Tyzor 217 - Description
Tyzor 217 is a water-based zirconium chelate that is stable in water near neutral pH, making it an excellent choice for use in aqueous systems.
More information about Tyzor 217
Tyzor 217 can react with a variety of nucleophilic species such as -OH and -COOH groups. It is an effective crosslinking agent for carbohydrates (e.g., cellulose, starch and guar) and other functionalized polymers (e.g., polyvinyl alcohol). It is also effective as a surface modifier and adhesion promoter, enhancing paper, glass, metal, pigments and other materials having oxidized surfaces.
Tyzor 217 is usually formulated with other ingredients in cross-linking, paint and some coating applications. The zirconate is usually added as the last ingredient to prevent undesired pre-reactions. The time for gel formation depends on several factors, including: the formulation ingredients; type of polymer; temperature; pH; brine strength; and zirconate concentration.
For adhesion promotion or surface modification applications, Tyzor 217 can be applied as a primer from dilute solution.
