Description

Isopropyl Tri(Dioctylpyrophosphate) Titanate is a specialized organotitanate coupling agent, widely recognized by its CAS number 67691-13-8. This compound is engineered to significantly enhance the compatibility and adhesion between inorganic fillers and organic polymer matrices. It is an essential additive for manufacturers seeking to improve the mechanical properties, dispersion, and processing of composite materials. Key industries that rely on this advanced coupling agent include plastics, coatings, adhesives, and advanced rubber compounding.

Application

• As a coupling agent to improve the bonding between mineral fillers (e.g., calcium carbonate, talc, silica) and polymer resins like polyolefins, PVC, and engineering plastics.
• To enhance dispersion and reduce viscosity in filled polymer systems, leading to improved processability and surface finish in masterbatches and compounds.
• In coating formulations to increase adhesion to metallic and inorganic substrates, improving corrosion resistance and durability.
• For the surface treatment of pigments and nanomaterials to prevent agglomeration and ensure uniform distribution within the matrix.
• In adhesive and sealant systems to boost water resistance and overall bond strength, especially in challenging environments.
• As a key component in the production of high-performance, filled elastomers for the automotive and industrial sectors.
