the key factors in the original development of these systems. The fact that they homopolymerise cationically was of unique advantage in their use as reactive diluents for epoxy oligomers. Their remarkable diluency, compatibility and reactivity with a variety of cationically cured epoxy resins was first demonstrated in the late '80s. (Ref. 1)
Since then, further formulation development has widened the scope of vinyl ethers and there are now cationic formulations for printing inks, release coats, metal and plastic coatings as well as many other new exciting applications. (Ref.2)
Whilst the growth in vinyl ether use now also encompasses free-radical and hybrid chemistry, cationic reactions answer many of the problems of adhesion and rheology which remain unsolved by these techniques alone.
This paper intends to describe some of the formulating technology and its applications in a little more detail.
