Product Description

 INV 184 is the best choice for non-yellowing application. It is an alpha cleavage type photoinitiator, which
combines the characteristics of high photospeed and exceptional storage life. The non-yellowing and low-
irritating properties make it an ideal choice for clear coatings on paper, flooring, metal, plastics, and wood.

INV 184, when irradiating with UV light, undergoes an intramolecular homolytic breakage to generate a pair of free
radicals to initiate the polymerization of UV curable systems.It does not require hydrogen donor to
initiate its radicals. However its radicals are very sensitive to oxygen in the air.
INV 184 is strongly recommended when non-yellowing properties are crucial. Results obtained from
outdoor exposure study show that it gives better long-term non-yellowing performance than other initiators.
Furthermore, It exhibits lower sensitivity to air inhibition than INV 1173 during curing.
The usage rates of INV 184 vary according to the composition of the system, source of light, line speed, and film
thickness but usually lie between 0.5% to 5% w/w. INV 184 can be used for printing ink, overprint varnishes and
wood lacquers, adhesive, and photoresist dry film.
