Photoinitiator 2959

A Type I photoinitiator designed for UV-curable clear coatings and water-based UV dispersions,with a strong position in low-odor, low-migration formulations for paper, metal, plastics, and selected adhesive applications.

Photoinitiator 2959 is an efficient free radical photoinitiator with high reactivity, low odor, no yellowing, low volatility, insensitivity to oxygen inhibition, and high surface curing efficiency. Its unique active hydroxyl groups can easily be grafted onto polymer molecules and are soluble in water-based systems. It is suitable for varnishes, inks, coatings, adhesives, especially for water-based acrylic esters and unsaturated polyesters.

Photoinitiator 2959 has been certified by the FDA for use in food-contact-free adhesives. The general dosage is 1-5%.

Applications:

• Used in UV curing formulations for wood, metal, plastic and paper surfaces.
• It is particularly recommended for UV formulations where moisture needs to be evaporated through high temperature and gas flow before curing.
