Tripropylene glycol n-butyl ether

Tripropylene glycol n-butyl ether (CAS 55934-93-5), also known as TPBGE, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and adhesive formulations. Its controlled evaporation rate supports film formation and flow in demanding industrial applications. In architectural and industrial coatings, TPBGE functions as a coalescing solvent and flow promoter.

This chemical improves film leveling and reduces surface defects in waterborne systems. Printing ink formulators use it to control viscosity and drying profiles in packaging inks, particularly where extended open time is required. Automotive refinish and underbody coating formulations incorporate it to enhance substrate wetting and adhesion. It also performs as a heavy-duty degreasing solvent in industrial cleaning compounds.

The solvent is highly effective for targeting metal surfaces and tooling equipment. Tripropylene glycol n-butyl ether is supplied as a clear liquid in standard packaging including drums and IBC totes. Bulk availability is maintained for high-volume industrial buyers. It is offered primarily in technical grade, suited for coatings, adhesive, and industrial cleaning applications.

Purity specifications typically align with solvent-grade requirements. Suppliers may offer material with documented physical and compositional certificates of analysis to ensure consistent performance.
