Cationic Cure Flexographic Ink — TWG-FXUCAT

A cationic cure flexographic ink is chosen when a label job will not stay put on an ordinary film or foil, and TWG-FXUCAT is Triwill Group’s grade for that problem.

Triwill Group supplies UV Flexo Cationic through partners and distributors in the UAE and GCC, on a quote-led basis. Technical data sheets are available on request, with a technical and commercial study behind each recommendation.

Key Features

• Cationic UV cure: A curing chemistry in which the reaction initiated by UV light continues after exposure.
• Strong adhesion on difficult substrates: Formulated for films and foils that present a smooth or low-energy surface.
• Reduced cure shrinkage stress: Cationic curing is associated with lower shrinkage than some free-radical systems.
• Flexo label production: Made for narrow-web flexo label and packaging lines.
• Colour and print quality: Colour strength and print definition suitable for label work.

Frequently Asked Questions

What is a cationic cure flexographic ink?

A cationic cure flexographic ink is a UV flexo ink whose curing reaction is initiated by UV light and continues after exposure. That continued cure is associated with strong adhesion and lower shrinkage stress, which is why the grade is specified for difficult films and foils.

Which substrates is TWG-FXUCAT made for?

TWG-FXUCAT is made for difficult films and foils where ordinary UV flexo grades may not adhere well enough. The exact substrate should be named when requesting a quote, including any surface treatment it has received.

How is cationic curing different from ordinary UV curing?

In ordinary free-radical UV curing, curing largely stops when the light stops. In cationic curing, the reaction continues after the lamp has passed, which supports adhesion and helps limit shrinkage stress on the cured film.

Who should buy this grade?

Partners and distributors come first, since they supply label printers and converters and need a specialist grade they can discuss and document. Label printers and flexible packaging converters working on difficult films and foils are the next audience.
