Abstract

Titanate Coupling Agent FD**8 (CAS No. **********8) is a neoalkoxy titanate coupling
agent, it has a better thermostability compared to traditional monoalkoxy
titanates. Its function is similar to Ken-React LICA *8 from Kenrich
Petrochemicals, Inc.

Applications and Performance
Coupling Agents are molecular bridges at the interface between two substrates,
usually but not limited to an inorganic filler/fiber and an organic polymer
matrix. Titanium-derived coupling agents react with free protons at the
inorganic interface resulting in the formation of organic-titanium
monomolecular layers on the inorganic surface. Additionally, the coupling agent
may have up to Six Functions in the matrix-which include polymer catalysis and
other heteroatom effects-independent of inorganic content.

Typically, titanate-treated inorganics are hydrophobic, organophilic, and
organofunctional. Fillers may be pretreated or treated in situ absent water of
condensation and drying techniques as needed with silanes. When used in
polymers, titanates can increase adhesion; Improve impact strength and
mechanical properties; Reduce embrittlement; Allow higher filler loadings;
Optimize particulate dispersion; Increase flow of filled and unfilled polymers
at lower process temperatures; Prevent phase separation; And may have other
effects.

Reactive Substrates

Proton reactivity allows coupling to almost all inorganic and organic substrates such
as CaCO3, carbonates, carbon black, graphite, minerals, nano-particulates,
silicas, silicates, metals, metal oxides, peroxides, hydrates, acetates,
borates, sulfates, nitrates, nitramines, aramid, organic pigments, cellulosics,
sulfur, azodicarbonamide, polymers, etc.
 

Some Commercial Applications

Ttreat inorganic fillers such as calcium carbonate, barium sulfate, etc, so
that improved processing rheological property, higher loading of fillers,
improved mechanical performance can be obtained.

Improve dispersion, hiding power and coloring power for pigments, to improve
anticorrosion, water resistance, flame retardance.

In high loading of aluminum hydroxide filled fiber glass reinforced polyester,
not only preventing fillers precipitating in the liquid resin, but also
improving flame retardance. Rubber products can be improved in tensile
strength, tearing strength, elongation at break and aging resistance.

Used as coupling agent not only for inorganic fillers with resins, but also for
non-polar materials with polar materials.
