What problems do manufacturers face when it
comes to vapor degreasing?
The biggest challenge facing manufacturers who utilize
vapor degreasing is the need for a safe and sustainable
solvent. The most commonly used solvent, n-Propyl
Bromide (nPB), poses a safety risk to workers upon
exposure, and regulations have banned the use of HCFCs
like AK-225. Many manufacturers are now looking forsolutions that are safe for their employees and theenvironment, without sacrificing performance.
