TCA-K38S Isopropyl Tri(Dioctylpyrophosphate) Titanate (CAS No. 67691-13-8) CAS NO.67691-13-8

isopropyl tri(dioctylpyrophosphate) titanate (cas no. 67691-13-8), titanate coupling agent tca-k38s, is a liquid monoalkoxy pyrophosphate titanate which is compatible to polar material like pvc, pa, etc.

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.

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 (see “suggested functions”).

titanate tca-k38s provide: a method for filler/pigment coupling (or bonding) at temperatures above 100℃ in the thermoplastic melt phase via a proposed proton coordination mechanism, absent the need of water condensing mechanisms as with silanes, to a wide variety of substrates heretofore considered non-reactive with silanes; and for in-situ metallocene-like repolymerization catalysis of the filled or unfilled polymer during the compounding, extrusion and blow or injection molding plastication phase resulting in significantly faster production cycles at lower temperatures of thermoplastic parts having better finish and equal or better mechanical properties.
