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.
