type of photo initiator was shown to induce fast crosslinking with the UV irradiation in natural sunshine, and carefully selected peroxide also provides crosslinking speed fast enough for a coating application.
A relatively newer PI technology, BAPO
(not listed), was not evaluated for color stability because of its insolubility in cosolvents, and a water-dispersible BAPO
displayed negative effects on gloss presumably due to incompatibility.
Thus, BAPO is desirable for long wavelength (up to 430 nm) photocuring.
It was found (10) that when BAPO is used as the photoinitiator, up to 25 mil thick gel coats (containing 15 wt% Ti[O.

(bisacylphosphine oxide) technology.
