Corrosion Protection

Catalysts for Corrosion Protection

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.

Tyzor® additives also enable formulators to lower the cure temperature and reduce the dry film thickness of coatings, both of which are essential for energy-efficient and cost-effective manufacturing processes. This is particularly relevant for coil coatings and pre-painted metals, where oven throughput and uniformity are key operational concerns. Their compatibility with solvent-based and water-based systems also allows for flexibility in formulation, enabling compliance with regulatory restrictions on VOCs and hazardous air pollutants. 

Moreover, in applications such as wire enamels and electrical insulation coatings, Tyzor® catalysts provide faster curing and enhanced thermal stability. These benefits improve productivity and longer service life in high-voltage electrical components, meeting critical performance standards such as those established by NEMA. 

Dorf Ketal continues to address evolving industry needs by developing low-VOC titanates and zirconates that offer superior performance in next-generation coatings. As demand increases for environmentally compliant, high-performance metal coatings, Tyzor® catalysts provide a proven, scalable solution.
