Formulators benefit from the ability of Tyzor® products to fine-tune open time and green strength. Open time refers to the period available for repositioning or adjustment after application, while green strength defines the bond's holding capability before full cure. Adjusting the catalyst loading—typically in the range of 0.5–5% by weight—allows for precise control over these parameters, ensuring optimized processability and throughput. 

The Unilink® catalyst series complements Tyzor® in polyurethane-based adhesives, where curing kinetics and hardness development must be finely controlled. Unilink® 2200 and 2500 catalysts offer delayed reactivity, ideal for two-component adhesive systems requiring long pot life and high final performance. They also contribute to consistent curing under variable ambient conditions, especially in field-applied adhesives or construction sealants. 

Environmentally, both catalyst platforms support the industry's move toward low-VOC, heavy metal-free formulations. They effectively replace organotin and mercury compounds, enabling compliance with REACH, RoHS, and global sustainability standards without sacrificing technical performance. 

In demanding industrial bonding applications—where strength, speed, and reliability are essential—Dorf Ketal's Tyzor® and Unilink® catalysts provide the performance edge needed to meet modern challenges. Whether you are developing adhesives for automotive assembly, structural laminates, or high-end consumer goods, these catalysts deliver superior control, durability, and sustainability.
