What is 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.
Where is Tripropylene glycol n-butyl ether used?
- Architectural and industrial coatings: coalescing solvent and flow promoter
- Waterborne systems: improves film leveling and reduces surface defects
- Packaging inks: controls viscosity and drying profiles where extended open time is required
- Automotive refinish and underbody coatings: enhances substrate wetting and adhesion
- Industrial cleaning compounds: heavy-duty degreasing solvent for metal surfaces and tooling equipment
- Adhesive formulations incorporate it as a solvent.
Commercial specifications
- Purity specifications typically align with solvent-grade requirements
- Suppliers may offer material with documented physical and compositional certificates of analysis
