Applications Performance
Coupling Agents are molecular bridges at the interface between two substrates, usually but not limited to an inorganic filler/fiber anganic polymer matrix. Titanium-derived coupling agents react with free protons at the inorganic interface resulting in the formation ofganic-titanium monomolecular layers on the inorganic surface. Additionally, the coupling agent may have up to Six Functions in the matrix-which include polymer catalysis other heteroatom effects-independent of inorganic content.
Typically, titanate-treated inorganics are hydrophobic,ganophilic,ganofunctional. Fillers may be pretreated treated in situ absent water of condensation drying techniques as needed with silanes. When used in polymers, titanates can increase adhesion; Improve impact strength mechanical properties; Reduce embrittlement; Allow higher filler loadings; Optimize particulate dispersion; Increase flow of filled unfilled polymers at lower process temperatures; Prevent phase separation; may have other effects.

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

Some Commercial Applications
There is many references in the literature citing the use of TCA-k44.iginally conceived to provide amino thermoset reactivity, applications have expanded to include: Dispersion aid physical property enhancer fuse on the hardener side of nitrogen based epoxy curatives; Catalyst fphenolic resin manufacture; Urethane catalyst twenty-two times faster than DBTDL in 2-component urethanes; TiO2/Zn Molybdate/silicone-alkyd marine deck coatings; Increased tensile flexibility of CaCO3 filled flexible PVC; Chemical reactivity fproperty enhancement of halogenated polymers; Adhesion promoter fepoxy, acrylic urethane coatings to metals polymers; Increased properties of Kevlar (aramid) reinforced, amide anhydride cured epoxies; Increased conductivity of metal powder filled polymers, etc.
