Propylene Glycol Butyl Ether (PNB), CAS 5131-66-8, also known as propylene glycol monobutyl ether or 1-butoxy-2-propanol, is a glycol ether with dual hydrophilic and lipophilic characteristics. It appears as a colorless transparent liquid with a mild characteristic odor. PNB is partially soluble in water and miscible with most organic solvents, a property profile that supports its function as both a coupling agent and a solvent across multiple industrial formulations.
PNB is used in commercial procurement for its ability to solvate and couple hydrophobic greases and oils in aqueous systems, as well as its capacity to lower surface tension and support film formation in coating applications. Its evaporation rate sits between fast-evaporating and slow-evaporating glycol ethers, making it suitable for systems requiring balanced drying performance.
TICHEM supplies industrial grade PNB to business buyers in the coatings, cleaning products, printing inks, and agricultural chemical sectors. Backed by 13 years of functional solvent supply chain experience and parent company Titan Technology (STAR Market listed, stock code 688133), TICHEM provides supply consistency and technical support for industrial operations.

The specifications above represent typical physical properties of industrial grade PNB. With a flash point of 63°C (Setaflash Closed Cup method), PNB is classified as a flammable liquid Category 4 and requires appropriate storage and handling measures. Its boiling point of 171°C and evaporation rate of 0.093 position it as a mid-range evaporating solvent suitable for formulations requiring controlled drying.
PNB functions as a coalescent in water-borne latex coatings, lowering the minimum film formation temperature (MFFT) and promoting uniform film formation during the drying process. In architectural and industrial water-based coatings, it contributes to film integrity and appearance characteristics. For formulators targeting fast-evaporation coating systems, PNB offers coalescing performance with balanced evaporation speed.
PNB serves as a coupling agent and solvent in industrial cleaning formulations, including heavy-duty cleaners, grease and paint removers, metal cleaners, and hard surface cleaners. Its ability to couple hydrophobic oils and greases into aqueous systems supports the development of water-based cleaning products for commercial and industrial maintenance operations.
In printing ink formulations, PNB acts as an active solvent for solvent-based systems and as a coupling agent for water-reducible ink systems. Its solvency properties and surface tension characteristics contribute to ink flow, leveling, and substrate wetting performance.
PNB functions as a coupling agent in water-based agricultural chemical formulations, supporting the stabilization of active ingredients and adjuvants in aqueous systems. This application serves the agricultural chemical manufacturing sector.
PNB serves as a chemical intermediate in the production of epoxides, acid ester derivatives, solvents, and plasticizers. Its hydroxyl and ether functional groups provide reactive sites for further chemical synthesis.
