Three new pigments for packaging and other applications are said to offer increased strength and reduced formulation costs. They were developed by Engelhard Corp., Iselin, N.J., which on Aug. 1 became BASF Catalysts LLC. Rightfit Yellow 1220 is a green-shade yellow azo pigment that is reportedly heat-stable to 500 F in masstone, 525 F in dark tints, and 550 F in light tints. It is suitable for blown film, bottles, injection molding, and rotomolding. The other two pigments are the newest additions to the Synergy line of proprietary pigments, which are created by optimizing organic and inorganic pigment chemistries around desired properties and are said to be economical alternatives to more costly pigments in the same color space. Synergy Scarlet 6012 is a strong yellow-shade red that is FDA compliant for use in food packaging. It is a coprocessed azo pigment that is heat-stable to 550 F. Synergy Yellow 6261 is said to be the greenest yellow in the Synergy line to date. It is heat-stable to 525 F in masstone and tints and was developed for plastics packaging.
