Excerpted from 10/25/12 white paper "Updated Facts On 2015 HCFC-225 Usage Ban" by Lindsey Shehan, Techspray Chemist.
 
About the HCFC-225 Phase-Out
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 Asahi Glass Company as Asahiklin AK-225, a precision cleaning solvent. AK-225 has many unique properties, including its ability to form azeotropes (mixtures that act as one chemical, with unique and constant physical characteristics), good solvency, and thermal stability (which makes it good for use in vapor degreasing).
 
AK-225 is nonflammable. AK-225 is VOC exempt, per the EPA. VOCs are smog producing compounds that are highly regulated. AK-225 also has a low acute toxicity (the exposure level of AK-225 is 100 ppm 8h TWA compared to 200 ppm for Trans), low viscosity (meaning that it flows well), high density (it’s heavier than water, it will displace water), and low surface tension (meaning that it will flow well under low stand offs). Unfortunately, due to the ozone depleting potentials of HCFC-225ca and HCFC-225cb, 0.02 and 0.03, respectively, it is now being phased out.
 
The table below summarizes the HCFC-225 phase-out:


What Are The Replacements for HCFC-225?
To date, the EPA has approved more than 300 substitutes for over 60 different uses. Potential substitutes for HCFC-225 include DuPont Vertrel Solvents, Techspray’s Precision-V Solvents, n-Propyl Bromide, Trichloroethylene, 3M HFEs, and Honeywell’s Solstice Performance Fluid.

PRECISION-V Replaces HCFC-225 with Performance & Safety Advantages



Techspray has engineered solvent cleaners that offer exciting new options for precision cleaning. Precision-V cleaners are powerful, leave no residue, evaporate extremely fast, and are non-flammable with no flash-point. Electronics, optics, and metal parts are quickly and thoroughly cleaned, eliminating the need for further rinsing. Precision-V is non-ozone depleting, so ideal replacements for cleaners containing Freon, HFC-141b and HCFC-225.
 
Precision-V Vapor-Degreaser solvents have azeotropic properties that allow it to maintain stable properties as it is cycled in a vapor-degreaser. It is not reactive or corrosive to metals commonly found in the construction of vapor-degreasers.
Exposure to Precision-V solvents is less hazardous than many other solvents commonly used in vapor-degreasers: e.g. TCE (Trichloroethylene, CAS #79-01-6), nPB (n-Propyl Bromide, CAS #106-94-5), and Perc (Perchloroethylene. CAS #000127-18-4).
 
Precision-V solvents have a lower boiling point than most other vapor-degreaser solvents. This reduces heat-stress on components being cleaned and reduces energy consumption from the boil sump and chiller coils.

Techspray Introduces ForeverSolv Solvent Reclaim Program



Techspray’s new ForeverSolv solvent reclaim program makes it possible to recycle and reuse cleaning solvents, eliminating the need for expensive waste disposal. Protect the environment while saving money!

Only Techspray offers this innovative program for our popular Precision-V and AK-225 vapor-degreasing solvents! With EPA exemptions in place, reclaimed AK-225 can continue to be used even after the 2015 phase-out date (see details above).

The ForeverSolv program is designed to be a no-hassle process. Techspray picks up the dirty solvent and drops o­ff cleaned solvent a month later. We do all the work, while you reduce your solvent usage and disposal costs. Since Techspray is handling the process, you can be assured the tightest tolerances are maintained. We certify every drum provided back to you, and include a certificate of analysis (COA).
