Arcosolv PNB Propylene Glycol Normal Butyl Ether 5131-66-8 Lyondell North America South and Central America Western Europe Central and Eastern Europe Middle East and Central Asia Asia / Pacific Film forming /coalescing agents Solvent >> Glycols & glycol ether >> Propylene Glycol Acrylic/Acrylate Resins Vinyl Coatings >> Solventborne INKS ARCOSOLV PNB - (Mono) Propylene Glycol Normal Butyl Ether - is a colorless combustible liquid with an ether-like odor. It has low water solubility and good coupling and demonstrates good solvency for coating resins. The properties of PNB support its use in agricultural, coating, cleaning, ink, textile and adhesive products. It is a good substitute for ethylene glycol ethers including EB. Coatings: ARCOSOLV PNB can be used as a coalescent with various resins including Acrylics, Styrene-Acrylics, and Polyvinylacetates. It has superior film forming characteristics. Cleaners: ARCOSOLV PNB has a moderate odor, good coupling ability, and good surface tension lowering in water-based cleaners. It is compatible with a wide range of cleaning components. ARCOSOLV PNB is also partially water soluble and the water solubility can be increased by adding low molecular weight alcohols or other propylene glycol ethers. Other Applications: The properties listed in the previous section also support the use of ARCOSOLV PNB in agriculture, cosmetics, electronics, ink, textile and adhesive products. Specific end uses may require approval by appropriate regulatory agencies Propylene Glycol Normal Butyl Ether. Used in coating and ink. Offers low water solubility. Provides good coupling and solvency.
