The selection of an IR Absorber for use in inks depends on several Factors: Wavelength of the detector – If the detector is set to read at say 990 nm, then you need a substance with good absorbance at 990nm. Solubility of the Absorber in the ink vehicle. The aminium IR absorbing dyes have relatively […]

UltraViolet light absorbers have been known to formulators of inks and coatings, for some time, as a necessary additive to protect the ink or coating from the long term degrading effects of sunlight. Infrared absorbers have been known only to a small group of formulators of inks and coatings. However, as the laser finds increased […]

UltraViolet light absorbers have been known to plastic formulators, for some time, as a necessary additive to protect plastics from the long term degrading effects of sunlight. Infrared absorbers have been known only to a small group of plastic formulators. However, as the laser finds increased application this relatively unknown group of additives is increasing […]
