Triisobutyl phosphate

Triisobutyl phosphate (CAS 126-71-6 ), also known as TIBP, is an organophosphate ester used across industrial and specialty chemical applications as a solvent, plasticizer, and defoamer.

Its controlled surface activity makes it effective at suppressing foam in process systems, while its solvency profile supports formulation work in coatings and polymer systems.

In coatings and adhesives, TIBP functions as a coalescing solvent and plasticizer, improving film formation and flexibility in finished products for various industrial applications.

Textile and paper processing operations use it as a defoaming agent in aqueous systems where foam buildup disrupts throughput and product quality during the manufacturing cycle.

Printing ink formulators incorporate TIBP as a solvent carrier to control viscosity and pigment dispersion, ensuring consistent application and color quality in high-speed printing.

In polymer and elastomer compounding, it acts as a secondary plasticizer and flame-retardant additive, contributing to both processability and compliance with fire performance requirements.

Triisobutyl phosphate is supplied as a clear liquid in standard drum and IBC packaging. Technical grade is the primary commercial form, meeting purity specifications for industrial use.

Specialty grades aligned to coatings or polymer end-use requirements may be available depending on supplier qualification standards and specific customer technical needs.
