Description and applications
TCA-IAM is an acetylacetone-free titanium chelate (butyl titanium phosphate). The
Phosphate ligand confers increased stability to the titanate compared with the titanium
Alkoxides. It is used as a printing ink additive to improve adhesion, heat
Stability and other resistance properties.
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
There is many references in the literature citing the use of TCA-IAM Originally conceived to provide amino thermoset reactivity, applications have expanded to include: Dispersion aid and physical property enhancer for use on the hardener side of nitrogen based epoxy curatives; Catalyst for phenolic resin manufacture; Urethane catalyst twenty-two times faster than DBTDL in 2-component urethanes; TiO2/Zn Molybdate/silicone-alkyd marine deck coatings; Increased tensile and flexibility of CaCO3 filled flexible PVC; Chemical reactivity for property enhancement of halogenated polymers; Adhesion promoter for epoxy, acrylic and urethane coatings to metals and polymers; Increased properties of Kevlar (aramid) reinforced, amide and anhydride cured epoxies; Increased conductivity of metal powder filled polymers, etc.
