- Product Highlights
- Deuteron® UV 1242 is solutions of Bis(dodecylphenyl)-iodoniumhexaflouroantimonate 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 1242 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 1242 do not affect the film shrinkage negatively because they contain no volatile solvents.
Applications & Uses

- Adhesive & Sealant Type
- Coating Type
- Ink & Toner Type
- Use Level
- 1.0 - 5.0 %
- Application and Dosage Information
Deuteron® UV 1242 are 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 1240 and UV 1242 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. Please note that there are several options to further improve the performance of our Deuteron® photo initiators. This includes the use of co-catalysts (e.g. ITX), catalysis by Copper-naphthenates, increasing the curing temperature and addition of multifunctional alcohols (e.g. TMP).
Processing
- Deuteron® UV cationic initiators can be incorporated into the binder with high-speed stirrer or other aggregates, e.g. dissolver.
