Cationics
Cationic UV UVACURE® curable resins, based on cycloaliphatic epoxide resins are used to produce solvent-free, environmentally friendly lacquers, inks, coatings and adhesives, offering unique film properties including reduced shrinkage and excellent adhesion.
Typical applications are metal decoration on cans, packaging inks (including aluminum laminating adhesives and overprint varnishes).
As the cationic polymerization reaction continues during the post curing process (also called dark cure effect) practically all of the reactive species are incorporated into the final polymer matrix.
