Tyzor® TEAZ by Dorf Ketal is an adhesion promoter. It possesses crosslinking properties. It offers benefits such as enhanced curing, improved chemical, solvent and water resistance and enhanced heat resistance. Tyzor® TEAZ provides improved crack resistance, enhanced stability and compatibility of pigment dispersions and colorants and improved gloss.
Tyzor® 217 by Dorf Ketal is an aqueous solution of zirconium lactate, and sodium salt. It acts as an adhesion promoter, as cure catalysts, and an effective crosslinking agent. It is a water-based zirconium chelate that is stable in the water near neutral pH. It can react with a variety of nucleophilic species such as -OH and -COOH groups. It helps in crosslinking carbohydrates (e.g., cellulose, starch, and guar) and other functionalized polymers (e.g., polyvinyl alcohol). Tyzor® 217 is used in water-based adhesives such as epoxy, polyurethane, and polyvinyl acetate.
Triethanolamine titanium complex. It has 80% active ingredient in alcohol solvent. Acts as a catalyst and as an adhesion promoter. It is stable to moisture. It has moderate to fast reaction rate, low toxicity, provides high yield, easy work-up at low catalyst concentration. Used in esterification, transesterification, condensation and addition reactions. It is especially well suited to direct esterification processes due to its excellent compatibility with the water byproduct. It can be used in polysulfide and acrylic (water-based).
