Description

Tetraoctadecyl Orthotitanate is a high-purity organotitanium compound, also known as titanium(IV) stearate. This chemical serves as a highly effective catalyst and cross-linking agent, valued for its ability to modify surface properties and enhance material performance. It is primarily utilized in the polymer, coatings, and specialty chemical industries to improve adhesion, thermal stability, and hydrophobicity in final products.

Application

• Polymer Catalyst & Cross-Linker: Used as a catalyst in polycondensation reactions (e.g., for polyesters) and as a cross-linking agent for silicone resins and other polymers to enhance thermal and mechanical properties.
• Surface Modification Agent: Imparts hydrophobic and oleophobic characteristics to inorganic materials like glass, ceramics, and metals, improving water repellency and corrosion resistance.
• Adhesion Promoter: Functions as a coupling agent in coatings, inks, and composite materials to improve bonding between organic polymers and inorganic substrates.
• Lubricant & Grease Additive: Acts as a component in high-temperature lubricants and greases, contributing to stability and performance under extreme conditions.
• Specialty Coatings: Employed in the formulation of heat-resistant, anti-corrosive, and protective coatings for industrial and automotive applications.
• Pigment & Filler Treatment: Used to treat pigments and fillers (e.g., titanium dioxide, calcium carbonate) to improve their dispersion and compatibility in plastic and paint matrices.
