Abstract： 

TCA-K12 (TCA-102) is a liquid monoalkoxy fatty acid titanate that is compatible to semi-polar and nonpolar material.

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.

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.

Suggested Functions- Coupling agent, adhesion promoter, catalyst, repolymerization catalyst, copolymerization catalyst, regrind regenerator, polymer strain and mechanical property improver, dispersion aid, deagglomerator, wetting agent, surfactant, grinding aid, plasticizer or solvent reducer, superplasticizer, low temperature flexibilizer, process aid, peptizer, flow control agent, lubricant, viscosity depressant, thixotrope, suspension aid, impact modifier, comonomer, Lewis Acid reducing agent, hydrophobic agent, cure rate modifier, blowing agent activator, intumescent activator, flame retardant, conductivity enhancer, corrosion inhibitor, anti-aging inhibitor, etc. Function depends on dosage, solubility parameters, dilution, sequencing, process conditions, substrate, polymer, other ingredients, curatives, etc. and their interaction with the neoalkoxy, octyl, phosphato and titanium functionalities of TCA-K12 (TCA-102).

Some Commercial Applications- This product 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. It 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 it, the rubber can obtain improved tearing strength and tensile strength. So silica can be partly replaced.

There are numerous references in the literature citing the use of it. It may be used in high temperature processing thermoplastics when applied as a masterbatch pellet. Applications include: faster cycles @ lower temperatures for thermoplastic and elastomer polymer processing; copolymerization of dissimilar polymers in the melt; regeneration of regrind; improved mechanical properties of CaCO3, mineral and metal oxide filled polymers; control of burn rate and burn rate exponent in energetics and FR compositions; viscosity reduction; adhesion promotion; catalyst; dispersant, etc.
