Description

Tetraisopropyl Di(Dioctylphosphate) Titanate is a specialized organotitanium coupling agent and adhesion promoter. This compound is valued for its ability to significantly improve the compatibility and bonding between inorganic fillers and organic polymer matrices. It is primarily needed by manufacturers in the plastics, coatings, and composite materials industries seeking to enhance product performance, durability, and processing characteristics.

Application

• As a coupling agent in filled polyolefin (PP, PE) and engineering plastic composites to improve mechanical properties and dispersion.
• As an adhesion promoter in paints, coatings, and inks to enhance bonding to metallic and mineral substrates.
• To improve the wetting and dispersion of pigments and fillers (e.g., calcium carbonate, talc, silica) in polymer systems.
• In the formulation of sealants and adhesives to increase bond strength and moisture resistance.
• For surface treatment of glass fibers and minerals to improve resin compatibility in fiber-reinforced plastics (FRP).
• As a crosslinking agent or catalyst in specific silicone and polymer synthesis reactions.
