JRCure 1521 is an efficient type I macromolecular α-aminoketone photoinitiator with low migration, low odor, high activity, low yellowing,etc. It has good solubility in monomers and oligomers. JRCure 1521 is recommended for use in plastic coatings, adhesives, lithographic printing inks, screen printing inks, flexo printing inks, electronic products and other fields. Since the yellowing is very low, it can be used in varnishes, and can also be used in colored systems with type II photoinitiators such as 1508. The recommended amount is 3-5%.

JRCURE 1055(MBF) is a versatile highly efficient Free Radical Type I non-yellowing liquid photoinitiator which is used to initiate the UV polymerization of chemically unsaturated prepolymers (e.g. acrylates) in combination with mono- or multi-functional vinyl monomers and oligomers.

JRCURE 1065(BDK) is a highly efficient UV photoinitiator with serious yellowing performance, generally not used for varnish system. It can be used in photosensitive resins printing. It is a yellow crystalline powder compatible with unsaturated polyesters, acrylate monomers and oligomers used in UV-curable systems.

JRCURE 1110(TPO-L) is used as an initiator for very low yellowing, white pigmented UV-lacquers, UV screen printing inks, UV offset and UV flexo inks, overprint varnishes, paper lacquers, photoresists, printing plates, stereolithography, etc. It can be used to cure paints and surfacers pigmented with titanium dioxide. It provides very low yellowing, low volatility and low odour.
