Solubility: Soluble in isopropyl alcohol, xylene and toluene. Reacts with DOP and H2O.

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.

Application and performance
TCA-L*2 can be used in composite materials to improve thermal stability, surface smoothness and loading level of fillers to reduce the dosage of resin and reduce the cost.
It can be applied to polymers including PP, PE and rubber. TCA-L*2 is a surface treatment agent for inorganic fillers such as calcium carbonate, kaoline, talcum etc, to improve hydrophobic property and dispersion of the filler. As a result, the products treated by this product will obtain improved mechanical strength, reduced moisture absorption.
When rubber is filled by the filler of kaolin treated by TCA-L*2, the rubber can obtain improved tearing strength and tensile strength. So silica can be partly replaced.
