Glycol Ether PnB
Glycol Ether PnB (propylene glycol n-butyl ether) is a practical alternative to Glycol Ether EB and other degreasing solvents.
PnB is an outstanding solvent and coupling agent. It is in the P-series glycol ether family, which are significantly safer and less toxic than the E-series glycol ethers (derived from ethylene oxide) . The P series and in aprticular Glycol Ether PNB are generally considered to be more acceptable for the environment when used in cleaners. It has a favorable environmental profile because it is readily biodegradable and has low aquatic toxicity.
Favorable environmental characteristics include -
- More Rapid biodegradability: PnB breaks down more quickly in the environment. Aerobic biodegradation has been shown to be 60% to 90% complete within 28 days. In water, it can break down in a matter of days.
- Lower Toxicity in water - PnB has very low toxicity to aquatic organisms such as fish and invertebrates.
- Lower toxicity in air - PnB has a short atmospheric half-life, meaning it breaks down relatively quickly in the air.
Glycol Ether PnB works by lowering the surface tension of cleaning solutions to improve the wetting of the surface to be cleaned and to penetrate the layer of soil to be removed, so it works better and more efficiently. It also evaporates faster and has high solvency.
In coatings, it offers good coalescing ability in systems requiring fast evaporation. Overall PnB is an outstanding solvent and coupling agent because it combines the characteristics of alcohols and ethers.
Glycol Ether PnB is partly water soluble and miscible with most organic solvents. To increase solubility other glycol ethers or alcohols can be added.
Glycol Ether PnB offers great benefits for cleaning, degreasing, coatings, and many other formulations.
