H-Nu-IR Photoinitiators -- 700 - 850 nm infrared absorbance
Spectra Group Limited is proud to announce two new IR (infrared) photoinitiators with absorbance in the 700-850 nm range. H-Nu-IR 780 and 815 have excellent solubility in a variety of acrylate monomers and exhibit strong bleaching leading to a final polymer with little or no color. They cure via a free-radical mechanism and do not require an amine coinitiator. Cure using infrared sources or cure through IR filtering substrates is possible. Ask us about the newest IR/Infrared additions to the H-Nu family of photoinitiators --contact us by phone (419) 837-9783, fax (419) 837-6816 or email.
H-Nu-Blue Visible Light Photoinitiators -- 575-700nm absorbance
Spectra Group Limited is proud to announce two new photoinitiators with absorbance in the 575-700 nm range. H-Nu-Blue 640 and 660 have excellent solubility in a variety of acrylate monomers and exhibit strong bleaching leading to a final polymer with little or no color. They cure via a free-radical mechanism and do not require an amine coinitiator. Cure using red lasers or cure through red colored substrates is possible. Ask us about the newest additions to the H-Nu family of photoinitiators --contact us by phone (419) 837-9783, fax (419) 837-6816 or email.
