Details

FD-TnPT can be used directly or indirectly as
a catalyst or catalyst additive, as a coating primer or
added to a formulation as a adhesion promoter and as
the base material in the formation of sol-gel systems
or nanoparticle systems or products. Some typical
applications for FD-TnPT are:
Catalyst:
As esterification catalyst FD-TnPT is used in
an amount of ca 0.01-1 %. The titanate is often added
as the last ingredient of the reaction components to
prevent undesired pre-reactions. Transesterifications
run at low temperatures < 100 degree. Esterifications
(e.g. plasticizer preparation) need temperatures of >
180 degree. For Ziegler-Natta catalysis FD-TnPT
is mainly used in combination with Al compounds.
Crosslinking:
For cross-linking reactions FD-TnPT is added
to the polymer / binder in concentrations of ca. 0.5 -
5 %. The reactivity of FD-TnPT is very high;
depending on the polymer sometimes other less
reactive FD-TnPT products have to be used.
Coating:
Titanium dioxide layers can be prepared by thermal
or hydrolytic degradation of FD-TnPT.
Thermal decomposition occurs at > 350 - 600 degree.
FD-TnPT is preferably applied by vapor
deposition in a stream of a dry gas or by spraying
forming on a hot substrate a thin layer of titanium
dioxide. By spraying, dipping or brushing of the
substrate from solutions and subsequent hydrolysis
by moisture also TiO2 layers are formed.
Primer:
As primer FD-TnPT is applied normally in
very low concentrations of ca. 0.1-5 % in an organic
solvent. Heating after appliance to ca. 80-100 degree for
a short time might be of advantage.
Gel:
Total or partial hydrolysis of FD-TnPT
preferably in the presence of chelating agents or in
combination with other metal alkoxides affords via a
sol-gel step metal oxides for use as binder or coating.
