Bis-(4-methylphenyl) iodonium hexafluoro phosphateFree from Antimony, faster than UV 3100
Features & Benefits
- CASE Ingredients Features
- Product Highlights
- Deuteron® UV 2257 is a solution of Bis-(4-methyl- phenyl)-iodoniumhexafluoro-phosphate in reactive solvents. Deuteron® photo initiators are suitable for resins based on oxirane and/or oxetane groups (epoxy resins and vinylether. The addition of Deuteron® photo initiators enables the formulator to utilize UV light to induce the polymerisation of the above-mentioned resin systems.
- Deuteron® UV 2257 is soluble in the mentioned binder systems including the standard solvents and reactive diluents. The polymerization is initiated by exposure to UV light in a wavelength range between 220 nm and 250 nm. The maximum absorption is at 240 nm. Suitable light sources are high-pressure mercury lamps that have a high emission in the mentioned area of absorption.
- Deuteron® UV 2257 does not affect the film shrinkage negatively because it contains no volatile solvents.

- Application and Dosage Information
Deuteron® UV 2257 is suitable for a wide range of applications including:
- Overprint varnishes
- UV silk-screen inks
- UV flexographic inks
- UV lamination adhesives
- Metal coatings
- Plastics coatings
The use of Deuteron® UV 2257 especially improves the following properties:
- low shrinkage
- no benzene emission
- only slight odor
- flexibility
- adhesion properties on difficult substrates
Dosage
- Typical addition range: 1.0 % - 5.0 %
- The required dosage level highly depends on the system and the desired curing speed.
- Thus, it is highly recommended to determine the needed addition level by a practical ladder study.
Processing
- Deuteron® UV cationic initiators can be incorporated into the binder with high-speed stirrer or other aggregates, e.g. dissolver.

Technical Details & Test Data
- Absorption Range Data
Like different radical photoinitiators, cationic photoinitiators, which in our case are based on different molecular configurations around the iodine atom, have different absorption spectra. Our initiators have their absorption maximum at about 240 nm. Since the optimal wavelength ranges for initiation are therefore more in the short-wave range, Iron-doped Mercury vapor lamps, are suitable as UVC light sources. However, standard Mercury vapor lamps also emit a high proportion in the short-wave range.
