Applications and Performance
HW***1, 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
1. Catalyst:
As a catalyst HW***1 titanium acetylacetonate is used in an amount
of ca 0.***1 %. HW***1 titanium acetylacetonate is often added as
the last ingredient of the reaction components to prevent undesired
pre-reactions. Transesterifications run at low temperatures <
**0 C. Esterifications (e. G. Polyester preparation) need
temperatures of > **0 C.
2. Crosslinking:
For cross-linking reactions HW***1 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 > **0~**0
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 HW***1 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 *0~**0 C for a short
time might be of advantage.
5. Sol-Gel:
Total or partial hydrolysis of HW***1 titanium acetylacetonate
possibly in combination with other metal alkoxides affords metal
oxides for use as binder or coating.
