NPB Solvent Hazard Information

  n-Propyl Bromide (nPB) also known as 1-Bromopropane or (1-BP), CAS # 106-94-5 is a brominated hydrocarbon solvent used in a variety of industrial applications, e.g. hand wipe, vapor degreasing, Ultrasonic cleaning, non-destructive inspection and aerosol dispensers commonly consumed for cleaning and degreasing among Aerospace, Electronics, Metal Working, Precision Optics, Asphalt Extraction (Bituminous Asphalt) and […]

n Propyl Bromide Solvent Information

How to Reduce Exposure to CAS 106-94-5 n-PB, 1-Bromopropane Solvent Substitution – Using Safer Alternatives The best way to reduce exposure is to switch to products that do not contain n-Propyl Bromide, nPB. There are lots of nonflammable solvents with high Kb values that do not require stabilizers, alkalinity testing and frequent, expensive disposal costs. […]

AK 225 Ban

HCFC 225 BAN 12-31-14 (CAS # 422-56-0 AND 507-55-1) Beginning January 1, 2015, HCFC-225 (also called “AK225”), a common precision solvent for high-end cleaning, will be banned for usage, per the Clean Air Act under the Montreal Protocol. HCFC-225 is a mixture of two isomers, HCFC-225ca and HCFC-225cb. A common source of HCFC-225 is from […]

AK-225 Replacement Options

Still using AK-225 (HCFC-225ca/cb)? Not for much longer. Depending on who you ask in the industry and US government regulatory agencies the official mandated phase-out date is December 31, 2014 for HCFC-225 commonly known as Asahiklin AK-225 for precision cleaning, 225AES, 225T and 225ATE for defluxing, drying where alcohol azeotropes are used, 225DH for displacement […]

AK-225 Replacement Options

So how much SHOULD you pay to replace AK-225? That depends on several factors such as Nonflammable? Solvency (Kb value)?  Need for azeotropes? Tolerance of chlorinated solvents? Toxicity exposure limits (PPM)? VOC content? In order to continue to operate with nonflammable solvents for your degreasing applications you have limited choices. Methylene Chloride, TCE and PERC […]
