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.
