Deuteron® UV 1240

• Deuteron® UV 1240 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 1240 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 1240 do not affect the film shrinkage negatively because they contain no volatile solvents.

Deuteron® UV 1240 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.

• Plastic canister (20 w net)

• 12 months at room temperature and dry conditions in its original tightly closed containers.
• Do not expose to direct sunlight. Optimum storage temperature is between 10 °C and 35 °C.
• Avoid contact with water and high humidity.
