• Non-toxic

Dorf Ketal Tyzor® organic titanates and zirconates are adhesion promoters and cross-linkers that are essential additives for flexographic and gravure printing inks.

The unique properties of the Tyzor® products enhance the performance of printing inks in a variety of applications. One specific application is flexible packaging.

Flexible packaging has become an important component of product marketing. Packaging materials usually include a non-absorbing foil based on polyolefin (polyethylene, polypropylene, or co-extruded polypropylene), polyester, polyamide, cellophane, polyvinyl chloride, metallized plastic, or aluminum. Important product information is printed on these foils to motivate consumers to purchase the products, provide details, and for decorative purposes.

Typical print platforms for flexible packaging are flexography and rotogravure processes that require specialized inks. The type of ink most often used contains nitrocellulose (NC) as the primary binder.

Benefits

For flexo and gravure package printing, Tyzor® titanates and zirconates help improve the final product properties. This is achieved by increasing the cross-linking which provides the following benefits:

1. Improved adhesion of the ink to the substrate
2. Enhanced curing
