Tytan AP910D is an ethyl citrate zirconium that can be used as an adhesion promoter for printing, crosslinker for paints and as a catalyst for esterification. Due to its chelated structure, Tytan AP910D shows delayed reaction at ambient temperature and thus facilitates storage stability of inks. Compared with organo-titanate adhesion promoters, it shows good compatibility with PVB, CAB and CAP inks and provides minimal discoloration during the sterilizing process in the printing of milk pouches.
As the temperature increases above 60oC, the zirconate can interact with functional groups such as -OH, -COOH, -NH2 in the polymer or substrate.
