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.

Paints and coatings serve a dual purpose in industrial and commercial applications: protecting substrates from environmental degradation and enhancing visual and functional properties such as color, gloss, corrosion resistance, and chemical durability. Dorf Ketal’s Tyzor® catalysts provide a powerful set of tools for formulators seeking to improve the performance of waterborne, solvent-based, and 100% solids coating systems.
Tyzor® organotitanates, and organozirconates are highly effective as crosslinking agents, adhesion promoters, and reactive modifiers. They function by interacting with functional groups in the binder resins—such as hydroxyl, carboxyl, or amine groups—in systems based on polyurethane, epoxy, or acrylic chemistries. This leads to denser, more chemically resistant polymer networks with superior film integrity.
In solvent-based coatings, Tyzor® catalysts enhance curing, reduce dry times, and increase compatibility with inorganic pigments and fillers. This results in improved rheology, better pigment dispersion, and enhanced mechanical properties such as scratch resistance and hardness. These benefits are particularly valuable in protective coatings for metal substrates, including machinery, automotive components, and industrial equipment.

Metal coatings serve as critical protection and performance layers in industries ranging from automotive and aerospace to construction and electronics. Dorf Ketal’s Tyzor® catalysts play a vital role in enhancing the performance of these coatings by acting as both adhesion promoters and functional catalysts. These titanate and zirconate compounds are particularly effective in corrosion-resistant primers, coil coatings, and conductive layers, where metal-to-coating interface durability is essential.
One of the most important roles of Tyzor® catalysts in metal coatings is enhancing corrosion resistance. By introducing organotitanate molecules into primer formulations—especially those containing sacrificial metals like zinc—Tyzor® compounds contribute to forming a tightly bonded, chemically resistant layer that prevents oxidation and surface degradation. This is particularly valuable in thin-film coatings where traditional pigment volume concentration is insufficient to ensure long-term protection.
The unique chemistry of Tyzor® compounds allows them to act as adhesion promoters and inorganic network formers. When applied to metal substrates, especially those exposed to harsh environmental conditions (e.g., automotive fasteners, clamps, and chassis components), titanates can form a reactive TiO₂ layer that chemically binds to the metal surface. This layer serves as a foundation for subsequent coating layers, improves mechanical adhesion, and prevents delamination under thermal and mechanical stress.

Polyethylene Terephthalate (PET) is one of the world’s most widely produced thermoplastic polyesters, used in applications ranging from beverage bottles and food containers to textile fibers and engineering resins. In the production of PET, the choice of catalyst plays a critical role in determining the efficiency of the polymerization process and the final product’s physical and mechanical properties.
Dorf Ketal‘s ACtivate™ and Tyzor® titanate catalysts offer significant advantages over traditional metal-based catalysts such as antimony trioxide or manganese acetate. These organotitanium compounds act as highly effective esterification and polycondensation catalysts, enabling manufacturers to achieve high molecular weight PET with lower color formation, faster reaction rates, and improved downstream processability.
In the melt phase of PET production, ACtivate™ and Tyzor® catalysts promote the transesterification of dimethyl terephthalate (DMT) or the direct esterification of terephthalic acid (PTA) with ethylene glycol (EG). This reaction forms oligomers that are subsequently polycondensed into high-molecular-weight PET. The use of ACtivate™ and Tyzor® catalysts enables efficient conversion with reduced side reactions, such as olefin formation, which can lead to color bodies or undesirable byproducts.

Tyzor® organic titanates and zirconates are highly effective Lewis acid catalysts for esterification and transesterification reactions. Developed and optimized over five decades, these catalysts are widely used in producing acrylate esters, plasticizers (e.g., phthalates), and polyester resins such as PET and PBT.
In transesterification, Tyzor® alkoxide-based catalysts—such as Tyzor® TPT, TPT-20B, and TnBT—are noted for their high reactivity and fast conversion rates under anhydrous conditions. These catalysts promote the efficient exchange of ester groups between molecules with minimal byproduct formation. As long as water is excluded, the reaction proceeds cleanly, making these catalysts ideal for producing high-purity esters in continuous or batch processing.
Tyzor® catalysts differ in their moisture sensitivity. Lower molecular weight alkoxides are highly reactive but must be carefully handled in moisture-free environments. For systems where some exposure to water is unavoidable, higher molecular weight alkoxides such as Tyzor® TOT and stable chelates like Tyzor® TE provide enhanced hydrolytic stability. These grades may require slightly higher temperatures and reaction times but are compatible with a broader range of process conditions and raw materials.

Glass is used in a broad array of structural, decorative, and high-tech applications. Its properties can be significantly enhanced by surface treatments designed to modify adhesion, optical behavior, resistance, and functionality. Tyzor® organic titanates and zirconates, developed by by Dorf Ketal, offer a high-performance solution for the surface treatment of glass. These compounds function as adhesion promoters, surface modifiers, and functional catalysts, improving durability and performance.
Tyzor® compounds apply to many forms of glass, including:
As adhesion promoters, Tyzor® materials improve bonding between glass substrates and coatings or polymer matrices. They can be applied as primers in pre-treatment steps or added directly to coating formulations. The result is a substantial enhancement in resistance to water, chemicals, and mechanical abrasion.
