What is Triisobutyl phosphate?
Triisobutyl phosphate (CAS 126-71-6), also known as TIBP, is an organophosphate ester used as a solvent, plasticizer, and defoamer.
Where is Triisobutyl phosphate used?
- Coatings and adhesives: coalescing solvent and plasticizer for film formation and flexibility
- Textile and paper processing: defoaming agent in aqueous systems
- Printing inks: solvent carrier controlling viscosity and pigment dispersion
- Polymer and elastomer compounding: secondary plasticizer and flame-retardant additive
- It suppresses foam in process systems through controlled surface activity.
Commercial specifications
- Standard drum and IBC packaging
- Technical grade meets purity specifications for industrial use
- Specialty grades for coatings or polymer end-use may be available depending on supplier qualification standards
