Applications and Performance
TiLink TCA-AA105, titanium acetylacetonate, can be used in a variety of applications that involve its reactive properties. It is mainly used as an adhesion promoter in flexographic and gravure printing inks. It offers benefits such as ehanced curing, improved chemical, solvent and water resistance and enhanced heat resistance. Provides improved crack resistance, enhanced stability and compatibility of pigment dispersions and colorants and improved gloss. The items below describe a few of the more salient features
1. Catalyst:
As a catalyst TiLink TCA-AA105 titanium acetylacetonate is used in an amount of ca 0.01-1 %. TiLink TCA-AA105 titanium acetylacetonate is often added as the last ingredient of the reaction components to prevent undesired pre-reactions. Transesterifications run at low temperatures < 100 C. Esterifications (e. G. Polyester preparation) need temperatures of > 180 C.
2. Crosslinking:
For cross-linking reactions TiLink TCA-AA105 titanium acetylacetonate is added to the polymer / binder in concentrations of ca. 0.5~5 %.
3. Coating:
Titanium dioxide layers can be prepared by using thermal or hydrolytic processes. Thermal decomposition occurs at > 350~600 C. By spraying, dipping or brushing of the substrate from solutions and subsequent hydrolysis by moisture also TiO2 layers are formed.
4. Primer:
As primer TiLink TCA-AA105 titanium acetylacetonate is applied normally in very low concentrations of ca. 0.1~5 % in an organic solvent such as isopropanol. Heating after application to 80~100 C for a short time might be of advantage.
5. Sol-Gel:
Total or partial hydrolysis of TiLink TCA-AA105 titanium acetylacetonate possibly in combination with other metal alkoxides affords metal oxides for use as binder or coating.
Packing
25 liters plastic pail and 200 liters steel drum.
