Printing Inks

Catalysts for printing inks

Titanate-based catalysts from Dorf Ketal, specifically the Tyzor® line, are widely recognized in the printing ink industry for enhancing performance and enabling formulation flexibility in demanding applications such as flexible packaging. These inks—commonly used in gravure and flexographic printing—require not only excellent adhesion to low-energy substrates like polypropylene (PP), polyethylene (PE), and metal foils but also superior resistance to solvents, water, and heat. Tyzor® catalysts are a critical enabler in meeting these requirements.

At the core of this performance enhancement is the ability of organotitanium compounds to act as multifunctional additives—serving as adhesion promoters, crosslinking agents, and surface modifiers. When incorporated into NC-based (nitrocellulose) or polyurethane resins, Tyzor® additives significantly improve the cohesion of the ink film and the bonding to difficult substrates such as corona-treated OPP and PET. Laboratory testing using standardized adhesion protocols, including the Tesa tape test, has demonstrated that formulations containing Tyzor® AA-75 or similar chelates outperform untreated systems by a wide margin, even after short drying periods at elevated temperatures.

Smart Reactivity for Printing Inks

Smart Reactivity for Printing Inks

The enhanced lamination bond strength is a significant advantage of using Tyzor® catalysts in inks. This is critical in multilayer packaging structures, where delamination can compromise shelf life, product integrity, and regulatory compliance. By incorporating low levels (typically 1–4% by weight) of titanate catalysts, converters, and ink manufacturers can increase the durability of the bond without significantly altering other properties of the ink.
