Product name: 2-(4-Methylbenzyl)-2-(dimethylamino)-1-(4-morpholinophenyl)butan-1-one 379
CAS NO: 119344-86-4
Purity:99.9%
Color: Yellow
Formula Weight:380.52
Formula: C24H32N2O2
Application:
Initiator 379 can be used alone or in combination with a suitable initiator (eg Y1610, IRGACURE651) for Uu-curing inks on paper, metal and plastic surfaces.
And the high absorbency characteristic of varnish photoinitiator 379 makes it particularly suitable for curing inks
Initiator 379 is similar in structure to RGACURE369. Compared with RGACURE369, IRGACURE 379 has higher solubility and curing effect, so it is more widely used.
Recommended dosage:
Ink: 2-4% photoinitiator 379
In the light color system, it can be used with Irgacure 819 G1610 for better deep curing effect.
Safety and operation:
Photoinitiator 379 is sensitive to light and should be protected from exposure to sunlight. Open packaging should be resealed as soon as possible.
