TiLink TCA-AA is titanium acetylacetonate bis(pentane-2,
4-dionato-O, O')bis(alkanolato)titanium, is a titanium chelates
with acetylacetone as chelating agent with CAS No. 17927-72-9. It
is the equivalent product to TyzAA from DuPont.
Chemical Name: Bis(acetylactonate) diisopropoxide titanium

TiLink TCA-AA, titanium acetylacetonate, can be used in a variety
of applications that involve its reactive properties. The items
below describe a few of the more salient features
As a catalyst TiLink TCA-AA titanium acetylacetonate is used in an
amount of ca 0.01-1 %. TiLink TCA-AA 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.
Fcross-linking reactions TiLink TCA-AA titanium acetylacetonate is
added to the polymer / binder in concentrations of ca. 0.5~5 %.
Titanium dioxide layers can be prepared by using thermal hydrolytic
processes. Thermal decomposition occurs at > 350~600 C. By
spraying, dipping brushing of the substrate from solutions
subsequent hydrolysis by moisture also TiO2 layers are formed.
As primer TiLink TCA-AA titanium acetylacetonate is applied
normally in very low concentrations of ca. 0.1~5 % in anganic
solvent such as isopropanol. Heating after application to 80~100 C
fa short time might be of advantage.
Total partial hydrolysis of TiLink TCA-AA titanium acetylacetonate
possibly in combination with other metal alkoxides affords metal
oxides fuse as binder coating.
